Abstract

The penetration ability of a 5.8 mm standard projectile can be improved by inserting a ZrO ceramic ball with high hardness, high temperature, and pressure resistance at its head. Thereby, a ceramic composite projectile can be formed. A depth of penetration (DOP) experiment and numerical simulation were conducted under the same condition to study the armor-piercing effectiveness of a standard projectile and ceramic composite projectile on 10 mm Rolled Homogeneous Armor (RHA) and ceramic/Kevlar composite armor, respectively. The results show that both the ceramic composite and standard projectiles penetrated the armor steel target at the same velocity (850 m/s). The perforated areas of the former (φ5 mm & φ2 mm) were 2.32 and 2.16 times larger, respectively, than those of the latter. The residual core masses of these two projectiles (φ5 mm & φ2 mm) were enhanced by 30.45% and 22.23%. Both projectiles penetrated the ceramic/Kevlar composite armor at the same velocity (750 m/s). Compared with the standard projectile, the residual core masses of the ceramic composite one (Ø5 mm & Ø2 mm) were enhanced by 12.4% and 3.6%, respectively. This paper also analyzes the penetration mechanism of the ceramic composite projectile on target plates by calculating its impact pressure. The results show that the ceramic composite projectile outperformed the standard projectile in penetration tests. The research results are instructive in promoting the application of the ZrO ceramic composite in an armor-piercing projectile design.

摘要

通过在5.8毫米标准弹丸头部插入具有高硬度、耐高温和耐高压性能的ZrO陶瓷球，可以提高其侵彻能力。由此，可以形成一种陶瓷复合弹丸。在相同条件下进行了侵彻深度（DOP）实验和数值模拟，分别研究标准弹丸和陶瓷复合弹丸对10毫米均质装甲钢（RHA）和陶瓷/凯夫拉复合装甲的穿甲效能。结果表明，陶瓷复合弹丸和标准弹丸以相同速度（850米/秒）穿透装甲钢靶。前者（直径5毫米和直径2毫米）的穿孔面积分别比后者大2.32倍和2.16倍。这两种弹丸（直径5毫米和直径2毫米）的剩余弹芯质量分别提高了30.45%和22.23%。两种弹丸以相同速度（750米/秒）穿透陶瓷/凯夫拉复合装甲。与标准弹丸相比，陶瓷复合弹丸（直径5毫米和直径2毫米）的剩余弹芯质量分别提高了12.4%和3.6%。本文还通过计算陶瓷复合弹丸的冲击压力，分析了其对靶板的侵彻机理。结果表明，在侵彻试验中，陶瓷复合弹丸的性能优于标准弹丸。研究结果对推动ZrO陶瓷复合材料在穿甲弹设计中的应用具有指导意义。
