Carbon fiber is used with resin, metal and ceramic matrix composite, made of structural materials. Carbon fiber reinforced epoxy resin composite materials, comprehensive indexes of its strength, modulus, is the highest in the existing structural materials. Density, rigidity, weight, fatigue and other areas where there are strict requirements, at the request of high temperature, chemical stability of carbon fiber composites are an advantage. Carbon fiber is the early 50 rockets, aerospace and aviation needs to produce cutting-edge science and technology, now widely used in sports equipment, textiles, chemicals, machinery and medical fields. With cutting-edge technology on the properties of new materials are increasingly demanding, promote scientific and technological workers to try to improve. The early 80 's, high performance and ultra high performance carbon fibers have appeared, it is a leap in technology, also marked the research and production of carbon fiber has entered a higher stage.
