To improve the design of lightweight, high-performance bulletproof armors, three columnar ceramic/fiber laminate composite armors were designed and prepared, their ballistic behavior against 7.62 mm armor-piercing bullets was investigated. Through microcomputed tomography (micro-CT) analysis target samples, B4C ceramics found to exhibit better comprehensive properties than SiC ceramics, with a 142 % improvement in protection margin. The realized by combining ultra-high-molecular-weight polyethylene (UHMWPE) aramid III could help decrease backface signature (BFS) 53 %. A numerical simulation model established smoothed particle hydrodynamics (SPH) finite element (FE) method, called SPH–FE considering strain rate effect. accurately describe damage morphology contribution terms energy dissipation. radius ceramic layer effectively constrained ceramic. maximum error 6.41 mechanism each armor penetration process explored detail. transition from shear tensile occurred layering as marker.
