一、概述 碳纤维复合材料是六十年代发展起来的最有应用价值的新材料之一。这种复合材料的比强度和比弹性模量相当于金属钛的3倍和5倍,故极宜作为刚性和强度要求高而比重要求小的结构材料,例如应用在直升飞机结构件、宇航飞行器和深海受压容器等方面。碳纤维复合材料具有突出的性能,可满足很多要求。因此,它已受到人们极大的重视,并在应用技术方面取得了较大进展。但由于碳纤维,特别是 First, an overview of carbon fiber composite material is developed in the sixties the most valuable new material. The specific strength and modulus of elasticity of this composite material are equivalent to 3 times and 5 times that of titanium metal, so it is very suitable as a structural material requiring high rigidity and strength and small specific gravity, for example, in helicopter structural parts, aerospace Aircraft and deep sea pressure vessels and so on. Carbon fiber composites with outstanding performance, can meet many requirements. Therefore, it has received great attention of people and great progress has been made in application of technology. But because of carbon fiber, especially
