Abstract: The elastic property of 2D triaxially braided composites (2DTBC) is of interest. This work proposes to formulate the global stiffness of 2DTBC for anisotropic fibre reinforcement based on concentric cylinder model (CCM). The results of the global stiffness from CCM, Quek's model and Shokrieh's model are compared and the usage of each model is clarified. It is found that Shokrieh's model predicts less agreeable result with experiment due to the improper calculation of the local stiffness. The results of CCM and Quek's model are consistent and either one is recommended for use in practical situations.
