摘要

摘要: 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517 m/s的速度对强度为30 MPa、厚度为200 mm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7.8 g/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。

Abstract: Projectiles made of carbon fiber composite material shell and metal warhead have penetrated concrete targets at the speed of 336, 447 and 517 m/s, respectively. The angles are 0 and 30 between the perpendicular of target surface and projectile axes. The thickness of concrete target is 200 mm and its compression strength is 30 MPa. The experimental results indicate that the strength of composite material structure is strong. The composite projectile can go through the concrete target without fiber segregation and breakage. Given the same size of the projectile, the mass percent of filler is 18.5% in the composite material projectile, which is about twice of the metal (density of metal is takes as 7.8 g/cm3) projectile. Comparing to metal projectile, little density, high strength composite material projectile can lessen weight, improve charge-weight ratio of powder and enhance specific damage powder.
