迄今为止,人们已知的特种纤维有碳、硼、碳化物、硼碳化物纤维和以金属、合金和某些元素的氧化物为基础的纤维及某些其它纤维。然而,在众多的特种纤维中,碳纤维具有特殊的吸引力,它以举世无双的物理—机械性能,尤其是高比强和高模量,在特种纤维中独占鳌头。碳纤维不是金刚石,也不是石墨,是纤维状的碳材料,其化学组成中碳元素占总质量的90%以上。元素碳根据其原子结合方式的不同,可形成金刚石、石墨等结晶态,也可形 So far, special fibers are known as carbon, boron, carbide, boron carbide fibers and fibers based on oxides of metals, alloys and certain elements, as well as certain other fibers. However, among many specialty fibers, carbon fibers are particularly attractive because of their unique physico-mechanical properties, especially their high specific strength and high modulus. Carbon fiber is not diamond, nor graphite, is a fibrous carbon material, the chemical composition of carbon in the total mass of more than 90%. Elements of carbon atoms according to their different ways to form diamond, graphite and other crystalline state can also be shaped
