Currently, the most important purpose in designing automobile is environment-friendly and safety performance aspect. However, the vehicle structure must be lightweight in order to improve fuel efficiency and reducing exhaust fumes. Therefore, the design of automobile should be inclined towards the safety aspects. but at the same time, it also consider reducing the structural weight of an automobile. In this study, CFRP side members with hat-shaped section was manufactured. The impact collapse tests performed with change of the stacking condition, such as interlaminar. The collapse mode and energy absorption capability were analyzed according to interlaminar number.
