摘要

采用二级轻气炮加载装置和AUTODYN软件对含环氧树脂粘结层的陶瓷/金属复合装甲的抗弹性能展开了研究。陶瓷面板分为叠层和单层板两种形式，对应于C/E/A（Ceramic/Epoxy resin/Aluminum alloy）和C/E/C/E/A（Ceramic/Epoxy resin/ Ceramic/Epoxy resin/Aluminum alloy）复合装甲。结果表明，受应力波传播和破碎锥作用，C/E/C/E/A装甲较C/E/A装甲的陶瓷面板破碎程度更大。具有缓冲作用的粘结层，随其厚度的增加，陶瓷损伤程度逐渐减小，背板侵深也逐渐减小。对Yaziv系数的修订表明，在相同弹速和粘结层厚度条件下，相同面密度的叠层陶瓷装甲抗弹性能优于单层陶瓷装甲。但是，粘结层厚度的增加对C/E/C/E/A装甲的抗弹性能贡献不大，而对C/E/A复合装甲的影响却较大。最后，对于两种形式陶瓷复合装甲，粘结层均使得装甲内透射应力波幅值得到了有效衰减，尤其是C/E/C/E/A装甲。

Abstract

Here, the two-stage light gas gun equipment and the software AUTODYN were used to analyze the anti-penetration performance of ceramic/metal composite armor with epoxy resin adhesive layer. Ceramic plate has two forms including single layer form and laminated one corresponding to C/E/A (Ceramic/Epoxy resin/Aluminum alloy) armor and C/E/C/E/A (Ceramic/Epoxy resin/ Ceramic/Epoxy resin/Aluminum alloy) one. Results showed that under actions of stress wave and broken cone, crushing degree of ceramic plate in form of C/E/C/E/A armor is larger than that in form of C/E/A armor; with increase in thickness of adhesive layer possessing buffer effect, damage degree of ceramic and penetrated depth of metal plate gradually decrease. The Yaziv coefficient was revised here, it was shown that under conditions of the same velocity of anti-armor piercing projectile and adhesive layer thickness, anti-penetration performance of C/E/C/E/A armor is superior to that of C/E/A one, two armors have the same surface mass density; contribution of increase in adhesive layer thickness to anti-penetration performance of the former is not large, while that to anti-penetration performance of the latter is larger; for the two ceramic armors, adhesive layer makes penetrated stress wave amplitudes be attenuated effectively, especially, for C/E/C/E/A one.
