One of lightweight series: carbon fiber wave of industrialization

2016-09-22

　The core idea:
1. The lightweight or breakthrough into manufacturing industry

When the industry's economic malaise falling demand, lightweight is expected to become the breach of the manufacturing industry development. In the new energy automotive industry, for example, in order to solve the problems of the new energy vehicle range is short, it is difficult to achieve greater breakthrough in energy efficiency in the short term under the reality, auto lightweight industry attention gradually.

The same orbit and aviation vehicle manufacturing, lightweight transformation also has played a pivotal role. Current lightweight mainly involves four materials: carbon fiber composite materials, aluminum alloy, magnesium alloy and high strength steel. The selection of these materials, often from the cost, and the connection of the metal, repair and recovery comprehensive considerations. Lightweight brings not only the innovation of materials, but also the industrial chain of reforming and the demand for manufacturing equipment activation.

2. Lead lightweight carbon fibre material wave

Carbon fiber material to denote made of carbon fiber and polymer resin composite carbon fiber composite materials. Due to the characteristics of high strength + low density, the application of carbon fiber composite material has been closely watched. Body/carbon fiber composite material fuselage sections for molding is an organic whole, so it saves a lot of fasteners, fittings, welding materials, such as the accessory structure weight, so the weight is not only the material itself, also get additional weight is reduced,

the future integration of carbon fiber composites forming technologies are expected to resume of vehicles, aircraft and other equipment to reduce the huge role. At present the development of carbon fiber industry mainly restricted to import high-end strand upstream and middle parts molding cost control as well as the release of the downstream demand.

3. The carbon fiber production process and related equipment and parts

Carbon fiber precursor production involves drawing, drawing, carbonization and graphitization, and other links, which the technical difficulties of carbide link and produce the highest added value. Carbon fiber related production equipment mainly from two aspects,

on the one hand, is the production of carbon fiber strand equipment, on the other hand is a carbon fiber strand compressed into composite materials as well as the final parts molding equipment. The rise of new energy vehicles industry is expected to drive the rapid release of carbon fiber downstream demand, and related equipment manufacturers in the whole industry chain will take the lead in industrialization of dividends.

4. The domestic carbon fiber production equipment listed company

Sea machinery: carbon fiber lightweight business research and development continue to push forward, new energy vehicles carbon fiber body parts production line automation design has been completed, the company is expected in March 2017 for installation debugging, trial production. At the same time the company has contact with many car companies to explore the application of carbon fiber lightweight components development work. Chu river: new materials,

A breakthrough, lightweight, or become a manufacturing development
1 lightweight help new energy vehicles to lengthen life

In the first half of the China association of automobile manufacturers, according to China's new energy vehicle production and sales of 177000 and 170000, respectively, year-on-year growth of 125% and 125% respectively. The new energy automotive industry under TuiPo of subsidies, such as negative influence twists and turns, the next few years is expected to remain strong. For the new energy car itself, hidden behind the battery motor electronic control system problem is the central issue of ascension life.

New energy vehicles in order to solve the problem of short range over the years, the battery world has introduced new technology, improve the battery materials, technology, process improvement. But after several material and technical route change, energy efficiency is more difficult to achieve greater breakthroughs in a short time, so the industry began to deflect, continuing research and development of new energy storage technology at the same time, begin to pay close attention to automotive lightweight technology, through the weight loss reduction interface to achieve energy efficiency, so as to further extend the new energy electric vehicle range.

Lightweight is closely connected with the new material, 4 big future lightweighting mainly involved in the field of industrial materials, carbon fiber composite materials, aluminum alloy, magnesium alloy and high strength steel. From the Angle of material strength and weight, on the basis of consumption of steel 400 kg. Need high strength steel is 320 kg, 240 kg of aluminum alloy, magnesium alloy 220 kg, 160 kg composite materials, thick calculate weight loss potential respectively: 10% to 20%, 40%, 50%, 60%.

Quantitative analysis on the economic benefits of passenger car weight loss: for ordinary passenger cars, a car for every 100 kg weight, fuel consumption is reduced an average of 0.5 L per hundred kilometers, there is less carbon dioxide emissions of 500 g. As you can see, the weight loss is of great significance to promote the efficiency of fuel.

Mentioned auto lightweight, people first think of its security problems, namely the body after lightweight material strength is not enough and the concerns of the problems such as low weight. Auto lightweight, actually is to assure the safety of the car's speed and performance under the premise of as much as possible to reduce curb weight of the vehicle. Weight loss after the car has many advantages, such as greener, more fuel-efficient, driving speed, and ability to respond to improve control performance. In addition to the auto lightweight, including rail delivery and industrial manufacturing sector are lightweight explored, some even walk in the forefront of the automotive industry.

2 lightweight power rail transit authors efficiency

Railway freight cars
On-orbit to pay the freight vehicles, lightweight transformation also has played a pivotal role. Tram statistics, according to the manufacture of aluminum alloy under the condition of equal strength, aluminum alloy car is about 20% less than steel car weight. Is of type C80 aluminum alloy coal gondola car for daqin railway in our country to improve the transport capacity, achieve 200 million tons of annual volume of traffic, it developed by 20000 tons of trains and special vehicles.

Of type C80 aluminum alloy coal in our country after the C76 steel tub gondola car body light 5 t, less C63A type gondola car light the 19 t, on the basis of the gross vehicle weight, greatly improving the vehicle load effectively. Because of type C80 aluminum alloy coal more C63A open wagon load type gondola car each 19 t, improve the load capacity 31.1%. As a result, the annual average revenue per car will increase 229200 yuan; In each vehicle service life period income will increase 5.729 million yuan; Can reduce vehicle ownership at the same time,

according to the 200 million tons of annual volume of traffic, can reduce the purchase of 3763 vehicles, to reduce locomotive purchase 165 units. Use of type C80 aluminum alloy coal gondola car can reduce the train logarithm, thus reducing the maintenance personnel, locomotive vehicle drivers, locomotive combustion fee, car maintenance fee, and line loss, workers achieve increase and efficiency improvement.

Rail passenger vehicles

With the traditional vehicle manufacturing materials weathering steel and stainless steel, aluminum can reduce 50% of body weight, on high-speed lines, curved lines, undulating lines and bad environment has a good adaptability, so they become city metro, high-speed railway and freight railway track vehicles of one of the optional materials. Currently aluminum subway in Tokyo and Shinkansen rail vehicle has been widely used, four types of railway passenger dedicated line in China the emu CRH1, CHR2, CRH3 and CRH5, besides CRH1 stainless steel material is qualitative, the rest of the three kinds of car body are aluminum alloy material, generally speaking more than 250 kilometers per hour of high-speed train are aluminum alloy material.

Has been widely used, the four kinds of railway passenger dedicated line the emu CRH1, CHR2, CRH3 and CRH5, besides CRH1 stainless steel material is qualitative, the rest of the three kinds of car body are aluminum alloy material, generally speaking more than 250 kilometers per hour of high-speed train are aluminum alloy material.

Civil aviation passenger plane lightweight design has become a trend

A century, no matter how the fuselage materials change, it is steadily in the direction of the high strength, lightweight. Especially in recent years, both strength and advantage of lightweight composite materials is at the speed of a kind of hard to imagine in the fuselage materials subject position. Airbus, for example, short decades, composite material proportion has accounted for more than half of the overall material plane.

In today's aerospace, lightweight and structure of "low consumption" is has always been a mohican. Generally speaking, we are familiar with automotive hundred kilometers fuel consumption often ranging from 5 to 12 l) (individual large displacement car beyond this range, even the F1 such gas-guzzling cars hundred kilometers fuel consumption is not more than 100 l.

Capable of carrying more than 400 of Boeing 747-400 as an example, its the biggest 216840 litres of fuel capacity, calculate by $100 a barrel, is $136000. The full range of 13000 km. On this scale, lightweight materials to reduce the oil to be reckoned with. According to iata, fuel costs about 26% of the total cost of the air. And in some domestic airlines, fuel costs even accounted for 40%. The United States in 787, Boeing aircraft development process, a $300 million funding research in aircraft parts of titanium alloy to replace aluminum alloy to solve the problem of overweight, so as to achieve the objectives of the weight 2500 kg. Once the goal implementation can reduce fuel consumption by 20%.

Second, the carbon fiber composite materials led light wave

One popular high strength and low density
Carbon fiber composite material is also called general CFRP, is English Carbon Fibre Reinforced Plastic, Chinese translation for the Carbon fiber Reinforced resin matrix composites, Carbon fiber composite materials for short.

Carbon fiber (CF, CarbonFiber) general with polyacrylonitrile (PAN) as raw material, first in 200 ~ 300 ℃ in air oxidation, then under inert gas protection complete carbide with the high temperature of 1000 ℃ or so, the last 1500 to 3000 ℃ heating into carbon fiber.

More than 90% of the carbon fibers is carbon atoms, and the quality is lighter than almost any other metal. In addition, due to the carbon molecules are arranged according to the fiber direction rules of two-dimensional reticular structure, and has strong features. According to the number of monofilament in carbon fiber tow, polyacrylonitrile based carbon fiber and can be divided into small tow (space) and large tow (industrial) two, monofilament number 1 k - 24 k carbon fiber were divided into small tow, while more than 48 k is divided into tow.

CFRP to denote made of carbon fiber and polymer resin composite carbon fiber composite material, epoxy resin CFRP its specific strength and modulus than the comprehensive index, is among the highest in the existing structure material. Strength of CFRP is generally in more than 1800 mpa, seven to nine times that of steel, and the specific strength of A3 steel was only about 59 mpa, than modulus also reached 300 gpa, general steel is only about 200 gpa, however, the density of CFRP is only 1/4 of general steel, this also is the important cause of the popular: high strength + low density.

2 lightweight carbon fibre and car

Lightweight is closely connected with the new material, electric light future mainly involves four materials: carbon fiber composite materials, aluminum alloy, magnesium alloy and high strength steel. The use of these materials, should from the cost, and the connection of the metal, repair and recovery comprehensive considerations.

Carbon fiber composites molding body because it is an organic whole, so it saves a lot of fasteners, fittings, welding materials and other accessory structure weight, so weight is not only the material itself, also reduced the additional weight, so the integration of carbon fiber composites forming technologies to reduce the of vehicle restart to the huge role.

In addition, tire lightweight is becoming a development trend of automobile lightweight, the future will be realized or mass production. It is understood that the wheels with epoxy resin structure CFRP (carbon fiber reinforced polymer) surrounding the aluminum alloy structure. Due to reduce weight, this kind of tyre can improve the vehicle's power, energy conservation and efficiency. Lightweight can tire vehicle frame lightweight double benefit, will become the mainstream in the future. Automotive lightweighting brought great power for the development of carbon wheels.

3 in the fields of frontier began to try

Carbon fiber composite materials compared to traditional metal materials, the biggest advantage is under the same strength can greatly reduce the structure weight. Made aircraft structures with CFRP and compared with aluminium alloy, the effect of weight loss of up to 20% - 20%, reflect the huge energy saving benefits. Industry expert analysis, the next 20 to 30 years, aviation composite materials will usher in a new development period, a wide range of application of CFRP, will bring revolutionary change aviation industry chain, including the innovation of the design concept, design of the designer's knowledge update, and the group of restructuring, the aviation supply chain strategic change, and put forward unprecedented challenges to the aviation maintenance.
Military applications

In the 1960 s, the United States will first CFRP used on military aircraft, used in door, flap, fairing, aileron and rudder force smaller or the bearing components. In the early 80 s, the development to the vertical tail, flat tail wing level of bearing parts, such as F - 15-16 F, F - 18, mirage 2000 and mirage 4000 adopts the composite wing, the dosage of composite materials co., LTD. By the end of the 80 s, the United States launched the fourth generation fighter F - 22, F - 35 JSF, composite materials begin to applied in the wings, fuselage and other main bearing structure, the structure of military aircraft composite process accelerate, increasing dosage of composite materials,

the dosage of the composite material has now account for 20% of the quality of military aircraft structure - 50%.

Some aircraft also adopted on the engine structure composite materials, the composite materials using high temperature resistant resin (polyimide) manufacturing, the working temperature can reach 250-250 ℃, used for engine cold end parts, mainly outside the engine bypass machine box, fan stator vane and rotor blade, machine box, engine nacelle and thrust reverser applied on the parts.

Commercial application of

Is not only the advantages of lightweight composite materials, and bring the design innovation, through the reasonable design, also can provide, such as fatigue, vibration resistance, corrosion resistance, durability and/through the wave absorption, and other traditional materials cannot achieve outstanding features, increase future development potential and space. Especially compared with the traditional materials such as aluminum alloy, composite materials using can obviously reduce maintenance requirements, reduce life cycle costs, especially when the plane after entering aging phase difference is more apparent.

At the same time, most of the composite aircraft component to the overall forming, greatly reduce the number of parts and fasteners, which reduce the structure quality, reduce the connection and assembly cost, and effectively reduce the total cost.

Two global aviation giant - the Boeing and Europe's airbus company many years of competition seems to be worse, one of the important performance is increasing the amount of composite material.

Relative to the military, commercial higher safety and reliability requirements. And as a new type of composite material structure, in the understanding of material properties, guarantee the stability of technological measures and the related experiment data is not very full, its development has experienced a relatively cautious and long history. The application of composite materials in aircraft from start to the main structure of the application, only more than 10 years; In the commercial application of beginning in the 1980 s to the wide range of applications, has experienced more than 30 years.

In the use of civil aircraft structure composite materials cap is about 60%. From 2011 to 2020, is expected to increase by 12400 general aviation aircraft, executive market will be increased by 13600. New flyer on the quality of the composite material proportion about 54%, accounting for 68% of executive. With the growing commercial demand for carbon fiber composite material, the next 20 to 30 years aviation composite materials will enter a new period of development.

Three, carbon fiber production process and main equipment

1 carbon fiber production of upstream and downstream industry chain
Carbon fiber industry chain upstream petrochemical industry, mainly through the refining of crude oil, such as cracking, ammonia oxidation process for acrylonitrile; Carbon fiber raw materials which enterprises through to give priority to with acrylonitrile polymerization generates polyacrylonitrile, in its spinning polyacrylonitrile precursor, preoxidation and carbonization of raw silk made of carbon fiber, through the processing of carbon fiber and the high quality resin for carbon fiber composite materials to meet the application requirements; Industry chain downstream enterprise design and development of carbon fiber composite materials and purchase of the application of carbon fiber composites structure.

Carbon fiber composites molding structure and material molding finish at the same time, the downstream product performance affected by fiber and resin matching and manufacturability is bigger, so must be developed by the original silk to carbon fiber composite material of the whole industry chain. The development of downstream products, research and development of carbon fiber to form a positive interaction process. In the production and application to improve, to improve, expand application stability "found problems in the circulation, solve the problem, from stable to stable gradually.

In carbon fiber in the whole industry chain, different stages of the product price has risen, the same variety of strand for about 40 yuan/kg, about 180 yuan/kg, carbon fiber presoak expected about 600 yuan/kg, civil composite materials about 1000 yuan/kg, auto composite materials about 3000 yuan/kg, aviation composite materials about 8000 yuan/kg, have substantial value-added processing of each level.

2 carbon fiber production of upstream and downstream industry chain

Carbon fiber production process mainly includes: drawing, drawing, steady, carbonization and graphitization.
Drawing: this is the first step in the process of producing carbon fiber, this process is a physical change, mainly raw materials to separate fiber forming process, in this process, spinning dope trickle and solidified liquid mass transfer, heat transfer, phase equilibrium between mobile. Lead to PAN strips of settling out form the gel structure.

Draft: general was conducted in 100-300 degrees Fahrenheit, according to the tensile effect of directional fiber, this process is to achieve high modulus of PAN fiber, Gao Jianghua, densification, and the key step in the refinement.

Stability: softening is often said. Through the 400 ℃ heating oxidation methods make thermoplastic PAN linear macromolecular chain into the plastic heat trapezoidal structure, make its not melt at high temperature, keep the fiber morphology, thermodynamics in a stable state.
Carbide: in the range of 1000-1000 degrees, the PAN African carbon away, finally produce carbon content more than 90% with a layer of graphite structure of carbon fiber.

Graphitization: in 2000-3000 degrees, the amorphous, layer structure of carbide material to the three-dimensional structure of graphitization, is the main technical measures to improve the carbon fiber modulus.

By on the production process of PAN precursor fiber strand, after a wire frame preliminary draft of damp and hot, and by drafting in turn into preoxidation furnace, after several sets of preoxidation furnace group of different gradient temperature field obtained after preoxidation fiber (panof silk); Panof successively into the medium temperature carbonization furnace and after high temperature carbonization furnace carbon fiber; The carbon fiber surface treatment after the final, sizing, drying process for carbon fiber products. The whole process of continuous wire walking, precise control, any procedure, some problems will affect the stability of the production and final quality of the carbon fiber products. Carbon fiber production process, technical key points, high barrier, is a multidisciplinary, multiple technology integration.
Precursor and carbon fiber main production equipment is mainly spinneret, steam drawing machine, winding unwinding device, high temperature carbonization furnace and graphitizing furnace, etc., some of the core basic dependence on imported equipment. Carbon fiber preparation process is the main problems existing in our country, some general equipment and process of matching is lower, and special equipment design and technical transformation of the lack of some necessary research and development support, the overall production level is relatively low, made of carbon fiber composite indicator coordination and control is not high. Domestic thousand tons equipment design, manufacture and operation of the lack of system integration capabilities, the domestic carbon fiber cost problem has not been solved effectively, and influence of carbon fiber industrialization.
The original wire equipment is introduced

In a typical 1000 t PAN based carbon fiber precursor production line of research and development, for example, simple equipment, components to be introduced. Annual output of 1 000 t PAN based carbon fiber precursor production line ChanYuanJi equipment including: spinning machine, drawing machine, drying machine and electrical control part.

1, spinning machine,

Touch screen is equipped with the main screen, operation control, parameter setting picture. Failure occurs when the field devices or electronic control equipment, touch screen can display failure, and start the alarm, through the touch screen operation, can be set and modified. The higher DCS requires data acquisition, processing and management, complete the real-time control and monitoring of frequency converter device on the spot.

6, preoxidation furnace equipment is introduced

At present, the common oxidation equipment are straight-line furnace, hot air circulation oven, external heated preoxidation furnace, fluidized bed type preoxidation furnace and diversion plate furnace type furnace. To guide plate preoxidation furnace as an example to introduce general equipment composition and the working process.

Preoxidation furnace hot air flow can run with fiber in parallel, can also be vertical. Hot wind flow when the speed of the parallel flow is not too high, reflecting the heat is not easy to instantaneous elimination; When traffic is too big, hot wind energy consumption; When the vertical flow, which is beneficial to reflect the hot out, but the parallel operation of the tow choke for hot air, the air stove and the more easily by preoxidation furnace throat opening into the furnace, make effectively reflect period shorter. Equipped with wind deflector preoxidation furnace structure as shown in figure, the hot air flow path into "of" glyph, many times through the fiber bundle, which can effectively take away heat of reaction, shorten the preoxidation time, walking wire speed is three times as many ordinary preoxidation furnace. But this kind of preoxidation furnace furnace structure is relatively complex, especially the concave and convex appear alternately guide plate, broken wires to process and equipment, including cleaning furnace chamber for daily use and follow-up work to bring great inconvenience, still need to further improve the design.

7, carbide furnace equipment

Low temperature carbonization furnace temperature of general design in 300-800 degrees, in the temperature range of the panof silk dramatic changes have taken place in structure, about 30% - 30% of the quality (as opposed to panof silk) pyrolysis runaway, is the key to the structure transformation stage.

Drafting will panof silk into the furnace, and in the heating furnace, ensure temperature respectively before and after the non-contact labyrinth seal, in addition to prevent the waste gas from escaping. The non-contact labyrinth seal is an essential device for carbide furnace, sealing effect directly affects the quality of carbon fiber. For ht magnitude of carbon fiber production line, run fibre above h beam, requirements within the carbonization furnace width and labyrinth seal the opening width is more than 1000 mm.

3 carbon fiber production of upstream and downstream industry chain

Carbon fiber related production equipment mainly from two aspects, on the one hand, is the production of carbon fiber strand equipment, on the other hand is a carbon fiber strand compressed into composite materials as well as the final parts molding equipment.

Some general equipment and technology in the process of preparation of carbon fiber in our country's match, the corresponding special equipment design and technical transformation of the lack of some necessary basic research support, special equipment manufacturing level is relatively low, the introduction and imitation become mainstream, made of carbon fiber composite indicator coordination and control is not high. At present, the drafting of spinneret, steam machine, winding unwinding device, such as high temperature carbonization furnace and graphitization furnace parts and equipment still rely on imports. Domestic thousand tons equipment design, manufacture and operation of the lack of system integration capabilities, the domestic carbon fiber cost problem has not been solved effectively, and influence of carbon fiber industrialization.

Most high-end carbon fiber is a small tow polyacrylonitrile (PAN) based carbon fiber. According to the international aviation, currently the world's main six small tow carbon fiber supplier's market share is: Japan toray company accounted for 35% 40%, toho company (23%), mitsubishi corporation (14%); Hershey's 12%, cyanide industrial companies in the United States accounted for 8%; The plastics industry in Taiwan and Britain SGL companies accounted for 3% to 3%. Japan three companies of the carbon fiber accounted for about 70% of the world - 80% market share, toray company production, product performance, the best is the world's largest carbon fiber supplier, on behalf of the Japan's highest technology level and research and development strength. Two companies in the United States market share of about 20%, including Hector's company has 40 years of development and application of carbon fiber for the U.S. military aircraft experience, can independently supply carbon fiber production, is the manufacturer of high modulus carbon fiber technology leader; Cyanide industrial company, with carbon fiber presoak follow-up products material is given priority to, carbon fiber products performance and research and development ability is lower than Hector. Taiwan's plastic industry company and SGL product performance is slightly lower than the level of Japan and the United States.

2014 global carbon fiber production has reached more than 60000 tons, industry control by Japan (about 70%), control market is Japan, the United States and the European Union (80%). Relying on its technical advantages and strong market monopoly, begin from 2005, Japan, the United States, France and other began to strictly control the carbon fiber, its exports to China for Chinese military scientific research and production of composite materials has caused serious difficulties. With the rise of China, Japan, the United States, Europe, the blockade and control of the carbon fiber technology to grow, and attempt to through price dumping and vicious competition means such as price, continue to implement extrusion and control of carbon fiber industry in China.

At present, the domestic T300 and T700 carbon fiber product preliminary achieved a number of applications in the field of national defense and national economy; Grade T800 carbon fiber has entered the stage of engineering scale application demonstration, and implements the batch production. But the above T800 and higher performance of carbon fiber market, production capacity in China is still unable to meet the domestic demand. In 2014, for example, in 2014 China's carbon fiber aggregate demand of about 15000 tons, accounting for 20% of global consumption, however, about 3200 tons, domestic production imported about 11700 tons.

In the future, with the continued development of the downstream industry, carbon fiber production gap will continue to expand in China, according to the gap of 11700 tons (2014) and the estimation of the annual production of 1000 tonnes per line, in the future at least 10 production lines added capacity is needed. Know about 2.6-400 million by according to the current price of a production line, the future vacancies domestic production capacity and market capacity of 26-4 billion. And corresponds to the downstream pressure molding equipment and material production of complete sets of equipment market space in demand after the release will be more big.
