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.

Key words： ceramic/metal composites armor adhesive layer ballistic effectiveness stress wave
