Paper Abstract

In vehicle industry, the design of vehicle should be inclined towards the safety performance aspect, at the same time; it also should have weight loss of a vehicles structural member. In this study, experimental investigations are performed for Al/CFRP Hybrid structural members. They are cured by heating to the appropriate curing temperature (130°C) by means of a heater at the vacuum bag of the autoclave. Because the CFRP is an anisotropic material whose mechanical properties, such as strength and elasticity, change with its stacking condition, special attention was given to the effects of the stacking condition on the collapse behavior evaluation of the Al/CFRP Hybrid structural members. The collapse mode and energy absorption capability of the Al/CFRP Hybrid structural members was analyzed with change of the fiber orientation. The stacking condition were selected to investigate the effect of the fiber orientation angle (±15°, ±45°, 90°, 0°/90°and 90°/0° where 0°direction coincides with axis of the member)on the energy absorption of the Al/CFRP Hybrid structural members. The collapse mode and energy absorption capability of Al/CFRP Hybrid structural members was analyzed with change of the fiber orientation of CFRP.
