摘要
以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;利用Instron万能材料试验机对比测试上述编织复合材料的弯曲性能,研究轴纱、编织角、纤维体积分数等结构参数对材料弯曲性能的影响。结果表明,编织复合材料的弯曲性能随着编织角的增加而减少,随着轴纱、纤维体积分数的增大而增加;三维全五向编织复合材料的弯曲性能明显好于三维五向编织复合材料。
High strength alkali-free glass fibers were used as raw materials in the paper, and three-dimensional five-direction and full five-directional 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-directional braided com- posites were prepared by combined braided fabrics with resin matrix, which including epoxy resin E51 and firming agent 70# （tetralin phthalic anhydride）. Bending properties of above braided composites were tested by using In- stron universal testing machine, and influence of structure parameters, like axis yarns, braided angles and fiber vol- ume fraction, on compressive properties was studied too. The results show that bending properties increased with the increase of axis yarns and fiber volume fraction, and decreased with the increase of braided angles. Bending proper- ty of three-dimensional full five-directional composites were better than that of three-dimensional five-directional ones.
