Three-dimensional multidirectional braided composites with excellent mechanical properties are expected to be widely used in the aerospace field as the main load-bearing structure. The finite element analysis (FEA) method is the most economical and effective analytical method for the study of macro-micromechanical properties of 3D multidirectional braided composites. The research progress of mesomechanical finite element method is reviewed from the aspects of meso-structure model, the prediction of stiffness and strength properties and interface performance analysis. The research status of macroscopic finite element method is introduced from the analysis of bearing capacity and impact performance of the joint structure. The main problems existing in the current research and prospects for the follow-up research are provided, which provide valuable references for the researchers to understand the research status and development trend in this field.
