Penetration resistance of ceramic/UHMWPE composite structures with porous titanium alloy sandwich layer

  • 摘要: 陶瓷/纤维复合装甲的纤维背板由于其刚度较低,无法为陶瓷面板提供足够的支撑,削弱了陶瓷面板对弹丸的侵蚀作用。为了增强复合装甲的整体结构刚度,在陶瓷/纤维复合装甲中加入了金属夹芯层材料,通过试验和数值模拟研究了夹芯复合装甲对12.7 mm穿燃弹的抗弹性能。试验结果表明,穿燃弹弹芯表现出脆性断裂的失效模式,复合材料装甲表现出多种失效模式,包括夹芯层的花瓣形扩孔,UHMWPE (ultra-high molecular weight polyethylene)层压板的分层和凸起变形。建立了三维数值模型来分析整个弹道响应的演变,通过试验结果验证了模拟的准确性。模拟结果表明,12.7 mm穿燃弹的被甲会对陶瓷造成损伤,同时陶瓷会侵蚀弹芯的尖卵形头部,使弹芯头部变钝从而削弱弹芯对UHMWPE背板的侵彻能力。残余弹体的动能大部分由UHMWPE层吸收,UHMWPE层压板的失效模式会随着层数的增加由剪切失效转变为拉伸失效占主导地位。此外,作为夹芯层的多孔TC4板能够为陶瓷面板提供支撑,提高陶瓷面板的吸能效果以及弹体的侵蚀作用,并且12 mm孔径的TC4夹芯层能够提供更大的刚度支撑,使整体复合结构的吸能效率提升10%。
