Experimental Study of Ballistic Performance for Boron Carbide Ceramic Composite Targets

  • 摘要: 为研究碳化硼陶瓷的抗侵彻性能,开展了$ \varnothing$12.7 mm钢球侵彻碳化硼陶瓷及复合靶板、12.7 mm长杆弹侵彻超高分子量聚乙烯纤维(UHMWPE)约束碳化硼陶瓷复合靶板实验,讨论了碳化硼陶瓷的破坏模式,研究了约束方式对碳化硼陶瓷抗侵彻性能的影响。结果表明:在钛合金/UHMWPE背板约束作用下,弹丸与陶瓷的相互作用时间更长,产生更细的陶瓷粉末,大尺寸碎片含量减少,吸收的能量更多,陶瓷的抗侵彻性能进一步提高;背板在弹体和陶瓷锥的共同冲击下,造成钛合金的花瓣形卷边破坏,UHMWPE层合板伴随着较大范围的层间分层,形成“X”形隆起现象;采用纤维约束陶瓷,使碳化硼陶瓷板在子弹侵彻时能够保持完整,增强了对弹体的磨蚀作用,提高了抗弹性能,具有一定的抗多次打击能力。通过分析碳化硼陶瓷复合装甲的抗侵彻机理,为今后复合装甲的优化设计提供了参考依据。
