约束及增韧对氧化铝陶瓷抗射流侵彻性能的影响

基于DOP实验方法开展了2种约束氧化铝陶瓷抗射流侵彻性能系列实验研究，分别获取了AD95陶瓷及10%氧化锆增韧陶瓷抗射流侵彻过程的侵彻深度-时间（P-t）曲线及他们在验证靶上的剩余穿深，并与45钢的抗侵彻数据进行了对比。结果表明:2种陶瓷抗射流侵彻的防护因数均大于1；约束陶瓷抗射流侵彻能力得到了较大提高；增韧陶瓷抗射流侵彻能力优于AD95陶瓷。基于实验结果分析了约束陶瓷抗射流侵彻的机理，提出约束边界反射产生的回爆对射流稳定性的干扰是约束陶瓷抗射流侵彻能力提高的主要原因。

Constraining and toughening effects on anti-penetration properties of alumina ceramic targets to shaped charge jets

Based on depth of penetration experiments,anti-penetration experiments were conducted in constrained AD95 ceramic targets and 10%-zirconia-toughened alumina ceramic targets subjected to shaped charge jet penetration.The depth of penetration-time curves for these two types of ceramic targets and their residual penetration depths in validating targets were obtained,and these data were compared with the corresponding experimental data for 45 steel targets.Results show that the protection coefficients of these ...
