As woven fabric composite materials have the excellent impact resistance and ductility, it is used for many industrial and aerospace fields. However, it is very difficult to evaluate the mechanical behavior because of the complicated geometrical architecture. We have proposed the evaluation system for the mechanical behaviors by FEM with the finite element mesh generation of the microstructure. In this paper, a finite element mesh generator based on the fiber bundle data obtained by WiseTex and a simulation system for the mechanical behaviors of woven composites have been described. As an example, the mechanical behavior of H Shape structure with 3D woven composites is carried out. It is revealed that the mechanical characterization of textile composites can be evaluated by the proposed system.
