摘要/Abstract

摘要： 以2400 tex无捻玻璃纤维粗纱为原料,设计并织制了两种不同结构的三维角联锁机织预制体。以环氧树脂E51及固化剂聚醚胺WHR-H023充分混合作为树脂基体,通过真空辅助成型工艺进行复合成型。对制备出的复合材料拉伸性能进行测试,探究两种结构的力学性能差异并分析其原因。结果表明:相同工艺下,含有衬经结构的预制体制备出的复合材料纤维体积分数略高于无衬经结构的复合材料;含衬经结构的复合材料在经纬向拉伸、弯曲破坏强度、拉伸弹性模量均相对较大;不含衬经结构的复合材料在经纬向均表现出更好的韧性。

Abstract: Two wovens with different organization structures were fabricated with the linear density of 2400 tex. The resin matrix was composed of epoxy resin E51 and polyether amine WHR-H023 in a mass ratio of 3∶1. The 3D curved shallow-crossing linking woven composite was then made from surface-treated reinforcement and resin matrix by VARI method. Universal Material Testing Machine was used to characterize the tensile properties of composites. The results show that, under the same compound technology, fiber volume fraction of the composites with laying-in is larger than those without laying-in. The composites with laying-in structure possess larger tensile stress and tensile model on both of warp and weft direction. The composites without laying-in structure possess larger tolerance of energy on both of warp and weft direction.

Key words: laying-in structure, angle-interlock, composites, tensile properties
