| 摘 要： | 利用自制落锤式冲击试验装置,该文研究了剪切增稠流体(STF)浸渍Kevlar复合材料防刺性能的瞬态受力响应过程和刺穿深度,以及STF-Kevlar复合材料的吸能机理。实验结果表明,经浸渍的Kevlar织物防刺穿力峰值提高到约400 N,复合材料的第一层受力响应时间缩短到3.5 ms,而刺穿深度降低较小。其中以120 nm SiO2配制的中间浓度的分散体系浸渍后,复合材料的防刺效果最好,防刺穿力提高至约2.7倍,刺穿深度降低了10%左右。

| Abstract: | The transient received-force response and the penetration depth of the Kevlar composites impregnated with shear thickening fluid(STF) are studied by a self-made drop-hammer tester.The energy-absorbing mechanism of the STF-Kevlar composites during penetration is analyzed.The experimental results show that the peak value of the stab resistance and penetration force of the impregnated Kevlar fabrics rises to about 400 N and the first level stress response time decreases to 3.5 ms while the penetration depth re... |
