【摘要】 采用53式7.62 mm穿甲燃烧弹分别对高温处理后的整板Si C和B₄C防弹插板进行3次连续有效射击，分析插板凹陷深度、陶瓷面板毁伤情况及断口形貌显微结构，对防弹插板的耐损伤特性进行研究，并分析陶瓷力学性能与插板抗多发弹性能的关系；随后采用超高分子量聚乙烯薄膜材料和超高分子量聚乙烯纤维UD预浸料制备防弹插板进行靶试试验，分析了插板靶试结果、防弹机理。研究结果表明，使用超高分子量聚乙烯纤维UD预浸料的插板抗穿透性能优于薄膜材料，超高分子量聚乙烯薄膜材料在吸收冲击能量方面更有效。Si C和B₄C与超高分子量聚乙烯纤维复合防弹插板在高温条件下均能抵御住3发53式7.62 mm穿甲燃烧弹的连续打击，具有良好的抗多发弹打击性能。此外，Si C防弹插板的抗多发弹性能稳定性优于B₄C防弹插板，B₄C防弹插板抗单发弹性能优于Si C防弹插板。陶瓷的强度和硬度有利于提高陶瓷的抗弹性能，而其韧性在防弹插板的抗多发弹性能方面发挥了重要作用。更多还原

【Abstract】 The type 53 7.62 mm armor-piercing incendiary bomb was used to shoot Si C and B₄C bulletproof inserts after high temperature treatment for three consecutive times.The depression depth of the inserts,the damage of the ceramic panels and the frac‐ture morphology and microstructure were analyzed.The damage resistance characteristics of the bulletproof inserts were studied,and the relationship between the mechanical properties of the ceramics and the anti-multiple bomb performance of the inserts was analyzed.Then the target test of bulletproof insert plate prepared by ultra high molecular weight polyethylene（PE-UHMW） film material and PE-UHMW fiber UD prepreg was carried out.The test results and the mechanism of bulletproof insert plate were analyzed.The results show that the penetration resistance of the insert plate using PE-UHMW fiber UD prepreg is better than that of the thin film material,and the thin film material is more effective in absorbing the impact energy.Si C and B₄C with PE-UHMW fiber bulletproof inserts can withstand the continuous attack of three 53-type 7.62 mm armor-piercing incendiary bombs under high temperature conditions,showing good anti-multiple bomb attack performance.In addition,the anti-multiple bomb stability of Si C bulletproof insert is better than that of B₄C bulletproof insert,and the anti-single bomb property of B₄C bulletproof insert is better than that of Si C bulletproof insert.The strength and hardness of ceramics are beneficial for improving the anti-elastic properties of ceramics,and the toughness of ceramics plays an important role in the anti-multiple bomb properties of bulletproof inserts.更多还原
