柔软的身体盔甲通常由高性能纱线编织的织物制成。机织物的抗冲击性主要取决于纤维类型、组织和线密度。最近，由高性能纱线制成的机织物被浸渍有剪切增稠流体（STF）以增强其抗冲击性。在这项研究中，五种不同的编织结构与不同的线密度的对位芳纶（Technora）纱线，然后用60%w/w的STF处理，以开发软装甲材料。使用动态抗冲击性测试仪评估未经处理和STF处理的Technora织物的能量吸收。在未经处理的条件下，平纹织物的抗冲击性能最高，其次是3/1缎面、2/2缎面、5缎面和2/2哑光。STF处理提高了所有组织结构和线密度的抗冲击性能，除了具有最高线密度的平纹组织。在STF处理后的冲击能量吸收增强方面的编织的上升顺序与在STF处理前的冲击能量吸收方面的编织的上升顺序完全相反。(C)2015爱思唯尔有限公司版权所有。
Soft body armors are generally made with fabrics woven from high performance yarns. Impact resistance of woven fabrics mostly depends upon fiber type, weave and thread density. Of late, woven fabrics made from high performance yarns are being impregnated with shear thickening fluids (STFs) to enhance their impact resistance. In this research, five different weave structures were prepared with varying thread densities of p-aramid (Technora) yarns, followed by treatment with 60% w/w STF to develop soft armor materials. Untreated and STF treated Technora fabrics were evaluated for energy absorption using dynamic impact resistance tester. In untreated condition, plain woven fabrics showed the highest impact resistance, followed by 3/1 twill, 2/2 twill, 5 end satin and 2/2 matt. STF treatment improved the impact resistance performance in all the weave structures and thread densities except for the plain weave with the highest thread density. The ascending order of weaves in terms of enhancement in impact energy absorption after STF treatment was exactly opposite to the ascending order of weaves in terms of impact energy absorption before STF treatment.
