▎ 摘　　要

NOVELTY - Graphene composite bullet-proof plate comprise a bullet-facing surface orderly provided with crack-proof layer, graphene bullet-proof ceramic layer (3), first transition layer (4), second transition layer (5) and back plate (6), between two adjacent layers by hot melt adhesive layer (2), bonding the graphene bullet-proof ceramic layer is made of aluminum oxide ballistic ceramic added with graphene powder, silicon carbide bullet-proof ceramic, boron carbide bulletproof ceramic, where the adding amount of the graphene powder is 0.5-1 % total mass of the layer. USE - Graphene composite bullet-proof plate. ADVANTAGE - The graphene composite bullet-proof plate provides stable protection ability, by optimizing bullet-proof structure design, composite bullet-proof plate total surface density is in the range of 40-45kg/m2, and prevents the impact of 3-53 type 7.62mmAPI. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a graphene composite bullet-proof plate, involving: a. preparing a first transition layer, a second transition layer and a back plate by a layer hot pressing process; b. orderly paving graphene bullet-proof ceramic layer, the first transition layer, the second transition layer, the back plate, where each layer is added with hot melt adhesive bonding to form a preform; and c. putting the preform into a vacuum bag, putting the vacuum bag into the hot pressing tank for periodically heating and vacuumizing, cooling to obtain peoduct. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a gGraphene composite bullet-proof plate. Anti-cracking layer (1) Hot melt adhesive film layer (2) Graphene bullet-proof ceramic layer (3) First transition layer (4) Second transition layer (5) Backplate (6)
