Carbon fiber reinforced plastic (CFRP) laminates are used in various industrial fields because they have excellent properties of a specific strength and a 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 the present study, the authors developed CFRP-steel hybrid members designed and fabricated for the purpose of designing impact energy absorption members under lateral collision. Drop weight impact tests were carried out to investigate impact response behaviours and impact energy absorption characteristics of the CFRP-steel hybrid members. Also, numerical analysis using dynamic simulation solver PAM-CRASH is performed to compare the numerical results with the experimental ones. The energy absorption capability of the Type-B specimen was excellent because the impact absorption members of the automobiles were required limited deformation. In case of the impact response tendency, the numerical results agreed with the experimental ones.
