Abstract
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
