摘要: 大口径反装甲杀伤武器在战场上发挥着越来越重要的作用,对装甲材料和结构设计提出了更高要求。为探究陶瓷复合装甲在14.5 mm穿燃弹侵彻作用下的抗弹机理与抗弹性能,设计一种铺层顺序为陶瓷/纤维/金属/柔性芯材/金属的复合装甲结构,采用试验研究方法分析厚度匹配、底板材料和柔性芯材3个因素对其抗弹性能的影响。结果表明:陶瓷面板厚度对抗弹性能影响显著,抗14.5 mm穿燃弹打击时,陶瓷面板厚度为1.38倍弹芯直径,抗弹性能较优;面密度相近、陶瓷厚度一定时,复合背板的厚度配置在一定程度上的变化对抗弹性能影响甚微;面密度相近、底板选用装甲铝时,厚度较大,抗侵彻性能更好;柔性芯材的设置既可以降低损伤面积,又可以发挥偏转功能,改变子弹侵彻底板的入射角,从而提高复合装甲的防护能力。

Abstract: Large-caliber anti-armor weapons are playing an increasingly important role in the battlefield,and higher requirements are put forward for the armor materials and structure design. In order to explore the bulllet-proof mechanisms and performance of ceramic composite armor penetrated by 14.5 mm armor-piercing projectile,an armor structure with ceramic/fiber/metal/flexible material/metal layup configuration was designed,and the influences of thickness matching,bottom plate material and flexible material on the ballistic performance were discussed through experiments.The results show that the thickness of ceramic plate has an influence on the bullet-proof performance significantly,and when the thickness of ceramic plate is 1.38 times of the core diameter,the targets have excellent bullet-proof performance. For the similar surface density and the constant ceramic thickness,the dimension matching of the composite rear plates has little influence on the bullet-proof performance when changing in a certain range.For the similar surface density,the thickness of the bottom plate should be larger when the armored aluminum is selected,and the anti-penetration performance is better. The flexible material can not only decrease the damage area,but also make the projectile yawed and change the incidence angle of projectile,thus improving the protective performance of the composite armor.
