Much less has been done on failure characteristics of 3D (Three Dimensional) woven fabrics. This work is to attempt to this need. Shear behavior is key characteristic and play direct role to the performance of woven fabrics. In this study, three different 3D weave structures have been used to analyze the fabric shear rigidity. Shear analysis has been carried out in both directions using Kawabata evaluating system. Based on the results, a relationship of shear rigidity (G) and shear hysteresis are compared and analyzed in zero and 90o direction of fabric.
