本工作开发了一种剪切增稠流体增强织物，并研究了剪切增稠流体种类对织物抗刀刺和穿刺性能的影响。剪切增稠流体的流变性能是可调的，通过改变分散颗粒（二氧化硅，聚甲基丙烯酸甲酯和聚苯乙烯-丙烯酸乙酯）和介质（乙二醇，聚乙二醇200和聚乙二醇600）。剪切增稠流体增强织物的力学性能分别通过刮刀和钉落塔测试进行评价。粒子的硬度是影响抗刀刺性能的主要因素，而纱线间摩擦力是提高抗穿刺性能的关键因素。与纯织物相比，剪切增稠流体织物的抗刀刺和穿刺性能显著增强，这可以通过纱线拉拔测试和光学显微镜图像研究的结果来证明。系统地讨论了其增强效果，并分析了其增强机理。由于抗刀刺性和抗穿刺性的影响因素不同，分散颗粒和介质对剪切增稠流体织物的增强效果也应该不同。
This work developed a shear thickening fluid enhanced fabrics and the influence of the shear thickening fluid types on the knife stab and puncture resistance performance were investigated. The rheological properties of the shear thickening fluids were tunable by varying both the dispersing particles (silica, polymethylmethacrylate and polystyrene-ethylacrylate) and the mediums (ethylene glycol, polyethylene glycol 200 and polyethylene glycol 600). The mechanical properties of the shear thickening fluid reinforced fabrics were evaluated by the knife and spike drop tower testing, respectively. The hardness of the particles was the dominant factor for the knife stab resistance, while the inter-yarn friction played as the critical role for improving the puncture resistance. In comparison to neat fabric, the knife stab and puncture resistance of the shear thickening fluid-fabrics exhibited significant enhancement, which can be proven by the results of yarn pull-out testing and optical microscope images investigation. The enhancing effect was systematically discussed and the improving mechanism was analyzed. Because the influencing factors for the knife stab resistance and puncture resistance were different, the enhancing effect of the dispersing particles and the mediums for the shear thickening fluid-fabrics should be also different.
