China'S Carbon Fiber Industry Has A Clearer Direction And Path.

While P is a huge demand prospect, it is a grim reality that domestic carbon fiber manufacturers are generally losing money.

China's carbon fiber industry has long been independently researched and developed, breaking the blockade of foreign technology and equipment, and achieving preliminary results in the industrialization of carbon fiber.

However, at present, there are prominent problems in the whole industry, such as backward key technologies, lagging behind downstream applications, high production costs and weak market competitiveness. If we can not grasp the opportunities for development, China's carbon fiber industry will not go back in the face of the fierce development offensive of the international carbon fiber industry.

< /p >

At the end of last year, the State Ministry of industry and Commerce issued the "action plan for accelerating the development of the carbon fiber industry", so that China's carbon fiber industry in the key period of development has a more clear direction and path of development.

As soon as possible to break through the bottleneck and change the status quo, the carbon fiber industry will usher in a better tomorrow.

< p > June 28th, Zhongfu Eagle carbon fiber company held the ribbon cutting ceremony of "annual output of 3500 tons high-performance fiber" project.

According to its own mature dry spray wet spinning process and technical equipment advantages, Zhongfu Shen Ying company, on the basis of its original carbon fiber production capacity, continues to expand its production scale, and build three new carbon fiber production lines with an annual output of 3500 tons. It plans to complete construction and put into operation in 3 years, with a total investment of 1 billion yuan.

As a leading enterprise in carbon fiber production, the breakthrough in technology and industrialization of Zhongfu divine eagle also reflects the continuous upgrading of China's carbon fiber technology.

< /p >

< p > carbon fiber is a representative variety of high performance fibers. It is an indispensable strategic new material for national economy and national defense construction. Its application scope is broad, its technology content is high, its radiation is wide and its power is strong.

The forecast shows that the demand for carbon fiber is expected to expand by more than 15% per year.

It is estimated that 5 years later, the market will expand to more than 2 times.

By 2030, China's carbon fiber demand will reach 300 thousand ~50 million tons.

The rapid growth of market demand and the sense of mission for developing strategic emerging industries have enabled many enterprises to devote themselves to the research and production field of carbon fiber and catch up with the pace of developed countries.

After 2005, with the introduction of relevant supporting policies, the carbon fiber industry was on the fast track.

< /p >

At present, China has mastered the industrialized production technology of T300 grade carbon fiber, and basically grasped the industrialized production technology of T700 class P carbon fiber.

However, compared with the developed countries, there is still a gap between the stability, reliability and economy of the products, and the industrialization technology of high-end products is still blank.

The maturity and upgrading of carbon fiber technology is still a long way to go.

For more than 10 years, China's carbon fiber industry has made significant progress in key technologies, equipment, industrial production and downstream applications. Thousands of tons of industrial equipment have been built and put into operation, and initially established the pformation from raw silk, carbon fiber to < a href= "http:// www.91se91.com/news/index_c.asp" > composite material < /a > products and the whole industrial chain, and realized the pformation from scratch to P.

At present, China has developed leading enterprises such as Zhongfu Eagle Carbon Fiber Co., Ltd., Jiangsu Heng Shen Carbon Fiber Co., Ltd., Jilin chemical fiber carbon Valley Carbon Fiber Co., Ltd., and its carbon fiber production capacity reaches 2 million tons. P

China has initially formed the foundation of the carbon fiber industry, trained the team of skilled personnel, and has the capacity of large-scale industrialization.

< /p >

< p > Zhongfu divine eagle company is the only enterprise in the domestic market capable of mass production and large-scale production of T700 high-performance carbon fiber.

In 2010, Zhongfu Eagle launched the development of dry spray wet spinning technology.

After more than 3 years of technical tackling, we have tackled the key technical problems of homogenizing large polymerization kettle polymerization heat conduction system, stabilizing dry spray wet spinning air layer disturbance control, homogenizing coagulation bath forming, efficient steam drafting, and stabilizing pre oxidation carbonization of < a href= "http:// www.91se91.com/news/index_c.asp" > energy saving > /a >. In the second half of 2012, we achieved mass production of dry spray wet spinning T700 carbon fiber. In September 2013, the company passed the appraisal of scientific and technological achievements of "dry spray wet spinning GQ45 high-performance carbon fiber engineering key technology and equipment development", and the product performance index reached the level of similar products abroad.

In the same year, T700 high performance carbon fiber was listed as "national strategic innovation product".

< /p >

< p > the "annual output of 3500 tons of high performance carbon fiber" project launched by Zhongfu eagle is all high performance fiber produced by dry spray wet spinning process, such as T700, T800, etc., which is mainly used to meet the domestic high, fine, sharp and other fields.

After completion of the project, Zhongfu Condor will form 15000 tons per year of raw silk and 6000 tons of carbon fiber productivity per year. It is China's largest carbon fiber production base.

< /p >

< p > in June 13th not long ago, the Jilin carbon fiber industry technology innovation strategic alliance was set up and the opening ceremony of the high-tech industrial base of carbon fiber and products was held in Jilin.

The strategic alliance of Jilin carbon fiber industry technology innovation was initiated by Jilin chemical fiber company, and 36 carbon fiber enterprises, tertiary institutions and research institutes in Jilin participated.

The alliance is committed to building an effective mechanism for production, learning and research cooperation around the carbon fiber industry chain. It will jointly solve the technical bottlenecks restricting the development of the carbon fiber industry, accelerate the pfer and pformation of technological achievements among the alliances, and effectively improve the overall technical level of the carbon fiber industry.

< /p >

< p > Jilin's carbon fiber and products high tech characteristic industrial base has gathered 18 key enterprises such as Jilin chemical fiber group carbon Valley company, Jilin Fang Dajiang City carbon fiber company, Jilin hi-tech fiber Co., Ltd. and so on, forming a complete industrial chain of "carbon fiber precursor carbon fiber carbon fiber products" in China. The production capacity of carbon fiber precursor reaches 5400 tons / year, carbon fiber production capacity reaches 818 tons / year, carbon fiber product specifications range from 1K to 48K, production technology and product quality all rank the leading level in the country.

< /p >

< p > < strong > the gap is still < /strong > < /p >.

< p > China's carbon fiber technology diversification system construction is still not perfect, basically depends on two methyl sulfoxide precursor technology, other raw silk technology development is lagging behind.

In particular, the ability to reach production and the quality stability on the basis of production are in urgent need of tackling key problems.

The idea of product stability in Chinese enterprises deviates intentionally or unintentionally. In fact, the stability of product quality in production process can not be equal to the batch stability of products supplied to users.

< /p >

< p > despite the continuous progress of technology, the overall backward situation of China's carbon fiber production technology and equipment has not been fundamentally changed at present, and it can not meet all the needs of high-end fields such as national defense, military industry and aerospace.

< /p >

< p > Japan has a capacity of nearly 20 thousand tons in a single Dongli company, which is equal to the capacity of all more than 30 enterprises in China.

At present, domestic products can only produce stable T300 specifications, and high specification products such as T700 and T800 have just made breakthroughs. Some carbon fiber production enterprises are still doing research on engineering technology.

Japanese companies can produce products including T700, T800, T1000 and T1100.

Zhao Xiangdong, vice president of China Chemical Fiber Industry Association, admitted that China's carbon fiber industry has made rapid progress in recent years, but overall, it has not yet fully grasps the core technology of carbon fiber, and there is still a big gap from the level of industrialization with international competitiveness.

< /p >

< p > Xu Lianghua, director of the National Center for carbon fiber engineering and technology research at Beijing University of Chemical Technology, believes that, in general, the construction of the diversified system of carbon fiber technology in China is still not perfect. At present, the research and development of the localization of carbon fiber and the industrialization of technology depend on the technology of two methyl sulfoxide, and the development of other raw silk technology is lagging behind.

The domestic carbon fiber has not been serialized in varieties, specifications and models, and there is a lack of high-end products.

< /p >

< p > Xu Lianghua thinks that although the T300 grade carbon fiber of our country has established the scale of industrialization, the stability and reliability of the products need to be further improved.

He pointed out that the concept of product stability in Chinese enterprises deviated intentionally or unintentionally. In fact, the stability of product quality in production process can not be equal to the batch stability of products provided to users.

The quality of products of different batches is quite different, which has an impact on users.

T700 grade new generation of high-strength carbon fiber engineering technology has achieved a breakthrough. However, there is still a gap between the overall scale and product performance and the international advanced level. The engineering or industrialization technology of T800 grade high strength medium die and basic high modulus and MJ high modulus and high strength carbon fiber is still blank, and the key technologies for its industrial production are urgently needed to break through.

< /p >

< p > < strong > Applied traction < /strong > < /p >.

< p > in analyzing the main factors that restrict the upgrading of China's carbon fiber technology at present, Xu Lianghua pointed out that the engineering construction of domestic carbon fiber produced by process imitation led to the weak capability of independent research and development of carbon fiber in China.

The main technology of the two methyl sulfoxide precursor has not been substantially improved and upgraded over the past 10 years. The same process gene has led to common problems in the technology and quality of domestic carbon fiber.

< /p >

< p > on the other hand, due to the lack of deep research on technology, the design guidance for localization equipment is relatively weak, the coordination level of equipment and technology is low, resulting in low capacity release capability, high energy consumption, poor operation stability and short life cycle.

The relatively backward equipment technology also leads to poor product performance stability, high production cost and the overall competitive advantage of the industry.

< /p >

< p > in addition, the joint operation mechanism of the industry university research institute is not running smoothly, and the lack of strength in technological research and development has led to the low efficiency of key technology and deep process problem solving, which has affected the rapid upgrading of the technology maturity of the carbon fiber manufacturing industry.

< /p >

< p > Xu Lianghua believes that from the perspective of the carbon fiber industry chain, the traction effect of the downstream carbon fiber composite materials on domestic carbon fiber is insufficient.

Due to the low maturity of China's carbon fiber industrialization technology, it is possible for the composite application units to resume the use of imported carbon fiber after completing the national project task.

In this way, carbon fiber enterprises will lose the opportunity of "social practice" of technology and products.

< /p >

< p > to solve these problems, Xu Lianghua put forward that we should lay stress on the key points, take different aspects of the process characteristics into consideration, and develop and perfect the technical system of R & D and Engineering Research of carbon fibers and composites in China.

The upgrading of carbon fiber quality depends on national defense and military traction. Industrialization technology upgrading should rely on the wide application of the national economy, and establish an enterprise oriented innovation system. According to the technical characteristics of carbon fiber preparation, we should rationally develop regional development and industrial chain development mode.

Develop two or more than two different solvent route of carbon fiber precursor preparation process, and form a diversified technical system of carbon fiber preparation.

To achieve high strength, high strength medium modulus and high modulus, high strength and other main series of carbon fiber preparation and engineering technology breakthrough, product realization engineering application.

Nurturing 3~4 furniture with potential for sustainable development of economy, technology and talent will enable enterprises to achieve multi variety and multiple series of carbon fiber production technology integration, diversify varieties, scale production capacity, and enhance competitiveness and risk tolerance of enterprises.

The construction of carbon fiber in different fields of demonstration and application projects, carbon fiber preparation technology and the application of market demand combined with traction, forming a benign development trend of technology and industry.

< /p >

< p > Zhu Bo, director of the carbon fiber composites research and development center of Shandong University, also said that the industrialization process of carbon fiber is a long industrial chain and technology chain. In engineering, it involves many links and many key problems. We should break through and upgrade the localization of equipment, system planning and design, process equipment integration, innovation and development of new technology, reduce production costs, and composite materials series development, and do well in seamless connection between technology research and development and production application.

At present, the engineering of carbon fiber in China needs market orientation, state support, enterprise investment and scientific research support. However, as long as we continue to push forward, we will definitely promote and apply it.
