Aluminium space frame structures have been available to produce the body structures of lightweight automobiles. However, the aluminium alloy beams don't have enough strength under impact bending. In the case, bonding Carbon Fiber Reinforced Plastics (CFRP) adhesively on the beams is effective way to increase the impact strength and the absorbed energy. In the study, the impact strength and the absorbed energy of the hybrid beams consisting of aluminium-alloy and CFRP were investigated analytically and experimentally. In addition, the effects of changing the configurations and dimensions of CFRP on the impact properties of the beams were discussed based on the experimental results. The absorbed energy of the hybrid beams depended on both the thickness and length of the CFRP plates. Therefore, critical dimensions of CFRP must exist in terms of the impact strength of the beams. A simulation method to predict the critical dimensions using FEM was established considering non-liner stress-strain relations and strength of adhesive.
