SiC和B4C防弹插板抗多发弹打击损伤特性研

使用87式5.8 mm钢芯弹分别对SiC和B₄C复合防弹插板进行实弹靶试试验, 通过对鉴证靶凹陷深度、防弹插板背凸体积和X射线数字直接成像检测系统(DR)对防弹插板弹击损伤情况进行分析, 同时结合陶瓷材料显微结构和力学性能分析对防弹插板抗多发弹打击损伤特性进行了研究。结果表明, SiC和B₄C防弹插板都能有效防御3发5.8 mm钢芯弹的连续打击, 具有较好的抗多发弹打击性能;B₄C防弹插板与SiC防弹插板受弹击后鉴证靶凹陷深度相当, 其背凸体积较SiC防弹插板降低超过35%, 陶瓷锥底面平均直径增加30%以上, 吸收了更多的弹丸冲击动能, 这与B₄C陶瓷具有较高的硬度有关。
