Breakthrough In China'S Carbon Fiber Technology To Break The Monopoly Of Foreign Technology

In addition to the continued development of self-reliance Carbon fiber industry There is no other choice. Carbon fiber reinforcement materials were first used in military products, and they are key technologies of technology intensive and politically sensitive. Because of the United States led Paris Coordinating Committee (COCOM), the embargo and blockade policy for socialist countries is advanced. Carbon fiber technology Still unable to bring in, especially high performance PAN based precursor technology, even if our country enters WTO, the situation has not changed much.

China started earlier in the field of carbon fiber research, but lagged behind the world advanced level in the field of production. It was not until around 2010 that China achieved stable large-scale industrial production of T300 grade carbon fiber. In 2011, China's T700 carbon fiber production line began trial production. The completion of the T800 production line further reduced the gap between China and the world's advanced carbon fiber production level.

Recently, a company in Jiangsu built China's first T800 carbon fiber industrialization line and made a series of products. Independent intellectual property rights innovation The result has broken the technological monopoly of foreign manufacturers. The first 25 ton T800 carbon fiber production line has achieved zero breakthroughs in the industrialization of high performance carbon fibers in China.

At present, domestic R & D and construction of 100 ton production level T800 carbon fiber production line are being carried out.

Carbon fiber is a special kind of special fiber composed of carbon. Its carbon content varies with different species, usually more than 90%. Carbon fiber has the characteristics of general carbon materials, such as high temperature resistance, friction resistance, conduction, heat conduction and corrosion resistance. However, unlike carbon materials, the carbon fiber has obvious anisotropy, softness, and can be processed into various fabrics, showing a high degree of strength along the fiber axis. Carbon fiber has a small specific gravity and therefore has a high specific strength.

With the development of China's carbon fiber technology, carbon fiber reinforcement materials will be more widely applied. High strength carbon fiber has wide application prospects and application requirements in the aerospace field, especially in all kinds of missiles, launch vehicles, spacecraft and stealth fighters.
