Carbon fiber reinforced plastic (CFRP) laminates are used in the wide field, because they have excellent properties of specific strength and of specific stiffness. In automobiles, the CFRP has a possibility of weight reduction in automotive structures which can contribute to improve mileage and then to reduce Carbon dioxide. On the other hand, the safety of collision should be also made clear in the case of employing the CFRP to automotive structures. In this paper, the CFRP guarder belt equipped in the automotive door is developed and examined by an experiment and a numerical analysis for replacing the conventional steel door guarder beam. In the numerical analysis, a commercial FEM solver (ANSYS) was employed and the laminated shell element were used in the CFRP guarder belts. The contact element between the impactor and the upper surface of CFRP guarder belt and between the supporters and the inner surface of the belt was Contact element 173 with the Target element 170. The experimental relation of impact load to displacement for CFRP guarder belt agreed well with that of numerical result. From the comparison of both results, the numerical method developed here is quite useful for estimating impact behaviors of CFRP guarder belt.
