低コストCFRTP開発のための炭素繊維の配置・配向の最適化

抄録

In this study, we proposed an optimization method for carbon fiber allocation and orientation to reduce the cost of CFRTP. CFRTP is effective in reducing the weight of transportation equipment. However, the high material cost of CFRTP possesses a problem for the practical application of CFRTP. Therefore, we focused on the allocation and orientation of carbon fibers that affect the material properties of CFRTP to develop low cost and high stiffness CFRTP using minimal carbon fibers. The allocation of carbon fiber is determined by topology optimization employed in the proposed optimization method. Similarly, the orientation of carbon fiber is determined by the principal stress. Thus, high stiffness CFRTP with fewer fibers can be obtained using the proposed optimization method.
