An effect of design parameters of NCF (Non-Crimp Fabric) on damage behavior under tensile loading has been described in this paper. Stitching yarn brings NCF not only the improvement of out-of plane strength but also intricate microscopic structure. Although numerical method considering these microscopic structures based on the superposition method has been proposed previously, the effects of the design parameters to damage behavior has not been investigated completely. In this paper, these effects have been investigated by both experimental and numerical methods. Glass fiber / epoxy specimens with two stitching pattern, two stitching pitch and two cutting direction, thus eight different samples, have been prepared and tested. Furthermore, the effects of the variance of resin-rich region obtained from surface observation have been investigated by numerical method.
