摘要
文章较系统地介绍了航空航天材料的特点、地位和作用,结合具体案例分析了铝合金、钛合金、先进复合材料等结构材料,以及以透波复合材料、吸波隐身复合材料为代表的航空功能材料和以防热耐烧蚀复合材料、梯度功能复合材料为代表的航天功能材料的性能和应用,指出航空航天材料的未来发展方向是高性能、多功能、复合化、智能化、整体化、多维化和低成本化。
This paper reviews advanced aerospace materials, focusing on their role and features. The performances and the applications of aerospace materials are discussed with examples, including the structural materials （aluminum alloy, titanium alloy, advanced composite）, the aeronautical functional materials （wave-transmitting composite, wave-absorbing stealthy composite）, the astronautical functional materials （ablative thermal protection composite, functional gradient composite）. It is pointed out that the development trends of aerospace materials are in the directions of high performance, compounding, intelligent, and low cost.
