摘要

为研究陶瓷材料应用到工程防护领域的抗侵彻性能，设计了3块陶瓷-活性粉末混凝土复合靶，利用直径125mm的特制弹体对陶瓷-活性混凝土复合靶体进行DOP（Depth of Penetration）侵彻试验，得到了弹体的飞行姿态、着靶速度、破坏形态和靶体的侵彻深度、弹坑范围、破坏形态等试验参数，定性分析了陶瓷靶厚度和纤维层约束作用对复合靶体抗侵彻性能的影响。结果表明：陶瓷靶具有优良的抗侵彻性能，在低速（360~400m/s）情况下对弹体能产生一定侵蚀作用；随着陶瓷靶厚度的增加，陶瓷靶的破坏形态由冲切贯穿型转变为变形凸起型破坏，耗能能力增加，复合靶体的整体抗侵彻能力增强。采用修正的别列赞公式对陶瓷靶的侵彻系数进行了初步分析，并计算了三种厚度陶瓷靶的质量防护系数和差分防护系数。结果表明，试验所用陶瓷靶的抗侵彻能力约为普通C40混凝土的4.9倍，从而为陶瓷材料在重要防护工程的推广使用提供参考。

Abstract

To investigate the penetration resistance performance of ceramic material applied in engineering protection fields, 3 ceramic-reactive powder concrete composite targets were designed. The DOP (depth of penetration) tests were conducted using special projectiles with diameter of 125 mm to get projectiles’ flight attitude, velocity to hit targets and failure pattern as well as targets’ penetrated depth, crater range and failure pattern. Influences of ceramic target thickness and constraint action of fiber layer on penetration resistance performance of composite target were qualitatively analyzed. The results showed that the ceramic target has an excellent anti-penetration performance, the target has a certain erosion effect on projectiles at lower speeds of 360-400 m/s; With increase in ceramic target thickness, target failure mode changes from punching through type to deformed convex one, target energy dissipation capacity increases, and the whole anti-penetration ability of composite target body increases. The modified BLZ formula was used to preliminarily analyze penetration coefficient of ceramic targets, and calculate quality protection factor and differential protection one of 3 ceramic targets with different thickness. It was shown that the tested ceramic targets’ anti-penetration ability is about 4.9 times of C40 concrete targets’; the results provide a reference for popularization and application of ceramic material in important engineering protection fields.
