采用碳化硅(SiC)陶瓷结合超高分子聚乙烯(ultra-high molecular weight polyethylene, UHMWPE)硬-软结构, 设计出 4 种不同配比的轻型复合装甲板.研究了不同类型小口径子弹对不同配比复合装甲板的侵彻性能,同时运用 LS-DYNA 软件对侵彻过程进行了数值模拟分析,模拟结果与试验结果具有较好的一致性. 结果表明,该硬-软结构的轻型复合装甲板能有效防护 7.62 和 5.8 mm 小口径弹药的进攻, 极大地提升了防护性能.

With the hard-soft structure of silicon carbide (SiC) ceramics with ultra-high molecular weight polyethylene (UHMWPE), four light-weight composite armour plates for different ratios have been designed. Tests on the penetration capability of several different types of small-bore bullets impacting each composite armour plate have been conducted, and numerical simulation analysis through the LS-DYNA program for the penetration process has been carried out as well. The test results and the numerical simulation results are found to be in good agreement. This indicates that the light-weight composite armour plates of hard-soft structure can effectively block the penetration from 7.62 and 5.8 mm small-bore bullets and greatly improves the protection capability.
