This research is to investigate the impact destruction of bulletproof ceramic compound materials. The bullet proof ceramic plates and the aromatic polyamide fabric as the main material to determine the different bullet proof effects between the aromatic polyamide fabrics with ceramic plates and without ceramic plates. We utilize the ANSYS 10.0 system to build the model and LS-DYNA 3D system to simulate and analyze the impact energy, and also to determine the optimal thickness of ceramic plates and the layers of aromatic polyamide fabrics. After running the simulated system, we can know the degree and the hollowness of aromatic polyamide fabrics. From the results, when ceramic plates are above 6nim, they are able to disperse the impact energy of bullet proof effectively and the bullet destroyed degree of ceramic plied with aromatic polyamide fabrics is better than single aromatic polyamide fabric, the highest value can reach 87%, and the aromatic polyamide fabrics hollowed degree can reach 0.1cm to protect bullet effectively.
