Abstract
In automobiles, the CFRP has a possibility of weight of reduction in automotive structures which can contribute to improve mileage and then to reduce Carbon dioxide. On the other hand, the safety of collision should be also made clear in the case of employing the CFRP to automotive structures. In the paper, the CFRP guarder belt equipped in the automotive door is developed and examined by an experiment for replacing the conventional steel door guarder beam. The impact response behavior and the absorbed energy of the CFRP guarder belt were obtained by the tower drop weight impact test. The experimental relation of impact load to displacement for CFRP guarder belt agreed well with that of numerical result. From the results, the numerical method developed here is quite useful for estimating impact behaviors of CFRP guarder belt.
