The carbon fiber is one kind of new high performance textile fiber, the specific tenacity high, thermostable, bears the friction, anti-corrosive, widely applies in domains and so on aerospace, machinery, building materials transportation, literary style medical service, has the important strategic position in the national economy. In recent years along with the production technology advancement and the application scope's unceasing expansion, the carbon fiber demand expanded year by year. in 2007 about our country PAN base carbon fiber consumption quantity 6900 tons, forecast that in 2010 will amount to 8700 tons. Implement the carbon fiber technology and the product dual blockade influences the supply-demand relation and the developed country to our country, our country carbon fiber market have been at the condition which is under the control of others, even certain carbon fiber compound materials high-end user faced with does not have raw material to be possible to carry on the processing the awkward region. In addition, because large-scale aviation industrial and so on airplane manufacture and clean energy drawing, worldwide scale's carbon fiber demand will continue to increase, within the international carbon fiber supply and demand relations short-term will not recede largely. Therefore, takes the significant strategic material, our country must construct the foothold domestic carbon fiber independent support capabilities, guarantees the high-end user the need.
Our country carbon fiber research and development history started from the early-1960s, but more than 30 for years key technologies have not been able to break through, the domestic carbon fiber produced can with the technology and the overseas existence quite big disparity, this present situation hindered the national advanced weapon renewal, to pose the threat to the national security, also affected to the high added value's national economy pillar industry's development enormously. Restricts our country carbon fiber development the primary factor to have two aspects; first, carbon fiber original fibroin quantity question. The domestically produced original silk in the purity, the intensity as well as the homogenization aspect and overseas compares the existence big disparity, has restricted the domestically produced carbon fiber product quality greatly. Second, thermostable material and large-scale tower electric muffle furnace. The domestically produced carbide furnace uses can only allow in 1400℃ below the temperature use silicon carbide to take the heating element, under the high temperature environment the silicon carbide anti-load intensity is low, cannot manufacture the great size commercial scale carbide furnace, is unable realizes 1500℃ best craft. Overseas uses the high pure graphite material 1800℃ above high temperature carbide furnace strict limit to our country's export, moderate scale's high temperature carbide furnace imported price is high, causes the domestically produced carbon fiber installment the construction cost to be excessively high, is unable with to import the textile fiber competition.
In order to break the overseas technology and the product monopoly, met the domestic market need, chemical fiber profession some enterprises has further expanded the high performance carbon fiber investment, promoted our country carbon fiber industrialization process. If the Shanxi permanent day spinning and weaving new textile fiber science and technology Limited company constructed has yearly produced 1200 ton PAN base carbon fiber original silk to change the extension projects, the Lianyungang condor new material Limited company to construct has yearly produced 2500 ton polypropylene nitrile original silk 1000 ton carbon fiber projects, the Shandong Weihai light prestige Group 3K(1K) high performance carbon fiber and machine the fabric production line items of basic construction, at present these production lines have completed the production, altogether formed has yearly produced 40,000,000 ton polypropylene nitrile base carbon fiber original silk, 13,000,000 tons carbon fibers as well as 300,000 meter carbon fiber compound materials productivity, caused our country carbon fiber scale of production to step the kiloton new altitude.
These project's implementation caused our country high performance carbon fiber industrial production to realize the technological breakthrough, affected and has led other high technology and new technology textile fiber development, to satisfied our country military, the civil two market requirement, played the good demonstration lead role, because simultaneously the T300 level carbon fiber has realized the manufacture domestically, has broken the overseas monopoly, the force imported price large scale drop.
