Abstract: The research status of mechanical properties of three-dimensional braided composites is reviewed. The research methods can be summarized as follows: the study on the micro structures of fiber distribution, internal structure geometry and interfacial interaction, finite element analysis software to predict its mechanical properties and experimental study on mechanical properties. The study of the microscopic structure is mainly about the establishment of the single cell geometry model and the relationship between the braiding process and the cell structure model. The finite element method is mainly focused on the mechanical analysis and the stiffness strength performance prediction of the meso-structure model by finite element software and the equivalent elastic performance parameters of the material are obtained. The experimental study is to study the tensile properties, flexural properties and fatigue properties of the material. The effects of braided process parameters and temperature on the mechanical properties were analyzed. Finally, the problems existing in the current research and future development trends are prospected.
