随着航空工业的发展,对飞机结构材料的要求也越来越高。碳纤维复合材料具有强度高、弹性模量高、比重小的特点,同时具有线膨胀系数小,内阻尼大,减振性好,耐疲劳等优点。是一种有前途的新型航空结构材料。近十年来引起了人们的重视,这方面的工作国外有了较大的进展,已在飞机上应用。国内已有不少单位正在研制这种新材料,并在航空零部件的研制上做了一些工作,取得了一定的成绩。 With the development of the aviation industry, the requirements for aircraft structural materials are also getting higher and higher. Carbon fiber composite materials with high strength, high modulus of elasticity, the proportion of small features, with a small linear expansion coefficient, damping large, good damping, fatigue resistance and so on. Is a promising new aviation structural materials. Over the past decade has aroused people’s attention, work in this area has made great progress abroad, has been applied in the plane. Many domestic units have been developing this new material and have done some work in the development of aviation components and achieved some success.
