The resin material such as polycarbonates (PC) is considered as the new impact materials such as windshields of automobiles. But, the material has the weak point of rigidity. Then, it is proposed that PC resin is composed with the glass fiber. In this research, the impact penetration fracture when the impact body collides with the center of the PC Laminated Sheet is analyzed. This behavior is analyzed by using the Distinct Element Method (DEM). DEM is suitable for the analysis of the fracture behavior from the non-individual body to the break-up body. In addition to the analysis, the experiment is performed by using an actual material. The analytical result and the experiment are compared From the results, it has been understood that the effect of the outside layer is large and accumulating is not effective.
