进入八十年代以来,利用材料轻量化来节约燃料费用已成为飞机工业的主要趋势。飞机上用的复合材料一般为纤维增强的树脂复合材料。纤维中,尤以碳纤维与芳族聚酰胺纤维为优。合成树脂中,常温下使用的以环氧树脂为代表,高温下使用的有聚酰亚胺及聚砜等。本文主要对飞机用复合材料的发展前途进行一下探讨。在美、西德、法、英、荷兰及日本等国,军用飞机和民用飞机都竞相采用新的复 Since the 1980s, the use of lightweight materials to save fuel costs has become a major trend in the aircraft industry. Composite materials used on aircraft are generally fiber-reinforced resin composites. Fibers, especially carbon fibers and aramid fibers are preferred. Synthetic resins, used at room temperature as the representative of the epoxy resin, high temperature use of polyimide and polysulfone. This article mainly discusses the future development of aircraft composite materials. In the United States, West Germany, France, Britain, the Netherlands and Japan and other countries, military aircraft and civilian aircraft are competing to adopt a new complex
