【摘要】 本工作研究了由碳化硼（B₄C）/碳纤维（CF）/超高分子量聚乙烯纤维（UHMWPE）组成的复合装甲对抗7.62 mm穿甲燃烧弹的抗侵彻性能。通过实验和数值模拟,系统地研究了陶瓷复合装甲各层对弹丸的作用机理。首先将模拟与实验结果进行比较,验证了模拟方法的可靠性。在此基础上,开展了陶瓷复合装甲的陶瓷面板的材料/厚度数值模拟研究,分别采用氧化铝（Al₂O₃）、碳化硅（SiC）、碳化硼（B₄C）作为陶瓷面板,研究了不同厚度陶瓷板的吸能效率,结果表明,以B₄C陶瓷作为面板,当其厚度为10 mm时所得复合装甲的防弹性能最佳。更多还原

【Abstract】 In this paper, the anti-penetration performance of boron carbide（B₄C）/carbon fiber（CF）/ultra-high molecular weight polyethylene（UHMWPE） composite armor against 7.62 mm armor piercing incendiary projectile was studied. Through experiment and numerical simulation, the action mechanism of each layer of ceramic composite armor on projectile was studied systematically. The reliability of the simulation method is veri-fied by comparing the test results with the simulation results. On this basis, the numerical simulation of material/thickness of ceramic composite armor was carried out. Alumina（Al₂O₃）, silicon carbide（SiC） and boron carbide（B₄C） were used as panels. The energy absorption efficiency of ceramic plates with different thickness was studied. It was found that the optimal bullet-proof property was obtained when the thickness of B₄C ceramic was 10 mm.更多还原
