摘要 为研究陶瓷材料应用到工程防护领域的抗侵彻性能,设计了5块装甲陶瓷-钢筋混凝土复合靶(FC-RC靶)和3块C40钢筋混凝土靶(RC靶),利用105 mm坦克炮开展了448~815 m/s着速下的侵彻试验,获到了弹/靶宏观破坏形态,测量了侵彻深度、弹坑面积和回收弹体质量、长度等试验参数,分析了2种靶体抗侵彻性能的内在机制。结果表明:弹体在撞击FC-RC靶板过程中产生明显的弹头磨蚀、弹体弯曲和破碎现象,而侵彻RC靶时却保持为刚体,说明陶瓷材料对弹体的毁伤作用是影响弹体侵彻效率下降的重要因素。最后,采用修正的BLZ公式计算得出FC靶板的侵彻系数为1. 112×10-7,达C40钢筋混凝土的7. 28倍,该系数直接反映出FC靶板具有优良的防护性能。 To investigate the penetration resistance of ceramic material applied to the engineering protection,5 pieces of armored ceramic-reinforced concrete(FC-RC)composite targets and 3 pieces of reinforced concrete(RC)targets are designed.Based on the 105 mm tank gun,penetration at 448~815 m/s are carried out.The macro-damage of the targets and the projectiles,the penetration depth,crater area and the mass and length of recovered projectiles are obtained.The internal mechanism of the penetration resistance of the FC-RC target and RC target are also discussed.It is indicated that significant warhead abrasion,body bending and fracture appear during the impact on the FC-RC target,but it maintains rigid for one penetrating into RC target,which shows that the damage effect of ceramic on projectiles is an important factor to decrease penetration efficiency.Finally,the penetration coefficient of the FC target calculated from the modified BLZ formula is 1.112×10-7,which is 7.28 times that of the C40 reinforced concrete.This coefficient directly reflects the excellent protection performance of the FC target.
