航空航天材料發(fā)展現(xiàn)狀及前景

A review ofaerospace materia

  • 摘要: 文章較系統(tǒng)地介紹了航空航天材料的特點、地位和作用，結(jié)合具體案例分析了鋁合金、鈦合金、先進復合材料等結(jié)構(gòu)材料，以及以透波復合材料、吸波隱身復合材料為代表的航空功能材料和以防熱耐燒蝕復合材料、梯度功能復合材料為代表的航天功能材料的性能和應(yīng)用，指出航空航天材料的未來發(fā)展方向是高性能、多功能、復合化、智能化、整體化、多維化和低成本化。

     

    Abstract: 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.
