| 摘 要： | 为比较特氟龙和尼龙两种非金属射流冲击反应装甲穿而不爆的优越性，利用数值仿真和试验研究相结合的方法对两种材料的射流冲击反应装甲进行了研究分析.研究结果表明：非金属射流引起夹层炸药的起爆的因子主要来自于侵彻中的动压力以及面板、背板的对冲击波的反射加剧.对于本研究药型罩材料的选择，并非材料密度越低越适合作为前级聚能装药药型罩材料，还要兼顾射流的侵彻开孔能力，相比之下特氟龙表现出了更好的优越性.

| Abstract: | To compare the superiority of nylon jet and teflon jet penetrating without initiating the explosive reactive armor, numerical and experimental study have been carried out. The results showed that it was the dynamic pressure that initiates the sandwich explosive during the penetrating process. The reflection of stress wave between front panel and rear panel aggravates the reaction of sandwich explosive. In addition to the low density, the penetration performance should also be taken into account to choose an appropriate material for liner. Teflon, by contrast, has shown better advantages. |
