Laminated woven fabric composites may induce better resin impregnation and mechanical properties ... more Laminated woven fabric composites may induce better resin impregnation and mechanical properties than the conventional uni-directional laminates. However, cross sections and shapes of fiber bundles change at the cross-over parts of bundles, and the effects of a change of geometry of fiber bundles on the damage development had not been investigated. Therefore, we have developed the simulation program of mechanical behaviors for woven composites based on damage mechanics. A FE mesh generator and the simulation technique of mechanical behaviors of laminated woven fabric FRP considering the changes of shape of fiber bundles and volume fractions caused by nesting have been developed. As the numerical results, the initial stiffness showed same tendency at each numerical model, however, the location of damage and the propagation is quite different due to the effect of shape and scale of fiber bundles. From these results, the mechanical behaviors of laminated woven composites can be estimated with the proposed method.
