摘要： 蜂窝结构具有良好的力学性能，属于一种穿孔板，具有较大的抗弹发展潜力。基于蜂窝背板，设计了一种考虑层间特性的钢/碳纤维复合材料/陶瓷/穿孔蜂窝铝层合靶，并采用有限元软件对不同攻角的弹丸侵彻特性进行了数值模拟。结果表明，攻角对靶板抗弹性能的影响非常大。随着攻角的减小，层合靶的变形增大，陶瓷层形成“陶瓷锥”导致的破坏区域增大。对于钢板和碳纤维板，弹孔的直径基本没有变化，但长度增大。对于蜂窝铝穿孔背板，斜侵彻时变形更大，对弹丸的干扰效果更好。垂直侵彻时弹丸的剩余速度最大，60°攻角侵彻时弹丸的剩余速度最小，降低了约350 m·s-1。

Abstract: Honeycomb structure has a great mechanical properties and belongs to a perforated plate, which has a good potential for anti-projectile. Based on honeycomb backplane, a laminated target of steel/carbon fiber composite/ceramic/perforated honeycomb aluminum was designed. The inter-layer characteristics were considered, and the penetration characteristics of projectile with different attack angles were numerically simulated by finite element software. The results showed that the attack angle had a great influence on the anti-projectile of the target plate. The deformation of the laminated target increased with the decrease of the angle of attack, and the failure area caused by the formation of "ceramic cone" in the ceramic layer increased. For steel plate and carbon fiber composite plate, the diameter of the projectile hole was basically unchanged, but the length increased. For honeycomb aluminum perforated back plate, the deformation was greater when oblique penetration, and the interference effect on projectile was better. During vertical penetration, the residual velocity of the projectile was the largest, and the residual velocity of the projectile was the smallest when the attack angle was 60°, which decreased about 350 m·s-1.
Key words: honeycomb perforated plate; laminated target; carbon fiber composite; anti-projectile penetration
