摘　　要：为研究枪弹穿甲后效破片对有防护人员的杀伤作用效能,采用一种易碎钨合金弹芯材料的穿甲枪弹、10 mm厚均质钢板和典型聚乙烯(PE)复合材料防弹衣,进行穿甲后效试验。分析穿甲后效破片的质量分布和飞散规律,以及两种不同速度弹头穿甲后效破片对防弹衣的侵彻毁伤效果。研究结果表明:枪弹穿甲后效破片的质量分布范围较大,后效破片在距离防护钢板1. 4 m处的散布半径为21. 3 cm;枪弹穿甲形成的不规则后效破片对PE防弹衣各纤维层的破坏模式以剪切破坏为主,纤维材料在发生剪切破坏的同时,伴有纤维材料的熔融、灼烧破坏;在后效破片密集作用区,各侵彻孔间的边界相互交叉产生撕裂破坏,形成了相互连通的大破口,且大破口周围产生纤维撕裂扩展,能够加剧破坏程度。In order to explore the killing ability of the after-effect fragments of bullet,an after-effect experimental was carried out based on an armor-piercing bullet with tungsten alloy penetrator,10 mm-thick homogeneous steel plate and a typical polyethylene composite body armor. The mass distribution and dispersion law of after-effect fragments and the penetration effects of after-effect fragments penetrating into body armor at different velocities are analyzed. The results show that the mass distribution range of aftereffect fragments is larger;the dispersion radius of after-effect fragments at 1. 4 m from the protective steel plate is 21. 3 cm;the failure mode of body armor is dominated by shear failure,and at the same time,it is accompanied by the melting and burning damages. The boundary between penetration holes is torn due to the boundary intersection,and a large open gap is formed to develop tear propagation and exacerbate the damage.
