Abstract The advancement of lightweight protective armors holds critical importance for enhancing the maneuverability and combat capabilities of sex-swings helicopters.Leveraging insights from bionics, it provides a new idea for high-performance armor design.In this study, a new type of composite armor was designed by referring to the structural characteristics of hard phase-protection, soft phase-buffering of unitization armadillo shell.Through the numerical study, the anti-ballistic performance of armor with varying thickness ratios of the dense ceramic layer to the interpenetrating layer is obtained, and the influence of different structures of armor on the anti-ballistic performance is analyzed.The Input Power Wire results show that compared with the traditional laminated composite armor, the Al2O3/Al biomimetic composite armor not only improves the separation phenomenon caused by wave impedance mismatch, but also greatly improves the speed drop in resisting high-speed and penetrating bullets.

When the thickness ratio is 2:1, the armor has higher ballistic protection performance.
