Carbon Fiber &Nbsp; Get Out Of The Way Of Low End Breakout (1)

A few days ago, Jiangsu Lianyungang Eagle Eagle Bicycle Co., Ltd. produced only 6 kilograms of carbon fiber bicycle with independent intellectual property rights. Its main raw material carbon fiber is provided by Zhongfu divine eagle carbon fiber limited liability company.

This bicycle has passed the European carbon fiber bicycle quality certification, the price is only the same kind of imported carbon fiber bicycle 1/3.

The first phase of the company's annual production of 100 thousand carbon fiber bicycles will start construction in the year.

Compared with ordinary bicycle, carbon fiber bicycle has the characteristics of light weight, durability and energy saving.

As a bicycle body material, this is only a small example in the field of carbon fiber application.

Due to its high strength, high modulus, high temperature resistance, corrosion resistance, electrical conductivity and thermal conductivity, carbon fiber has become a new chemical material with two characteristics, namely carbon material, strong tensile strength and fiber softness and workability. It is a new generation of reinforced fiber.

At present, carbon fiber is not only widely used in aerospace and military industry, but also has huge application space in automotive components, wind turbine blades, nuclear power, oil drilling, sporting goods, carbon fiber composite core cables and building reinforcement materials.

Dilemma 1:

Since the application of carbon fiber is related to national defense and military industry, the technology and production equipment of carbon fiber are strictly confidential.

Japan, the United States and other major production companies have long been highly confidential and unwilling to pfer high performance special raw silk production technology, nor do they sell high performance special precursor products, and the possibility of complete technology introduction is also very small.

According to He Fu, a researcher at Shanxi Institute of coal chemistry, Chinese Academy of Sciences, China has made breakthrough progress in the T300 general level industrialization. The 100 ton and 1000 ton carbon fibers have been put into production. The T700 level is undergoing pilot scale enlargement, and the T800 level is being developed in the laboratory.

At present, the quality of products of one or two units in China has exceeded T300 level performance index, reaching T400 level, and can be produced in small quantities.

This is in the 80s Japan Dongli company's carbon fiber research and development level.

Judging from the overall situation, China is currently in the pition period from T300 general level to high-performance T700 and T800.

But because of

Predicament two: small scale, quantity and multiple R & D

Our research on carbon fiber is not very late. Although some progress has been made, it has been developing slowly over the years.

According to Qian Bao Zhang Gao, founder of Jin Du energy and chemical engineering studio of Shanghai Qing Du information technology company, China started the research on PAN based carbon fiber in 1960s by the Institute of Applied Chemistry of the Chinese Academy of Sciences since 1960s, and a continuous pilot plant was completed in early 70s.

Later, the Shanghai synthetic fiber research institute, the Shanxi coalification Institute of the Chinese Academy of Sciences, Beijing University of Chemical Technology and Shandong Polytechnic University also began their research work, and passed the pilot test in the middle of 80s, and entered the industrialization trial production stage. A pilot plant with an annual output of several hundred kilograms to several tons and a pilot plant with an annual output of tens of tons were successively built.

But generally speaking, there is a big gap between the advanced level of technology and the level of production and quality.

Since entering the twenty-first Century, the domestic carbon fiber industry has developed rapidly. Anhui Hua Wan carbon fiber company first introduced the annual production capacity of 500 tons of raw silk and 200 tons of PAN based carbon fiber production equipment, and successfully filled the gaps in the industrialization production of China's carbon fiber and raw silk industry.

Since the beginning of 2000, China's carbon fiber has been diversifying towards technology, abandoning the original manufacturing technology of nitric acid precursor, and using one step wet spinning technology with two methyl sulfoxide as solvent.

At present, a small number of domestic carbon fiber products developed by independent technology have reached the level of international similar products.

According to Qian Bozhang, in recent years, the relevant ministries and commissions of the state have taken the industrialization process of carbon fiber technology as a strategic task of our country.

Subsequently, some enterprises successively joined the ranks of carbon fiber production.

At present, China has made Jilin Shenzhou carbon fiber company, Shandong Tiantai new material Limited by Share Ltd, Zhejiang Jiaxing Zhong Bao Carbon Fiber Co., Ltd., Baoding Swan chemical fiber group, Dalian Xingke Carbon Fiber Co., Ltd., Shanxi Heng Tian Textile New Fiber Technology Co., Ltd. and other production patterns of different sizes of carbon fiber manufacturers, the total annual production capacity is 2310 tons.

According to incomplete statistics, at present, there are 11 carbon fiber production enterprises under construction and construction. The total production capacity is 7100 tons of raw silk per year and 1560 tons of carbon fiber, of which 4 are under construction, and the total production capacity is 1100 tons of raw silk per year and 470 tons of carbon fiber.

In view of the complexity of the production process of carbon fiber, there are no more than 12 enterprises in the world.

They are Japan's Dongli, Toho and MITSUBISHI Liyang, Cytec, Hexcel, Hexcel, Zoltek, Amoco, SGL, Korea, Taiwan, Taiwan and so on.

Leading manufacturers include Japan's MITSUBISHI Liyang, Toho and Dongli, as well as Cytec, Hexcel and so on.
