摘　　要：以碳化硅陶瓷(SiC)作为面板材料,超高分子量聚乙烯纤维增强水性聚氨酯树脂基复合材料层压板(UHMWPE/WPU)作为背板材料,通过真空袋膜压工艺制备SiC-UHMWPE/WPU复合装甲板。基于弹道冲击试验研究复合装甲板的结构参数对其抗穿甲弹侵彻性能的影响,采用X射线计算机断层扫描(X-ray computed tomography,CT)技术,研究复合装甲板在53式7.62 mm穿甲弹以弹速为(808^(+7)_(-8))m/s进行多发弹道侵彻下的损伤模式。研究结果表明:SiC-UHMWPE/WPU复合装甲板的抗多发弹道侵彻能力随着UHMWPE/WPU厚度或SiC厚度的降低而逐渐下降,10 mm厚SiC+13 mm厚UHMWPE/WPU是试验中抗53式7.62 mm穿甲弹多发弹道侵彻的最佳工程应用结构;UHMWPE/WPU面密度的减少不仅影响UHMWPE/WPU的防护效率,其还通过降低对陶瓷面板的支撑作用,间接影响陶瓷的防护效率;弹道侵彻后的复合装甲板的损伤模式包括SiC碎裂、SiC与UHMWPE/WPU的界面破坏及UHMWPE/WPU的绝热剪切破坏、拉伸变形和分层破坏。The silicon carbide ceramics(SiC) and ultra-high molecular weight polyethylene fiber reinforced waterborne polyurethane composite laminate(UHMWPE/WPU) were used to prepare SiC-UHMWPE/WPU composite armor plate by resin film infusion. Based on ballistic impact test, the influence of structural parameters of the composite armor plate on the anti-penetration performance of armor-piercing projectile was investigated. The damage mode of the post-impact SiC-UHMWPE/WPU composite armor plate, which was repeatedly impacted by type-53and 7.62 mm armor piercing projectile at a velocity of(808^(+7)_(-8))graphy(CT) technology. The results show that the anti-multiple penetration performance of SiC-UHMWPE/WPU composite armor plate decreases gradually with the reduction of UHMWPE/WPU thickness or SiC thickness. Significantly, 10 mm-thick SiC+13 mm-thick UHMWPE/WPU may be the best engineering application structure to resist the multiple ballistic penetration of type 53 and 7.62 mm armor piercing projectile in the test. The reduction of area density of UHMWPE/WPU not only affects the protection efficiency of UHMWPE/WPU, but also indirectly affects the protection efficiency of ceramics via decreasing the support effect. Moreover, the damage modes of post-impact composite armor plate include SiC fragmentation, interface failure between SiC and UHMWPE/WPU, adiabatic shear failure, tensile deformation and delamination failure of UHMWPE/WPU.
