由于宇航工程的迅速发展,对于减轻重量和防热的要求日益苛刻,因而要求一种材料兼备优异的结构性能和防热性能的呼声越来越高,到七十年代后半期,各种强度高、模量高、重量轻而又耐高温的陶瓷纤维相继问世,纤维增强复合材料又进入了一个更新的发展阶段。继日本的矢岛圣使教授1975年发明碳化硅纤维之后,又出现了氧化铝连续纤维、氧化锆连续纤维以及氧化铝硼、氧化铝钛连续纤维等。在八十年代,对于复合材料工作者来说,可供选择作为增强纤维的范
Due to the rapid development of aerospace engineering, the requirements for weight reduction and heat protection have become more and more stringent. Therefore, there is a growing demand for a material that combines excellent structural and thermal performance. By the second half of the seventies, all kinds of high strength , High modulus, light weight and high temperature ceramic fiber have come out one after another, fiber reinforced composites has entered a newer stage of development. Following Japan’s Professor Yajima instructor invented in 1975, silicon carbide fibers, followed by the emergence of alumina continuous fibers, zirconia continuous fibers and aluminum oxide boron, aluminum titanium continuous fibers. In the eighties, for composite workers, the choice of fiber as a reinforcement
