Axial compression and bending characteristics of CFRP hat shaped member according to orientation angle

The strength members, such as front-end side members, are subjected to axial compressive and bending load during collision. Therefore, it is important to consider energy absorption by the axial compression and the bending for design of effective strength members. And at the same time, it also should consider reducing weight of the members. In this study, CFRP (Carbon Fiber Reinforced Plastics) side members with single-hat-section shape were manufactured. The axial compression and the bending tests were performed for the members using universal testing machine, and the axial compression and the bending characteristics were analyzed. Stacking condition related to the energy absorption of composite materials is being considered as an issue for the structural efficiency. So the energy absorption of the member under the axial compressive load and the bending load were experimentally investigated.
