摘要：

Based on experimental investigation and finite element analysis (FEA) of braided composites, an empirical failure criterion of strength was proposed to meet the need of engineering application. A strength prediction method of 3D braided composites was introduced by using the model of modulus prediction and the results of FEA. Numerical calculation results indicate that the predicted strength of 3D braided composites agrees quite well with the results of tensile experiment.
