现代交通与冶金材料

复合材料在国内外大飞机上的应用趋于广泛，先进复合材料应用与商用飞机技术发展密不可分，其在推进商用飞机发展和更新换代的同时，复合材料技术和制造装备本身也在不断升级，两者相辅相成。国产大飞机起步较晚，在复合材料应用上基本处于追赶趋势，但是随着国产复合材料的迅速发展，商用大飞机加快实现了关键部件的装机应用，并在发展中不断创新。

Composite materials are widely used in large aircrafts at home and abroad, and the application of advanced composite materials is inseparable from the development of commercial aircrafts.While promoting the development and upgrading of commercial aircrafts, composite materials technology and manufacturing equipment are also constantly updating. Chinese large aircrafts started late such that the application of composite materials is basically catching up with the international trend. With the rapid development of composite materials, however, commercial large aircrafts have accelerated the application process of key components, and continue to gain innovation in the development.
