Carbon fiber composite material strength to reach the level of the steel, the proportion is one 5 of the steel.Therefore, the carbon fiber is considered to be most potential of auto lightweight materials.
Shi-cheng jiang said, however, China's carbon fiber application technology no breakthrough for a long time, the cost of materials and the manufacturing cost is high, can't mass production.
According to statistics, the global carbon fibre production capacity 128000 tons, of which China's carbon fibre production capacity of 15000 tons, output 4000 tons;Carbon fiber in our country has more than 30 companies, operating at only 20%.
Donghua university professor yu wood fire found in the research: companies generally small scale, weak anti-risk ability, coupled with price cuts by foreign enterprises, most enterprises loss, thus affecting the stable quality and operation cost.
Yu wood fire at the same time, points out that our country invests in high performance fiber research and development by leaps and bounds."Almost all chasing foreign products in the 1970 s to 90 s, when our country can transcend abroad?"
Throughout the international, the rapid development of the high-performance carbon fiber, a lot of other disciplines such as nanotechnology, chemical synthesis and condensed matter physics achievement has been applied in the development of high performance fiber manufacturing.
"High performance fiber industry, especially the carbon fiber is high quality, low cost, large scale, is the key direction we support, support some projects over the years, but I haven't find a breakthrough."Deputy director general of ministry of industry and consumer goods industry department xue-jun cao hope, during the period of "much starker choices-and graver consequences-in", high-performance fiber can from substantive breakthrough in terms of performance and application.
