Woven fabrics have been applied widely to many structures. There are many requirements that need to analyze at the micro level. In order to investigate the behavior of the filaments of woven structures at the micro level, a new computational method that the mechanical behavior of composite materials can simulate in consideration of the large-scale differences is required. Therefore, we proposed FEM with mesh superposition in 3 scales, and we defined the new numerical technology as 'M-cube (Macro-Meso-Micro) method'. In addition, the method has been expanded with damage mechanics to investigate the propagations of transverse crack in fiber bundles as an initial damage mode. The numerical results will give very important information to evaluate the safety of composite structures.
