Abstract In this study, a new damage mode for the explosive reactive armour (ERA) of a shaped charge jet was proposed. The response characteristics of polytetrafluoroethylene (PTFE) and polyamide (PA) polymer jet impact on the ERA were analysed. The expansion degree and the diameter of the PTFE jet are larger than those of the PA jet, but the compactness of the PTFE jet head is lower than that of the PA jet, resulting in different impact pressures of the different polymer expansive jets on the target. The PTFE jet achieved the penetration without initiation of the ERA at different standoffs, while the PA jet directly detonated the sandwich charge when impacting the ERA vertically and failed to penetrate the front plate when impacting the ERA at 68°. With the increase of standoff, the reaction degree of the PTFE jet to the ERA decreased gradually, and the aperture of the front plate did not change. Graphical abstract In this article, the application of polymer in the weapon of shaped charge station is studied, and a new damage mode based on the properties of polymer material is proposed.

聚合物膨胀射流冲击爆炸反应装甲的反应特性

摘要 在这项研究中，提出了一种新的聚能射流爆炸反应装甲（ERA）损伤模式。分析了聚四氟乙烯（PTFE）和聚酰胺（PA）聚合物射流对ERA的响应特性。PTFE射流的膨胀度和直径均大于PA射流，但PTFE射流头的致密性低于PA射流，导致不同聚合物膨胀射流对目标的冲击压力不同. 聚四氟乙烯射流在不同距离下实现了穿透而不引发自爆，而 PA 射流在垂直撞击自爆时直接引爆了夹层装药，而在 68° 撞击自爆时未能穿透前板。随着间距的增加，PTFE射流对ERA的反应程度逐渐降低，并且前板的孔径没有变化。图文摘要 本文研究了聚合物在聚能装药站武器中的应用，提出了一种基于聚合物材料特性的新型损伤模式。
