刚玉石混凝土抗弹丸侵彻性能对比研究

Contrast research on penetration capability of corundum concrete

进行了Φ37mm弹对混凝土靶体和刚玉微粉混凝土靶体、刚玉碎石混凝土靶体、刚玉块石混凝土靶体的侵彻试验,得到了不同的侵彻破坏效果,结合试验数据利用计算公式得到不同刚玉石混凝土的抗侵彻系数。结果表明刚玉块石混凝土靶体抗侵彻性能最优越,刚玉碎石混凝土抗侵彻性能次之,刚玉微粉混凝土靶体比混凝土靶体抗侵彻性能提高不明显。

The penetration test was carried out with 37 mm diameter projectile penetrating the reinforced concrete target, micronized corundum concrete target, the crushed corundum concrete target and nubbly corundum concrete target. Different penetration destroying effects were observed. Penetration coefficient of corundum concrete was obtained by making use of the data of experiment and calculating expressions.The results indicate that the anti-penetration performance of nubbly corundum concrete target is better than the others, and crushed corundum concrete target takes second place, the anti-penetration capability of micronized corundum concrete target is about equal to that of reinforced concrete target.
