SiC/UHMWPE复合装甲板抗侵彻性能的试验与数值模拟

Anti-penetration capability of SiC/UHMWPE composite armour plates through experimental and numerical simulation

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5.8mm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.
