A new concept of lightweight structure, namely amorphous-alloy-reinforced perforated armor (ARPA) consisting of the amorphous alloy coating and perforated metal substrate plate, is proposed. The ballistic performance of the ARPA is investigated numerically. The failure modes of ARPA and projectiles are identified, and the defeating mechanism of the ARPA is explored. It is shown that the amorphous alloy coating is helpful for enhancing the target’s ballistic performance by seriously eroding and fracturing the penetrators. The effects of coating thickness, initial impact velocity and impact angle are also discussed for the target’s ballistic performance. The optimal design of coating thickness may be necessary for enhancing the ballistic resistance of ARPAs.

提出了一种轻量化结构的新概念，即由非晶态合金涂层和穿孔金属基板组成的非晶态合金增强穿孔铠装（ARPA）。数值研究了ARPA的弹道性能。确定了ARPA和弹丸的失效模式，并探讨了ARPA的破坏机理。结果表明，非晶态合金涂层通过严重腐蚀和破坏穿透体，有助于增强目标的弹道性能。还讨论了涂层厚度，初始冲击速度和冲击角度对目标弹道性能的影响。涂层厚度的最佳设计对于增强ARPA的防弹性能可能是必需的。
