利用12.7 mm穿甲燃烧弹靶试陶瓷基的3种复合装甲板,探讨弹-靶的相互作用,研究陶瓷基复合装甲结构与陶瓷材料的抗弹性能。结果发现:当陶瓷板对弹丸的阻力与弹丸的作用力平衡时,陶瓷板可将弹丸挡在陶瓷板前;Al2O3陶瓷的抗弹能力优于(SiC+Si)陶瓷;须约束陶瓷板才能充分发挥其抗弹优势。在分析弹-靶作用的基础上,提出“陶瓷基复合装甲存在陶瓷组元的弹靶临界厚度”概念,当陶瓷厚度大于临界厚度时,陶瓷板能将弹丸挡在陶瓷板前,而陶瓷自身的损害几乎可以忽略;陶瓷材料存在弹靶临界厚度的必要条件是其动态硬度高于弹丸,临界厚度取决于材料动态特性、靶板结构和靶板各组元的结合强度。
Three kinds of composite armor plates of 12.7 mm armor-piercing bombs were used to investigate the interaction between bombs and targets. The anti-elastic properties of ceramic composite armor structures and ceramic materials were studied. The results show that when the resistance of the projectile to the projectile is balanced with that of the projectile, the projectile can block the projectile in front of the porcelain plate; the anti-elastic ability of the Al2O3 ceramic is better than that of the (SiC + Si) ceramic; Its anti-bombs advantage. Based on the analysis of the projectile-target effect, the concept of “the critical thickness of the projectile target in the presence of the ceramic component in the ceramic-based composite armor” is proposed. When the thickness of the ceramic is greater than the critical thickness, the projectile can block the projectile in front of the ceramic plate, The damage itself is almost negligible; the necessary condition for the critical thickness of the target to exist in the ceramic material is that its dynamic hardness is higher than that of the projectile. The critical thickness depends on the dynamic characteristics of the material, the bonding strength of the target structure and the target components.
