新的思路 新的材料

New Thinking and New Materials

展望未来3O年,到下一世纪20年代末、3O年代初,航空产品在信息技术、材料技术及生物技术等新技术革命的推动下,性能将会上一个新的台阶,产品质量将会发生质的飞跃.其标志是以第五代战斗机、高速民用运输机以及单或双级入轨的空天飞机等为代表的新一代航空器的出现.新的要求据分析,第五代战斗机将于2020年前后上天,该机种有超大迎角,能以M2.5的速度高速巡航,具有自适应智能结构、较高的损伤容限、良好的抗损性.并且能满足长寿命。

This article forecasts material development of aerospace in the future 30 years. It points out that the emphasis should be placed on functional materials. Intelligent processing of materials (IPM) is the critical means to overcome the barriers in the material development. Nanostructure processing will revolutionize material developments. Improvement of materials properties may be based on biotechnology. Finally, features of material characterization and testing technology are also addressed.
