Embodiment 1

[0026] A type of ballistic armor that includes a metallic lattice structure, such as figure 1 As shown, it includes an upper layer 101, a middle layer 102 and a lower layer 103. The middle layer 102 is a ceramic composite material layer, and the upper layer 101 and the lower layer 103 are metal and polymer composite material layers. The metal and polymer composite material layer is a polymer material. A composite material layer formed by covering a single-layer or multi-layer metal lattice structure. like figure 2 As shown, the metal lattice structure is a flat and regular continuous structure formed by extending and arranging a plurality of cells 300 along the x, y, and z axis directions, as shown in image 3 As shown, the cell 300 of the metal lattice structure is composed of an outer skeleton 302 and an inner skeleton 301. The outer skeleton 302 is a regular hexahedral hollow structure formed by connecting a plurality of ribs, and each surface of the regular hexahedral ho...

Embodiment 2

[0036] The method for preparing the metal and polymer composite layer materials involved in the upper and lower layers of the bulletproof armor may include:

[0037] 1) Using 3D printing, the metal raw material is made into a metal lattice structure, in which the metal lattice structure is a flat and regular continuous structure formed by extending and arranging multiple cells along the x, y, and z axes. The cells of the metal lattice structure are composed of an outer skeleton and an inner skeleton. The outer skeleton is a regular hexahedral hollow structure connected by multiple ribs, and the diagonal lines of each surface in the regular hexahedral hollow structure are also connected with Ribs, the inner skeleton is a regular octahedral hollow structure formed by connecting the intersection points of the diagonal lines of the outer skeleton as corner points by a plurality of ribs, the intersection points of the diagonal lines on each surface of the outer skeleton and the corr...

Abstract

The embodiment of the invention provides a bulletproof armor comprising a metal lattice structure. The bulletproof armor comprises an upper layer, a middle layer and a lower layer, wherein the middlelayer is a ceramic composite material layer, the upper layer and the lower layer are both metal and polymer composite material layers, and each metal and polymer composite material layer is a composite material layer formed by completely coating a single-layer or multi-layer metal lattice structure with a polymer material. Each metal lattice structure is formed by extending a plurality of cell elements in the x-axis, y-axis and z-axis directions, and each cell element structure is composed of an outer framework and an inner framework. The bulletproof armor has the advantages of being lighter in weight, higher in continuous impact resistance and capable of resisting continuous high-speed bullet impact.

Description

technical field [0001] The present application relates to the technical field of bulletproof armor, in particular to a bulletproof armor comprising a metal lattice structure. Background technique [0002] In order to improve the survivability in actual combat, modern aircraft usually need to install bulletproof armor on the key parts of the aircraft. An excellent armor protection system can better protect the main body of the aircraft and the safety of the people in it. At present, the main problem of existing bulletproof armor is the contradictory conflict between bulletproof effect and weight. To achieve a good bulletproof effect, it is often necessary to sacrifice weight, which limits the maneuverability of the aircraft. [0003] Patent CN201510250746.2 invented a method for preparing lightweight bulletproof armor. The armor adopts a sandwich structure. The core plate is an aluminum matrix composite material reinforced by silicon carbide and graphene. The face plate and...
