Abstract: Honeycomb sandwich structure is more and more used in military vehicles and ships as a potential armor structure because of its good protection effect against bullets and various explosives. Generally, honeycomb sandwich structures will be subjected to different forms of high-speed impact such as bullets and explosives in the battlefield environment, and these impacts will cause different forms of damage to honeycomb sandwich structures. Therefore, scholars at home and abroad have conducted a lot of research on the anti-high-speed impact performance and damage mode of honeycomb sandwich structures. This paper reviews and summarizes the domestic and foreign research on two different forms of high speed impact, namely, explosion impact and ballistic impact. In terms of explosion impact, it discusses the air blast test, underwater explosion test, fluid-structure coupling effect and core form difference, and in terms of ballistic impact, it discusses the air gun test, equivalent modeling of honeycomb sandwich structure, damage form of panel and ballistic limit velocity. Finally, this paper discusses the shortcomings and improvement methods in the current high-speed impact test and simulation of honeycomb sandwich structures.

Key words: composite material, honeycomb sandwich structure, ballistic impact, explosion shock
