Abstract:

利用碳纤维复合材料壳体和金属弹头组成的复合弹体，对混凝土靶进行了高速侵彻实验，弹体分别以336、447和517m/s的速度对强度为30MPa、厚度为200mm的混凝土靶进行正侵彻和30°斜侵彻。实验结果表明：碳纤维复合材料壳体具有较高的强度，在高速侵彻靶体的过程中弹体结构能够保持完整，复合材料壳体没有纤维分层和断裂产生。相对于同样结构尺寸的金属弹体（将复合材料壳体替换为密度7.8g/cm3的金属材料），复合材料弹填充物的质量分数（18.5%）约为金属弹体的两倍，因此采用轻质高强复合材料替代高密度金属弹身，不仅可以提高弹体装填比、增加比毁伤威力，而且还具有较高的侵彻能力。
