摘要/Abstract

摘要： 本文以64tex亚麻纤维、33tex丙纶(PP)纤维为原料,在花式捻线机上形成PP包覆亚麻的包缠纱;分别以上述包缠纱作为经纬纱,在SU111型全自动剑杆织样机上制织三种典型2.5维机织物(浅交弯联、浅交直联、深角联),并在Carver热压设备上热压制成2.5维机织复合材料板材。分别选取厚度为1mm、纤维体积含量为48%的上述三种2.5维机织复合材料进行低速冲击性能研究。结果表明,浅交弯联复合材料抗低速冲击时,最大载荷最大,为575.1N,深角联最小,为301.74N;浅交弯联复合材料受低速冲击载荷时,吸收能量最多,达0.816J,深角联吸收能量最小,为0.771J。

Abstract: In this work, PP (64tex) filaments were wrapped in the flax (33tex) surface to form PP/flax covered yarn. The covered yarns were used to weave three typical 2.5D woven fabrics(deep crossing linking, straight shallow-crossing linking and the curved one) on SU111 type automatic rapier loom. Then those woven fabrics were made into PP/ flax composites by hot pressing in the Carver hot-pressing equipment. The low-velocity impact performance of 2.5D woven composites (thickness was 1mm, fiber volume content is 48%)was texted. The results showed when the curved shallow-crossing linking composites resist to low speed impact, the biggest load(575.1N) was bigger than others, while the biggest load of deep crossing linking composites(301.74) was the smallest. When the curved shallow-crossing linking composites resisted to low speed impact, it absorbed the most energy(0.816J), while the biggest load of deep crossing linking composites(0.773) was the least.

Key words: 2.5D woven composites, low-velocity impact performance, curved shallow-crossing linking, straight shallow-crossing, deep crossing linking
