Abstract
Abstract In order to explore the protective performance of ceramic-metal fibre composite target plate, a lightweight composite target plate consisting of aramid cloth, silicon carbide ceramic, TC4 titanium alloy, and ultra-high molecular weight polyethylene fibre plate was designed. The effects of adhesive type, stacking sequence and delamination on the protective performance of the target plate were researched through the ballistic impact test on the protective target plate with 7.62mm armour-piercing bullets. The effect of thickness variation of ceramic metal on the protective properties of target plate was investigated by LS-DYNA finite element software. It was found that the bonding effect of silicon carbide ceramics with TC4 was better than that of AB adhesive when the silica gel was used as the bonding adhesive. When the ceramic metal thickness dimension is certain, the ceramic delamination will weaken the protective structure performance, and the performance of the metal plate as the back support of the ceramic layer is better than that of the ceramic covered before and after the metal layer. The energy efficiency of the ceramic-metal structure is optimal when the ratio of the thickness of silicon carbide ceramic to TC4 is 4.84:1 for a certain surface density.
