トポロジー最適化による繊維強化複合材の振動特性制御

抄録

Recently, in the aerospace and automotive industries, there has been a growing interest in fiber-reinforced composites, such as CFRP (Carbon Fiber Reinforced Plastic), due to their outstanding specific strength. However, such materials have anisotropic properties that their strength depend on the orientation of fibers. Therefore, handling this anisotropy into topology optimization can bring new possibilities to the use of fibrous materials. In the present work, we propose a topology optimization method that maximizes the dynamic stability of fiber-reinforced composite structures by simultaneously optimizing the density distribution and the fiber orientation.
