China carbon fiber technology breakthroughs can be used for advanced fighter

: Carbon fiber is an excellent physical properties of materials that can withstand high temperatures without losing strength , general acid, alkali has good corrosion resistance , widely used in aviation , aerospace and defense industry and other areas , known as the Industrial circles "black gold because of its particularity , the production technology during the Cold War are technology-intensive and politically sensitive strategic resources , COCOM that time the US-led embargo socialist camp after the end of the Cold War , because high-tech carbon fiber , high profits , the Western countries are still embargo on China , especially in the polyacrylonitrile (PAN) precursor production technology imports, even though China's accession to the WTO , there is not much change in a long time , foreign technology and products blockade embargo , China's demand for defense industry and aviation industry related materials are often caught in the " bricks without straw " situation , a number of defense projects needed to get even carbon fiber material through special channels .

Since carbon fiber is the national economy and national defense construction indispensable strategic new material , carbon fiber industry over a long period of independent research , breaking the blockade of foreign technology and equipment , the carbon fiber industry achieved initial results. Ten years, a special high -quality carbon fiber material used in aerospace, military and other fields has been highly concerned about our government , the industrialization of carbon fiber to be included in the national "863 ", " 973 " program, the NDRC, the Ministry of Science , the Ministry of other departments have also increased the carbon fiber industry support efforts. National "five " new materials industry development plan will focus on the development of carbon fiber as projects. Under the national policy support , China's carbon fiber industry have made ​​significant progress in key technologies , equipment , industrial production and downstream applications , T300, T700 kiloton industrialization device gradually built and put into operation, initially established from the precursor, carbon fiber to composite materials and the whole industry chain , to achieve the transformation from scratch .Wholesale masking tape


With continuous investment and efforts in recent years , the industrial development of carbon fiber into the blowout of our present, our country has been built or will be put to use T300 grade carbon fiber material for commercial production line for more than ten , currently some companies also plans expansion . As the basic production equipment and technology based on domestic , China's T300 grade carbon fiber material to meet the basic needs of military and civilian use , present , 3K, 6K, 12K and 24K tow the development of military and civilian products very quickly . At present, the total capacity of the T300 grade carbon fiber material generally about 1.9 to 22,000 tons , the total production capacity has reached the world.

Since 2007, domestic military carbon fiber materials have been widely used in the field of army new equipment , such as AVIC Shenyang Aircraft Company to develop and produce the F- 11B and J- 11BS fighter has been widely used in domestic military vertical tail parts made ​​of carbon fiber material . Straight army straight 10 and 19 armed helicopters extensive use of carbon fiber materials by the domestic military production fuselage frame structure, helicopter rotor , tail wing skins and helicopter parts . Army new generation of intercontinental ballistic missiles - Dongfeng -41 and waves two have adopted the domestic production of carbon fiber materials missile casing . Generally speaking , at present, our military carbon fiber material shortages and " strangle hold" the fundamental problem has been alleviated , the main direction of work is to promote the stability of product quality and improve processes.Masking tape


Since 2011 , China's T700 -level military carbon fiber material production technology has matured, ZhongFuShenYing 's T700 production line is currently the world 's third use of carbon fiber dry jet wet commercial production line spinning process system, has important strategic significance. At present, construction , completion and planned T700 grade carbon fiber material production capacity of about 20,000 tons . In 2012, our country will invest 2.5 billion yuan to build the first stage of T800 carbon fiber production lines, and to achieve a stable production , breaking the high-performance carbon fibers developed for key equipment and technology bottlenecks in the development and production of the blockade and monopoly , to fill the high-performance carbon fiber blank . Up to now, our country 's first T800 grade carbon fiber production line performance has met or exceeded the Toray company level.Washi tape


At present , China has started construction work kiloton T800 carbon fiber production line , full production planned in 2015 . 2020 , China's annual carbon fiber production will reach 5.5 to 70,000 tons , will be built kiloton T1000 carbon fiber production line and 100-ton MJ series carbon fiber production lines and can carry T1200 and M70J and other more complex high-performance fibers and special materials research and industrialization . By 2020, China 's carbon fiber technology will considerably with Japan, the U.S., Germany three main carbon fiber technology powerhouse.Sellotape
