中文摘要：

高超声速武器是军事装备的发展方向,在未来战争中起着重要作用。轻质材料是高超声速飞行器设计与制造的关键技术之一,它是实现高超声速飞行器高超声速、高机动性、远程打击等性能的基础和保障。高超声速飞行器轻质材料主要有蜂窝材料、泡沫金属材料、点阵材料。这些材料具有超轻、高比强、高比刚度、高强韧、高能量吸收等优良机械性能,以及减震、散热、吸声、电磁屏蔽等特殊性质,它兼具功能和结构双重作用,是一种性能优异的多功能材料。本文从材料制备、结构设计、力学与物理性能表征等方面综述了高超声速飞行器轻质材料的研究与应用现状,比较了三种轻质材料的机械和物理性能,重点评述了新型点阵材料的制备工艺、结构构型、力学及其他性能,指出了其发展趋势。

英文摘要：

Hypersonic vehicles represents future trends of military equipments and play an important role in future war. Light materials and structures are one of the most key. techniques in design and manufacture of hypersonic vehicles. They are foundation and safeguard of hypersonic velocity, high flexibility and long distancedestroying properties for hypersonic vehicles. Hypersonic vehicle light materials, which include honeycomb sandwich structures, foamed metals and truss structures, possess light weight, high specific strength,high specific stiffness,high toughness and good energy absorption properties. They also possess energy dissipation, heat dissipation, sound absorption and electromagnetic shielding properties. They can be used not only as structural materials, but also as function materials. In short, hypersonic vehicle light materials are excellent multi - function materials. The recent progresses of research and application of light hypersonic vehicle materials in preparation, structure design, mechanical and physical characterization are summarized in this paper. A comparison of mechanical and physical properties of three kinds of light materials are made. Fabricated process configuration, mechanical and functional properties are emphasized and the tendency of light materials is pointed out.
