Embodiment Construction

[0015] In order to better explain the present invention and facilitate understanding, the present invention will be further described below through specific implementation manners in conjunction with the accompanying drawings.

[0016] see figure 1 , the present invention provides a technical solution: a ceramic ball reinforced metal composite bulletproof armor and a preparation method thereof, which includes: ceramic balls 2 are distributed in the bulletproof metal 1 by the lost foam casting method, and the arrangement of the ceramic balls 2 The ceramic balls of each layer are tangent to each other, located in the gap formed by three ceramic balls in the second layer, and are tangent to the three ceramic balls at the same time, and the multi-layer ceramic balls are stacked repeatedly in sequence.

[0017] Further, the multi-layer ceramic pellets are fixed by using the lost foam mold, and then the metal solution is poured under negative pressure to vaporize the mold, and the l...

Abstract

The invention discloses a ceramic ball reinforced metal composite bulletproof armor and a preparation method thereof, and relates to the field of protective armors. The ceramic ball reinforced metal composite bulletproof armor and the preparation method thereof aim to solve the problems that a bulletproof ceramic / metal layered bonding structure is single in type, large in thickness and weight, poor in multi-strike resistance, prone to layered damage and the like. According to the ceramic ball reinforced metal composite bulletproof armor and the preparation method thereof, ceramic balls are evenly dispersed and cast in a metal plate according to a certain arrangement sequence and distribution structure through a lost foam casting method to form the ceramic ball reinforced metal composite bulletproof armor, and the ceramic ball reinforced metal composite bulletproof armor can be widely applied to bulletproof armors of military equipment such as vehicles, tanks and armed helicopters.

Description

technical field [0001] The patent of the invention discloses a metal composite bulletproof armor reinforced by ceramic pellets and a preparation method thereof, and relates to the field of bulletproof armor. Background technique [0002] At present, ceramic / metal composite armor is mostly a layered structure composed of bulletproof ceramic plates and bulletproof metal plates bonded by thermocompression. The composite armor of this structure has a large overall thickness and weight, and the space for structural optimization is small, which cannot meet the needs of further weight reduction of military equipment. After the structural armor is hit by a bullet, the bulletproof ceramic plate is prone to fragmentation, and the bulletproof performance decreases, which affects the armor's resistance to multiple bullets. The layered bonded structure withstands bumps and vibrations for a long time. Under the environment, delamination damage is prone to occur. Contents of the inventio...
