Abstract In order to improve the anti-penetration capability of foam aluminum, polyurea-coated foam aluminum composites were prepared by coating polyurea on the end faces of foam aluminum specimens with three relative densities. The effect of polyurea coating methods on the quasi-static and dynamic compressive mechanical behavior and energy-absorption characteristics of the composites was studied, and the deformation characteristics of polyurea-coated foam aluminum was discussed. The results show that the linear elastic section and the initial yield plateau section of the stress-strain curves of polyurea-coated foam aluminum are less sensitive to strain rate, and the densification section has significant strain rate sensitivity. Under dynamic loading, the polyurea coating on the end face of the foam aluminum specimen is helpful to alleviate the sawtooth oscillation in the yield plateau section of the stress-strain curves, and can improve the ideal energy-absorption efficiency corresponding to its densification strain, especially the improvement effect of ideal energy absorption efficiency of foam aluminum specimen coated with polyurea on the back pressure surface is the most obvious. Under quasi-static loading, the foam aluminum specimen coated with polyurea on the back pressure surface is still cylindrical after loading, and the deformation is relatively uniform. Under dynamic loading, the polyurea coating can effectively prevent the damage caused by the splashing of foam aluminum fragments under impact load. This study can provide a theoretical reference for the application of polyurea-coated foam aluminum composite plate in the military shelter structure.
