Abstract Abaqus/Explicit is used to establish the low-speed impact finite element models of composite laminates and bare plates with metal layers on the surface, and the reliability of the results is verified by comparison with the existing literatures. The research results have good reference value for composite anti-elastic structures. Johnson-Cook constitutive relation are adopted to simulate the mechanical behavior of aluminum alloy and titanium alloy layer, Hashin criterion of damage is chosen in the composite material layer failure judgment, with secondary stress criterion to simulate the failure of bonding layer Cohesive unit. The results show that the protection performance of aluminum alloy laminate on the surface is better than that of titanium alloy laminate on the surface, and the anti-impact performance of titanium alloy laminate on the surface is better than that of bare laminate on the surface. The impact resistance of [§/0/90/0/90/0]_s laminated plywood is better than the impact resistance of [§/-45/90/0/45/-45]_s laminated plywood. At the stage when the bullet just broke through the laminate and the bullet completely left the laminate, the maximum kinetic energy absorption of the bullet was obtained by aluminum alloy laminate on the surface.
