摘要
通过压力浸渗方法制备体积分数55%B4C/7075Al复合材料,并测试其对7.62 mm穿甲燃烧弹的抗弹性能。结果表明:复合材料具有优异的抗弹性能,相比于603装甲钢,防护系数可达4.13,厚度系数可达1.37。利用SEM观察55%B4C/7075Al复合材料不同侵彻位置的微观损伤,并利用LS-DYNA对子弹侵彻靶板过程进行有限元分析模拟,重点研究靶板不同位置的应力分布,阐明了B4C/Al复合材料在弹体侵彻过程中不同位置的宏微观损伤机制。
The 55% B4 C/7075 Al composite was prepared by pressure infiltration method and its ballistic resistance to 7.62 mm armor-piercing projectile was tested. The results show that the composite has excellent ballistic property compared with 603 armored steel. The protection factor can reach 4.13 and the thickness coefficient can reach 1.37. The SEM was used to observe the microscopic damage of 55% B4 C/7075 Al composites. The finite element analysis of the penetration process into the target was carried out by LS-DYNA,and the stress distributions at different positions of the target were studied. The macroscopic and microscopic damage mechanisms of B4 C/Al composites at different locations during the penetration were clarified.
