摘要/Abstract

摘要：

为提升芳纶织物的防穿刺效果,采用氧等离子体表面处理技术改性的芳纶1414织物与环氧树脂复合制备环氧芳纶复合体。分析了等离子体处理对织物功能改性的影响,研究了环氧树脂涂覆织物后复合体的防刺性能。结果表明:采用氧等离子体处理,在处理功率为600 W、处理18 min时,织物表面纤维刻蚀明显,含氧基团增多,润湿性提高,但织物拉伸强度有所下降;当环氧树脂涂覆在等离子体改性后的芳纶织物上,树脂中环氧基团与芳纶中含氧活性基团键合牢固,复合体黏结强度较好,拉伸强度较未经处理的芳纶织物增加了7.89%,复合体防穿刺效果较普通芳纶1414织物提升显著,且多层组合结构的防刺效果更优异。

Abstract:

In order to improve the stab resistance of aramid fabrics, oxygen plasma modified aramid 1414 fabrics were combined with epoxy resin to prepare epoxy aramid composites. The influence of plasma pretreatment on the functional modification of the fabric was investigated, and then stab resistance of the composites was further studied. The experiment results show that when the plasma treatment power is 600 W and the treatment time is 18 min, the fabric surface is etched obviously and the number of oxygen-containing groups increases, and the wettability is improved, but the fabric tensile strength decreases; when the epoxy resin is coated on the plasma-modified aramid fabric, the epoxy group in the resin is firmly bonded with the oxygen-containing active group in the aramid fiber and the bond strength of the complex is better. The tensile strength is increased by 7.89% and the tested composite stab resistance is significantly improved compared with the conventional aramid 1414 fabric, the multi-layered structure has more excellent stab resistance.

Key words: plasma treatment, modified aramid fiber, surface treatment, aramid epoxy composite, stab resistant material
