The crashworthiness of Carbon Fibre Reinforced Plastic (CFRP) crash box structure subjected to quasi-static axial loading was investigated by finite element method. Glass Fibre Reinforce Plastic (GFRP), ST37 mild steel and Aluminum 6061-T6 were analyzed for comparison. In this study, the influence of materials and cross-sectional shape, on Specific Energy Absorption (SEA) and deformation pattern were examined. Finite Element Analysis (FEA) by using ANSYS LS-DYNA software used to simulate the quasi-static axial crush. It was found that CFRP material has the highest Specific Energy Absorption (SEA) compared to metal material due to its strength and lightweight. In addition, the energy absorption on the hexagonal cross-sectional shape has the highest SEA value compared to rectangular and circular shape due to its stiffness.
