Multi-layered laminate made of ceramic/composite have been developed to prevent penetration by high velocity impact. In this study, three-layered plates consisted of 1) cover layer (glass fiber reinforced polymer), 2) Al₂O₃ ceramic plate, and 3) backing plate (glass fiber reinforced polymer) were modeled to analyze their penetration resistance to high velocity impact. As the FEA tool, commercial LS-DYNA3D was used. The analysis results were compared with experimental data of the three-layered ceramic/composite laminates tested using armor piercing projectile. The experimental data agreed well with the FEA results, and effective ballistic protection by the armor was obtained.
