摘　　要：采用Kevlar纤维作为原料,改变并织丙纶参数,试制14种平纹织物,以剪切增稠液体(STF)修饰织物,按照一定的复合工艺制备STF-Kevlar织物复合材料;采用万能材料试验机对织物进行交织阻力测试,借助气控高速发射装置测试复合材料的防弹性能,探讨不同的丙纶参数对复合材料性能的影响。结果表明:随着Kevlar织物中丙纶线密度的增加,加强纱线间的结合,织物交织阻力增大,复合材料的防弹性能变优;织物交织阻力与并织丙纶根数呈线性关系,纱线结合度高的区域扩大,复合材料防弹性能加强;织物中丙纶分布较密,复合材料在单位面积上吸收的能量较多。This paper used Kevlar as raw materials and prepared 14 plain weave fabrics through changing PP fiber parameters. STF-Kevlar composites were prepared according to certain compound technology. Besides, universal material testing machine was used to carry out interweaving resistance test for the fabrics. Bulletproof property of composites was tested with the help of the pneumatic high-speed launcher. Effects of different PP fiber parameters on composite property were discussed. The results show that as the linear density of Kevlar fabrics rises and the combination between yarns is enhanced, interweaving resistance of fabrics increases and bulletproof properties of composites become optimal; interweaving resistance of fabrics presents a linear relation with the number of PP fibers; the zone with high yarn combination degree expands; bulletproof property of composites reinforces; PP fiber is distributed densely, and more energy is absorbed by the composites on unit area.
