通过一系列的实验比较和分析研究 ,客观地评价了三维编织工艺参数对复合材料拉伸性能的影响。实验结果表明 :三维编织复合材料具有良好的力学性能 ,纤维表面编织角、纤维体积分数和纤维束细度对复合材料拉伸性能有较大的影响 Through a series of experimental comparisons and analyzes, the impact of three-dimensional weaving process parameters on the tensile properties of composites was objectively evaluated. The experimental results show that the three-dimensional braided composites have good mechanical properties, and the braiding angle, fiber volume fraction and fiber bundle fineness have a great influence on the tensile properties of the composites
