舰船舷侧复合装甲结构抗动能穿甲模拟实验

以均质钢板前置复合材料板模拟舰船舷侧复合装甲结构,结合低速弹道冲击实验,分析了结构的破坏模式和吸能机理,比较了复合材料板与均质钢板的抗弹性能。在此基础上,根据靶板破坏模式,得到了球头弹穿透组合靶板的剩余速度预测公式,并与实验结果进行了比较。结果表明,复合材料板的面密度吸能远大于均质钢板的;组合靶板中前置复合装甲板的破坏模式主要为纤维拉伸断裂,而钢质背板则由于前置复合装甲板的影响,破坏模式主要为花瓣开裂破坏;将剩余速度理论预测值与实验数据进行比较,两者吻合较好。

Experimental study on composite armor structure of warship topside against kinetic armor-piercing

Low velocity ballistic impact experiments were carried out for composite armor system,which was combined with composite laminates at the front and homogeneous steel plates at the back.Failure modes and energy absorbing mechanism were analysed.Ballistic-resistance was compared between the composite laminates and homogeneous steel plates.Based on the experiments,an equation was obtained to predict the residual velocity for the perforation of combined targets according to failure modes.Results show that the un...
