在相同剪切增稠行为的基础上，研究了质量分数为20%的剪切增稠液中的气相二氧化硅和质量分数为65%的剪切增稠液中的亚微米二氧化硅颗粒对浸渍剪切增稠液的织物的准静态抗刺伤性能的影响。为了更好地了解这两种不同的二氧化硅颗粒在准静态刺针过程中对织物阻力的影响机理，进行了单纱拉伸试验以获得单纱的拉伸性能，并通过纱线拔出试验考察了纱线间的界面摩擦。结果表明，经剪切增稠液处理的芳纶织物的准静态抗刺伤性能显著提高。此外，含有亚微米二氧化硅颗粒的整理织物的准静态抗刺伤性能好于含有气相二氧化硅颗粒的整理织物。对增强的可能机制进行了详细讨论。(C)爱思唯尔有限公司出版的2014年。
The effects of fumed silica in shear thickening fluids at a weight fraction of 20% and submicron silica particles in shear thickening fluids at a weight fraction of 65% on quasi-static stab resistance properties of fabrics impregnated with shear thickening fluids were investigated on a basis of a similar shear thickening behavior. For better understanding of the effects of these two different silica particles on resistance mechanism of fabric during quasi-static stab, the single yarn tensile test was carried out to obtain tensile properties of single yarn and yarn pullout test was performed to examine interface friction among yarns. The results show that aramid fabrics treated with shear thickening fluid exhibit a significant enhancement in quasi-static stab resistance. Further, quasi-static stab resistant properties of treated fabrics containing submicron silica particles are better than that of treated fabrics containing fumed silica particles. Possible mechanism responsible for the enhancement is discussed in detail. (C) 2014 Published by Elsevier Ltd.
