玻璃及玻璃/钨复合材料药型罩的静破甲特性研究

为研究玻璃及玻璃/钨复合材料药型罩射流与靶板间的反应及其对破甲性能的影响，对两种材料射流侵彻后的45钢靶分别进行组织和性能测试分析.结果表明:玻璃药型罩适合在较大炸高条件下使用，而玻璃/钨药型罩适合在小炸高条件下使用.侵彻过程中玻璃射流与钢靶之间不发生反应，而玻璃/钨与钢靶之间发生反应生成了Fe-W相，使得射流能量部分横向耗散.玻璃及玻璃/钨射流在侵彻钢靶的过程中均会引起弹孔表面发生马氏体相变，且随着侵彻的深入，相变区域宽度呈增加的趋势. 

Penetration Performance of Glass and Glass/Tungsten Compositeas Shaped Charge Liner Materials

In order to investigate the effect of the interaction between the jets of glass and glass/tungsten composite and 45 steel targets on the penetration performance,the microstructures and properties of the targets after penetrated by the jets were characterized. Results show that,taking the glass as a shaped charge liner material,a better penetration depth can achieve in static-exploded at larger height. While the shaped charge liner made with glass/tungsten composite is more suitable for the static-exploded at lower height. During penetrating,there is no interaction between the glass jet and the steel target,and a Fe-W compound can produce between the glass/tungsten jet and the steel target,consuming part of the jet energy for broadening the hole along transverse direction. Pearlite-martensitic transformation on the ballistic surface occurs during penetration for both glass and glass/tungsten jets,and the width of martensitic area increases with the penetration depth increasing.
