Mechanical properties of fiber reinforced composites are depended on the micro and meso structures however it is difficult to predict those. In this study, we have proposed an evaluation method by which mechanical property of fiber bundle can be obtained with micro structure model under periodic boundary conditions. The strength in several directions can be evaluated by the damage development analysis. The macroscopic mechanical properties can be also obtained with meso structure model by the same method. In case of textile composites, it is also difficult even to make a finite element mesh, because we have to fill the space between fiber bundles with the resin meshes. To solve this problem, a new modeling method in which fiber bundle and resin meshes can be modeled individually, has been proposed.
