Abstract: According to the structure characteristics and fiber layout characteristics of the satin woven composite T-joint manufacturing by resin transfer moulding (RTM), and based on the ANSYS finite element numerical analysis platform, geometric model and finite element model which conforms to the actual structure was set up. Based on the basic idea of progressive failure strength prediction method, the numerical analysis of a modified form of Hashin failure criteria was implemented using parametric design language (APDL) of the finite element analysis software ANSYS to develop the corresponding program. A progressive failure analysis model of 2D woven composites T-joints under bending load has been developed, which using an appropriate to evaluate ultimate failure. The method can efficiently simulate mechanical response and the initiation and propagation of damage of woven composite T-joints in the process from initial loading to ultimate failure, and predict the structural static strength.
