Carbon fiber is widely used in civilian, military, construction, chemical, industrial, aerospace and super sports car. Carbon fiber can be processed into fabrics, carpets, seats, ribbons, paper and other materials. In addition to the traditional use of carbon fiber is used as insulation material, it is generally not used alone, and more as a reinforcing material added to the resin, metal, ceramics, concrete and other materials constituting the composite material. Carbon fiber reinforced composite material can be used as aircraft structural materials, electromagnetic shielding materials in addition to electricity, artificial ligaments and other physical and alternative materials for the manufacture of rocket casing, motor boats, industrial robots, automotive leaf spring and the drive shaft and so on. About 1994 to 2002, with the carbon fiber spun from academic research to the filament carbon fiber, carbon fiber heating material production technology and products have gradually entered the military and civilian fields. China has been using carbon fiber filament National Grid cable multiple use cases. Carbon fiber is a new dual-use materials, technology-intensive and politically sensitive key material. Previously, the US-led COCOM (COCOM), the then socialist countries embargo embargo policy, in March 1994, COCOM although disbanded, but the embargo blockade shadow still hung over, advanced carbon fiber technology still lead not come in, especially high-performance PAN-based raw silk technology, even if China entered the WTO, the situation will not change much. Therefore, in addition to people to continue to be self-reliant development of carbon fiber industry, but no other choice. Therefore, foreign countries, especially the export of carbon fiber production technology leader in Japan and South Korea and other countries on China's carbon fiber materials and products has remained fairly cautious, only a small number of Chinese enterprises to establish its cooperative relationship with import channels for their products.
