复合材料在飞机和汽车上的应用动向(二)

复合材料大量用于航空航天工业和汽车工业，特别是先进碳纤维复合材料用于飞机尤为值得注意，不久前，碳纤维复合材料只能在军用飞机用作主结构，但是，由于技术发展的进步，先进复合材料已开始在民航客机上也应用作主结构，如机身、机翼等，在民航客机上使用复合材料的决定，只有波音公司和空车公司这样的拥有雄厚的人力、财力和胆识的大飞机制造公司才可能作出，至于汽车上，主要使用玻纤增强塑料(热固性和热塑性塑料)用作车身、发动机室内零部件、车顶和进气路管；碳纤维复合材料近年来也日益增多的用于汽车上，主要用作车身外板、车门、进气路管和活门盖等。

Composites applcations trends in aerospace and automobiles

Composites are used in aerospace and automotive industries in large, particularly, advanced carbon fiber reinforced plastics used in air crafts should be worthnotice. Not long ago, advanced carbon fiber composites were used in militry airplanes as primary structures; in recent years, as the technologies have made greal progresses in the development, are beginning to be used in primary aero structures such as fulage, wings in civil airliners. As for automobiles, most primary glass fiber reinforced plastics ( therset and therplastic plastics ) are used as body, under hood cover components, Valve cover, inlettakes. As technologies develop, in recent years, carbon fiber composites are also used in automobile, mainly as body panels, roof, door and inlettake, etc.
