碳纤维是一种具有优良性能的新型纤维。它不仅强度高、重量轻、弹性模量高而且具有耐高温、耐腐蚀、反射中子射线能力强等优点。碳纤维的出现是材料科学史上一个飞跃,它为工业生产和科学技术上的新工艺、新技术的建立提供了优异材料。三向编织的碳纤维复合材料比其它复合材料具有更突出的性能,因此已广泛地应用到航天、火箭导弹及电机工业等各个领域。 Carbon fiber is a new type of fiber with excellent properties. It is not only high strength, light weight, high modulus of elasticity and high temperature resistance, corrosion resistance, strong ability to reflect neutron radiation. The emergence of carbon fiber is a leap in the history of materials science, which provides excellent materials for industrial production and the establishment of new technologies and new technologies in science and technology. Three-directional braided carbon fiber composite has more outstanding performance than other composite materials, it has been widely used in aerospace, rockets and missiles and motor industry and other fields.
