摘　　要：以高强无碱玻璃纤维为原料,采用四步法1×1编织工艺在全自动模块组合式编织平台上制备三维五向及全五向编织物,以E51环氧树脂、70#固化剂(四氢邻苯二甲酸酐)为树脂基体,与编织物复合制备三维五向及全五向编织复合材料.通过测试上述编织复合材料的拉伸性能,研究轴纱、编织角、纤维体积分数等结构参数对材料拉伸性能的影响.结果表明,编织复合材料的拉伸性能随着轴纱、纤维体积分数的增大而上升,随着编织角的增大而下降;三维全五向编织复合材料的拉伸性能明显优于三维五向编织复合材料.High strength alkali-free glass fibers were used as raw materials, three-dimensional five- direction and full five-direction braided fabrics were both prepared on full-automatic modular braided machine by using braided craft of four-step rule 1 × 1. Three-dimensional five-direction and full five- direction braided composites were prepared by combined braided fabrics with resin matrix, which including epoxy resin E51 and firming agent 70 # （tetralin phthalic anhydride）. Tensile properties of above braided composites were tested, and influence of structure parameters on tensile properties was studied, including axis yarns, braided angles and fiber volume fraction. The results showed that tensile properties increased with the increase of axis yarns and fiber volume fraction, and decreased with the increase of braided angles. Tensile property of three-dimensional full five-direction composites was better than that of three-dimensional five-direction ones.
