Development Status Of Carbon Fiber Industry: Relying On Application Terminal To Open New Version

< p > according to the relevant a href= "http://sjfzxm.com/news/index_z.asp" > market < /a > Research Institute figures, the demand for global carbon fiber market will remain 13% before 2015, and the demand for carbon fiber in China will increase faster than that of the world.

It is predicted that the total demand of carbon fiber will reach 16 thousand tons by 2015.

< /p >

Less than P, driven by demand growth, the development of domestic carbon fiber has accelerated in recent years and production capacity has been greatly improved.

At present, more than 30 enterprises in China have been engaged in R & D and production of carbon fiber, and their capacity has exceeded 20 thousand tons.

In addition, there are still a large number of carbon fiber production lines under construction and planning in China, but there are still many problems behind the domestic carbon fiber projects.

< /p >

< p > on the one hand, China's "a href=" http://sjfzxm.com/news/index_p.asp "less than /a per year" will cost huge sums of money to import more than 10000 tons of carbon fiber products to meet the needs of national economic development.

Data show that in 2013, China imported 12386.2 tons of carbon fiber and its products, an increase of 34.5% over the same period last year, and imports amounted to US $383 million.

On the other hand, China's carbon fiber enterprises are under construction, and the annual production of carbon fiber is less than 3000 tons, which only produces 1/10 of production capacity, and the mass production line is idle.

< /p >

< p > industry insiders say that the low utilization rate of domestic carbon fiber production line is not due to the lack of downstream market demand, but because it is difficult to produce qualified products.

Carbon fiber production process is complex, from polymerization, spinning, oxidation, carbonization, surface treatment, any production link problems, may affect the performance of carbon fiber.

"Most of the raw silk has high impurity content, poor quality stability, large coefficient of variation, no good raw materials, and how to produce good products." although China's carbon fiber production capacity has expanded rapidly in recent years, most of the products are relatively low quality products, and the gap is obvious compared with that of foreign countries. Therefore, the expansion of this capacity also aggravates the structural surplus of carbon fiber to a certain extent.

< /p >

< p > in addition, the current industrial development mode also hinders the application of domestic carbon fiber.

Foreign carbon fiber manufacturers have established extensive cooperative development and stable supply and demand relationship with manufacturers of important applications such as automobile, aerospace and other carbon fibers, and established a complete carbon fiber industry chain.

China's carbon fiber industry is disconnected from scientific research, production and application.

"Often after products are developed, they do not know what they can be applied to, and how they will be used.

< /p >

< p > from the application field, China's carbon fiber also needs to break through in its industrial application.

Taking acrylonitrile based carbon fibers, which account for more than 90% of carbon fiber production, for example, the proportion of industrial applications and sports leisure is 75.7% and 24.3% in the world, while in China, the proportion is 20% and 80% respectively.

In 2013, China imported 5931.6 tons of carbon fiber and its products for sports and leisure, accounting for 47.89%.

< /p >

< p > because of the particularity of the application field of carbon fiber reinforced plastics, the foreign countries have monopolized the blockade of high performance carbon fiber technology and high-end process equipment, dumping low-end carbon fiber products to China, adding to the small and scattered state of China's carbon fiber enterprises, the quality is not stable, and the production cost is higher than that of imported similar products, and the whole industry is in a state of loss.

< /p >

< p > < strong > find application breakthrough point < /strong > < /p >.

< p > in view of the current development of China's carbon fiber industry, besides the improvement of technology, the development of enterprises is very important. The key is to pinpoint the breakthrough point of application.

The application of carbon fiber composites, such as FRP in civil engineering, also explores a new path for the development of carbon fiber in China.

In addition, the other important application direction of carbon fiber is the ocean (seaport) environment, which can effectively solve the important problem of preventing seawater corrosion during the development process.

< /p >

< p > aiming at the current development of China's carbon fiber industry, Zhang Guoliang, chairman of Zhongfu divine eagle Carbon Fiber Co., Ltd., said that technology is not the most important issue at present, and the most important thing is to pass the market pass.

In addition to improving technology, the development of enterprises is also very important. The key is to identify breakthroughs in application.

Zhongfu Eagle carbon fiber company has made a lot of research in application, further improving the adaptability of the technology, and developing Carbon Fiber Cello, small UAV and other products in succession.

< /p >

Technological breakthroughs in the field of civil engineering can bring new opportunities for the application of carbon fiber. < p >

In January this year, the key technology of preparation and application of high performance fiber composites for civil engineering was awarded the two prize of the national science and technology progress award.

It is understood that high performance fiber reinforced polymer (FRP) has the advantages of light weight, high strength, corrosion resistance and design. It can significantly improve the performance of civil engineering structure and extend its service life.

The application of carbon fiber reinforced polymer (FRP) in civil engineering has also explored a new way for the development of carbon fiber application in China.

< /p >

< p > Yue Qingrui, President of the Institute of Architectural Research of China Metallurgical Industry, believes that carbon fiber has more prospects in the field of civil engineering compared with aviation, energy and sports leisure.

According to statistics, 40% of domestic carbon fiber is used for reinforcement and reinforcement each year, so it is an important application direction.

The project team has made a series of explorations on the application of carbon fiber in the civil engineering field, and developed products such as plate, reinforcement, cloth and so on.

At the same time, because carbon fiber is characterized by high strength and poor extensibility, Yueqing Rui and his team try to mix carbon fibers and other fibers to increase the elongation at break of materials.

Hybrid fiber can give full play to the advantages of different fibers, enhance strengths and circumvent weaknesses, and improve the structural elongation, energy dissipation capacity and deformation recovery ability.

< /p >

An important area of FRP such as P, carbon fiber and so on is structural reinforcement and pformation.

For example, the fiber mesh profile can be fixed on the surface of concrete components, and then jet or manual rubbing polymer cement mortar is integrated with the original concrete so as to improve the bearing capacity and durability of the structure.

< /p >

< p > another important application direction of carbon fiber is the marine environment.

At present, China is developing marine resources. Combining FRP with concrete can effectively solve the important problem of seawater corrosion in the development process.

< p > < strong > application driven development < /strong > < /p >

Less than p ago, the state mainly supported the production of carbon fiber products, and now it is more supportive of application development. It hopes to enlarge the application field and promote the development of production enterprises in turn.

< /p >

< p > < < a href= > http://sjfzxm.com/news/index_cj.as > > Industry > /a > problems. China's ideas of developing carbon fiber are changing.

< /p >

< p > October 2013, the Ministry of industry and Commerce issued the "accelerating the carbon fiber industry development plan of action".

The plan clearly states that China should adhere to the principle of combining industrial development with downstream applications in developing carbon fiber.

The plan puts forward the four major actions of key organizations, including the downstream application expansion action, and specifies the specific objectives and paths: first, to ensure the national major engineering needs.

Focusing on the performance requirements of high-end carbon fiber products in the fields of aerospace, military equipment and major infrastructure, we should establish an integrated upstream and downstream collaborative mechanism to ensure superior carbon fiber products with superior quality and stable quality.

The application of CFRP in key structural parts of civil aviation and aerospace field is completed, and airworthiness requirements are met.

Accelerate the demonstration application of carbon fiber composite materials in major infrastructures such as cross sea bridges, artificial islands and reefs.

< /p >

< p > secondly, expand the application in the industrial field.

Focusing on the needs of wind power generation, power pmission, oil and gas production, automobiles, pressure vessels and other fields, we support the application demonstration, and guide production enterprises, research and design institutions and application units to jointly develop various forms of carbon fiber reinforced composite materials, components and finished products, accelerate the cultivation and expansion of the application market in the industrial field, drive the pformation and upgrading of related industries, and ensure the development needs of strategic emerging industries.

< /p >

< p > again, enhance the ability to serve the people's livelihood.

We should increase the application scope of carbon fiber in the field of building reinforcement, increase the safety factor of buildings, continue to make bigger and stronger carbon fiber sports leisure products, meet the needs of people for cultural and sports life, and actively explore the application of carbon fiber products in the fields of safety protection, health care, energy saving and environmental protection, and constantly meet the needs of economic and social development.

< /p >

< p > "previous countries mainly support the production of carbon fiber products, and now they are more supportive of application development. They hope to enlarge the application field and promote the development of production enterprises in turn."

In this regard, industry insiders said that the correlation between the upstream and downstream industries of carbon fiber is very close. It is difficult for carbon fiber producers to complete the development of a new product downstream of carbon fiber.

Therefore, the government should give full play to the ability of coordination and allocation, and build a complete industrial chain with coordinated development of production, learning, research and application through alliances and other industry organizations.

At the same time, all supporting policies need to be formulated and put into place.

"If land, taxes, subsidies, electricity prices, scientific research and other policies can be implemented in time, the enthusiasm of enterprises for scientific research and innovation will be mobilized."
