Li zhong, deputy party secretary of the China chemical industry information center, said that China's carbon fiber and its composites industry chain is accelerating, the preliminary construction of the industry-university-research system, downstream application is starting.Industry has successively broke the T700, T800 thousand tons of high performance fiber industrialization, independent research and development of jilin chemical fiber 48 k large tow carbon fiber strand by carbonization and continuous mass production smoothly, and carbonization effect than expected, the indicators are surpassed Japan toray T300 level product level, for the domestic carbon fiber in the automotive, rail transportation, wind-power blades offers support in areas such as widely used.
According to xu jian, a researcher at the institute of chemistry of the Chinese academy of sciences and a distinguished professor at shenzhen university, the development of carbon fiber in China started in 1962 and has gone through several generations of scientists' efforts to gradually break through a series of neck jamming technologies.At present, the theoretical capacity of China's 24 carbon fiber enterprises with more than engineering capacity exceeds 23,810 tons, about 18% of the global total.In 2017, the output of domestic carbon fiber reached more than 7,000 tons (2018 data roughly maintained the value), and the total demand during the same period reached 22,000 tons, about two-thirds of which relied on imports.
Compared with Japan and the United States, China's carbon fiber and composite materials are still in the catch-up stage, and key technologies and equipment are still under control, li said.Lack of upstream and downstream collaborative innovation, downstream composite enterprises dare not use, can not use the situation has not been significantly improved.This seriously restricts the development of domestic carbon fiber industry.
Li hongyun, deputy general manager of cnac composite materials co., LTD, said that in recent years, China's large-scale investment in carbon fiber and composite materials in civil aviation, automobile and other transportation fields has not reached the expected output and benefits, and enterprises are in trouble.The industrial maturity of advanced composite materials for large-scale application in civil aviation, high-speed rail, automobile and other transportation fields is very low, most of the products are still in the laboratory and engineering verification stage, the new market has not yet formed, and the industrial maturity is in the embryonic stage.Still need to continue to break through the key technology and maturity.
Xu jian believes that under the new generation of carbon fiber system, enterprises should seriously consider how to reduce costs and improve carbon efficiency.He predicted that by 2020, with the progress of preparation, characterization and composite technology of high performance fiber and matrix materials and the breakthrough of key technologies, China's high performance fiber and composite materials will basically synchronize with the international advanced level and achieve high performance, high efficiency and high stability.By 2035, China will lead the world in terms of scientific basis and technological level in the field of high-performance fiber and composite materials. Only by mastering the technology of carbon fiber in our own hands and becoming the "huawei" in the industry can we not be afraid of the "strangled neck" of other countries.
Li hongyun suggested that enterprises should sum up experience, see the way forward clearly, find out the correct positioning, concentrate on tackling key problems, coordination up and down, resonance industry;The government should continue to increase its support to the industry and create better policies, market environment and financing environment.Investors should choose the enterprises and research institutions that really promote industrial development to make investment, and gain value through multiple rounds of investment iteration in the process of promoting industrial development, so as to avoid excessive greed, seeking for greater development, and blind investment across industrial development rules and stages.
