1碳纤维的优良性能碳纤维是一种碳含量超过90%的纤维状炭材料,是以有机纤维——聚丙烯晴(PAN)纤维、粘胶纤维、沥青纤维等原丝经过预氧化、碳化、石墨化等高温固相反应工艺过程制备而成,由有择优取向的石墨微晶构成,因而具有很高的强度和弹性模量(刚性)。它的比重一般为1.70～1
1 excellent performance of carbon fiber Carbon fiber is a carbon content of more than 90% of the fibrous carbon material is based on organic fiber - Polypropylene Fine (PAN) fiber, viscose fiber, asphalt fiber and other raw silk pre-oxidation, carbonation, graphite And other high-temperature solid-state reaction process prepared from the preferred orientation of graphite microcrystalline structure, which has a high strength and elastic modulus (rigidity). Its proportion is generally 1.70 ~ 1
