Woven fabric composites with spread tow may induce better resin impregnation and mechanical properties than the conventional woven architectures. However, the mechanism of damage development in the woven fabric composites with spread tow has not been investigated completely. To investigate the effect of spread tow on the damage development, we have developed the numerical simulation procedure of the mechanical behavior based on damage mechanics. The macroscopic behaviors and microscopic damage states of woven composites with spread yarn are analyzed with multi-scale analysis of M^3 method. It is difficult to detect the strain level of the initial failure by the experiments, however, the strain of initial damage can be evaluated conveniently with the simulation. It is revealed that woven FRP with spread yam has good mechanical properties as compared with the conventional architectures.
