Woven Composite laminates consist of a pile of woven layers impregnated with resin. As it is difficult to control the position of each layer, a nesting phenomena which mean a relative position of each layers is disordered, have been appeared. It is important to clear the effect of the nesting on the damage of woven fabric composites. The nesting causes the deformation of fiber bundles and the changes of distributions of fiber volume fraction. In this paper, FE analyses based on damage mechanics have been carried out with nesting FE models. The effect of nesting on the mechanical properties has been investigated with finite element method based on damage mechanics. The numerical results show that the fiber volume fraction in bundles has the most important for the damage development of woven composites laminates.
