A kind of lightweight armor bulletproof board and preparation method thereof

Abstract

The invention discloses a light armored armor and a preparation method thereof. The armored armor is in a sandwich structure; a core plate is made of novel aluminum matrix composite of composite enhancing silicon carbide and graphene; a face plate and a back plate are made of 5083 and 7A21 high-intensity aluminum alloy; the core plate, the face plate and the back plate are glued through metallic glue; the composite of the core plate is graphene or silicon carbide enhanced aluminum matrix composite and prepared through the pressure infiltration technology; an infiltration framework is silicon carbide and graphene cold pressing block which are uniformly mixed. According to the light armored armor and the preparation method thereof, the core plate is obtained due to infiltration of aluminum alloy through the silicon carbide and graphene composite framework, the silicon carbide enhancement is used, the enhancement and toughening functions to the aluminum alloy from the graphene are fully played, the ballistic performance of the core plate is improved, and the light armored armor having a good application prospect is finally obtained.

Description

technical field [0001] The invention relates to a lightweight armor bulletproof plate and a preparation method thereof, belonging to the field of lightweight armor protection materials. Background technique [0002] Aluminum matrix composites have high specific strength and specific stiffness, good high temperature performance and wear resistance, and low thermal expansion coefficient. At present, the reinforcements of aluminum matrix composites are mainly divided into particle reinforcements and fiber reinforcements. The fiber reinforcement not only improves the strength of the aluminum matrix, but also improves its plasticity. Carbon nanotubes are an important aluminum-based fiber reinforcement, but their production costs are high, and the potential of using carbon nanotubes to further enhance the properties of aluminum alloys is decreasing. [0003] Graphene is a new type of two-dimensional nanomaterial, its strength is as high as 1.01TPa, 100 times that of structural s...
