Auxetic materials have many advantages in strength and energy absorption, which have become a research focus of scholars at home and abroad. It’s of great significance to ship protection structure design that researching deeply on auxetic lattice structures. According to the unique properties of auxetic lattice structures, this paper mainly introduces the research status of the impact resistance mechanical properties of the new structure. The research status of low-speed impact, high-speed projectile impact, and explosion impact in the auxetic lattice structures is described from three aspects: theoretical, experimental and simulation studies. The research status of in-plane impact at medium and low velocities, explosive impact and projectile penetration is expounded. The effects of geometric parameters and impact velocity on deformation modes and energy absorption of structures are also analyzed. Finally, summarize the article and point out the contents in the future.
