The ballistic performance of a hybrid-cored sandwich structure was studied by using ballistic penetration test. Considering the failure modes and efficiency of absorbed energy, the anti-projectile mechanism of the hybrid-cored sandwich structure was synthetically analyzed. The experimental results indicate that anti-projectile capability is substantially enhanced in a high-amplitude extent. During the penetration of the spherical projectile, the kinetic energy of the projectile is absorbed mainly through the large plastic deformation and shearing expansion of the pyramidal lattice structure, the fracture failure of ceramics rods and hybrid epoxy, and the macroscopically bending deformation of the faces. The results can offer some helpful references for the protection design of lightweight composite armor.
