【Abstract】 The mechanical properties of 3-D braided carbon/epoxy composites was studied. The results demonstrate that the mechanical properties can be significantly affected by the braided parameters. With the decreasing of braiding angles, the elastic module E and ultimate tensile strength σp inscrease obviously. On the basic of experiment results, fracture mechanism was analyzed.更多还原
