Carbon fiber reinforced plastic (CFRP) laminates are used in various industrial fields because they have excellent properties in the specific strength and specific stiffness. The CFRP has a potential of weight reduction in the automotive structure which can contribute to the improvement of mileage as well as the reduction of carbon dioxide. On the other hand, the safety issue in case of collision should be also clarified when employing the CFRP as automotive structures. In this paper, hybrid beams which consisted of the Al Alloy beam and the CFRP laminate were examined by both experiments and numerical analyses as candidates to replace the conventional steel door guarder beam used inside the automotive door. The experimental relations of impact loading to the displacement for the Al guarder beams with different thicknesses, widths and types of CFRP showed good agreement with those from numerical results. These results show that the numerical method developed here is useful for estimating the impact behavior of CFRP/Al hybrid beams. Furthermore, the optimum design of hybrid beam was proposed by the developed numerical method here and its usefulness was demonstrated by the experiment.
