摘要

为满足屏蔽电磁波干扰的防刺服需求,利用超声波振荡法将分散相粒径为100nm的SiO₂与聚乙二醇(PEG)200配制成剪切增稠液体(STF),利用浸渍法制成STF/芳纶复合织物。在SiO₂质量分数为15%的STF中加入平均粒径为2.75m的Fe粉,制成铁粉质量分数分别为5%、10%、15%和18%的STF-Fe非牛顿流体,研究了SiO₂含量以及Fe粉固含量对复合织物防刺性能以及STF-Fe分散体系对电磁屏蔽的影响。结果表明,复合织物的防刺效果随着SiO₂、Fe含量的增加而增强。SiO₂质量分数大于15%时,复合织物的刀刺载荷明显提高。STF-Fe分散体系可以显著提高芳纶织物的刀刺性能,但效果不如STF。随着SiO₂含量的增加,STF/芳纶复合材料的防刺效果明显提高;在SiO₂质量分数为15%的条件下,随着Fe含量的增加,STF-Fe/芳纶复合织物的锥刺性能明显提高。当STF-Fe分散体系中Fe质量分数达到40%时,电磁屏蔽率可达到90%～99.9%。

Abstract

In order to make puncture-resisting armor with electromagnetic shielding property,an ultrasonic vibration method was employed to disperse 100 nm SiO₂ and PEG 200 into shear thickening liquid (STF),and then fabricated into STF/aramid composite fabric using an impregnation method.2.75m Fe was added into STF containing 15% SiO₂,STF-Fe non-Newtonian fluid with different solid contents of Fe (5%,10%,15% and 18%) was formed.The effects of SiO₂ and Fe contents on puncture resistance as well as the effect of Fe content on electromagnetic shielding were studied.Research results showed that,puncture resistance increased obviously with increasing SiO₂ and Fe contents.When the content of SiO₂ was more than 15%,the knife resistance was improved more significantly.STF-Fe can obviously increased the knife resistance,but the enhancing effect was less than the same solid content of STF.Stab resistance of STF/aramid fabric was obviously enhanced with increasing SiO₂ content.When 15% SiO₂ contained in STF-Fe,the spike resistance received an obvious increment with increasing Fe content.When Fe content reached 40%,the electromagnetic shielding efficiency attained 90%～99.9%.
