Protective effect of woven fabric reinforced rubber composite target against shaped charge jet

摘要: 基于DOP实验方法开展了玻璃纤维、 碳纤维、 Kevlar-49及PBO等四种织物增强橡胶复合靶板抗射流侵彻性能实验研究。在68°倾角下, 获取了射流侵彻四种不同结构的复合板在鉴证靶上的剩余穿深。分析了面板变形形态及四种纤维的破坏模式, 计算得到了空间防护系数及差分防护系数。结果表明: 面板的变形是干扰射流的一个重要因素, 面板孔壁与射流作用区域越长, 对射流干扰越明显。四种纤维铺层的破坏模式有着较大的差异, Kevlar-49及PBO织物增强橡胶复合板的防护能力远大于玻璃纤维和碳纤维橡胶复合板。Abstract: Based on depth of penetration (DOP) experiments, a series of anti-penetration experiments were conducted in Glass, Carbon, Kevlar-49 and PBO plain weave fabric reinforced rubber composite targets subjected to shaped charge jet penetration. The residual penetration depths for four types of composites plate in validating targets were obtained. Deformations of F-plate and damage characteristics of weave fabric were analyzed. The space efficiency factor and the differential efficiency factor of four types of plain weave fabric composite plate were calculated. Results show that deformations of F-plate has an important impact on the fragmentation and scattering of the jet. The longer interaction regions between jet and F-plate, the more obvious of jet were disturbed. The protection ability of Kevlar-49 and PBO plain weave fabric reinforced rubber composite targets are better than the other two types of composites targets.
