随着航空航天科技的迅猛发展，人们对高性能工程材料的设计与制备提出了更高的要求，夹层结构因其具有良好的抗冲击性能，得到了广泛的应用。简要介绍了目前航空航天上主要应用的几种夹层结构的抗冲击性能的研究现状，分析比较几种夹层结构的抗冲击性能，为航空航天夹层结构抗冲击性能的设计和研究提供参考．
英文摘要：
With rapid development of aero- space technology, the sandwich structures with excellent performance have been widely applied. The anti-impact property of three types of sandwich structures applied in aerospace are briefly introduced. Then the arti-impact property of different sandwich structures are analyzed. The design and research of anti-impact behavior of the sand- wich structures in aerospace is provided for reference.
