The application discloses an armor plate and a preparation method and application thereof. The armor plate is composed of ceramic, high-strength magnesium alloy, an ultra-high molecular weight polyethylene fiber laminated plate, a crack-arresting layer and an adhesive. The magnesium alloy plate with high damping performance is used as the intermediate transition layer of the armor plate, and plays a rigid supporting role on the ceramic. Meanwhile, the laser remelting is carried out on the bullet-approaching surface and the back surface of the alloy plate respectively, and the micro-texture with different appearances is generated. The micro-texture changes the normal contact stiffness of the alloy plate, and thus changes the stress reaction speed and relaxation characteristics of the alloy plate at the moment of bullet impact. In addition, the existence of the micro-texture also improves the interface bonding strength. Finally, the overall bulletproof capability of the armor plate is improved.
