摘要: 为了研究陶瓷与芳纶层合板叠层结构在中高速弹丸侵彻作用下,陶瓷面板对芳纶层合板抗侵彻性能的影响,开展了13.5 g破片模拟弹丸以中高速冲击8 mm厚芳纶板、16 mm厚芳纶板、3 mm厚SiC陶瓷+8 mm厚芳纶板、3 mm厚Al2O3陶瓷+8 mm厚芳纶板4种靶板的抗侵彻性能试验。分析了有无前置陶瓷板,芳纶板受到冲击作用后,弹丸及芳纶板变形模式的差异、靶板单位面密度吸能的区别。研究结果表明:前置陶瓷板情况下,弹丸变形较大并伴随着质量磨蚀;前置陶瓷板降低了芳纶板的剪切破坏程度,增加了拉伸变形和层间分层范围;前置陶瓷结构相对于纯芳纶结构在弹速较高时抗侵彻能力较强。

Abstract: The influence of ceramic panel on anti-penetration performance of Kevlar composite laminates during the penetration of high-speed projectile into Kevlar composite laminates is studied. The anti-penetration performances of 8 mm Kevlar composite laminates, 16 mm Kevlar composite laminates, 3 mm SiC ceramic + 8 mm Kevlar composite laminates, and 3 mm Al2O3 ceramic + 8 mm Kevlar composite laminates under high-speed penetration with 13.5 g FSP are experimentally investigated. The Deformation modes of projectile and Kevlar laminates with and without ceramic plate and the average absorbed energy per unit area density are analyzed. The results show that the projectile occurs large deformation and is accompanied by a quality abrasion when penetrating the target with front ceramic plate. The front ceramic plate reduces the shear damage degree of Kevlar laminates, and increases the tensile deformation and inter-layer delamination. Compared with pure Kevlar composite laminates, the front ceramic structure has a stronger anti-penetration ability at higher projectile speed. Key
