CFRP (Carbon Fiber Reinforced Plastics) of the advanced composite materials as structure materials for vehicles has a widely application in lightweight structural materials of air planes, ships and automobiles because of high strength and stiffness. the In this study, CFRP double hat-shaped section members was manufactured. The static collapse tests performed with change of the stacking condition, such as interface numbers. The collapse mode and energy absorption capability were analyzed.
