Anti-sag bulletproof structure

This creation is about an anti-sag bulletproof structure, especially one that can effectively reduce the amount of dent deformation generated when a bullet is injected, so as to protect the body from the bulletproof body.

At present, the common body armor structure mainly includes surface layer, ceramic plate and anti-elastic fiber board which are sequentially bonded. The surface layer is a sheet-shaped bulletproof fiber, the ceramic plate is composed of a plurality of butt-joined ceramic sheets, and the anti-elastic fiber board is formed by stacking a plurality of bulletproof fibers. When the bullet is injected from the surface of the bullet-proof vest, the majority of the energy of the warhead penetration force is removed by passivation, trapping, destruction, and absorption of the ceramic plate, and the residual energy of the bullet is absorbed through the anti-ballistic fiberboard to achieve bulletproof Features.

The above-mentioned bulletproof vest structure can achieve the effect of absorbing the energy of the bullet, but in actual use, since the bullet penetrates the surface layer and impacts the ceramic plate, the instantaneous impact force on the ceramic plate is too large, and the ruptured ceramic piece is pressed. The anti-elastic fiberboard makes the bullet-resistant fiberboard sag greatly. In this way, even if the anti-ballboard is not penetrated and injected into the human body, the human body will still be injured after the bullet-resistant fiberboard is greatly depressed, for example: deep And the ribs break the ribs, or the viscera and the internal organs rupture, and greatly reduce the effect of wearing the body armor to protect the human body.

Therefore, the industry needs an anti-sag bulletproof structure, which can buffer the energy of the bullet injection and effectively reduce the amount of dent deformation generated when the bullet is injected, so as to create a body armor that can protect the human body.

The amount of deformation generated by recessing the ballistic resistant fiberboard.

In the above, the method further includes a cross cladding layer covering the ceramic board, the anti-ballistic fiber board and the anti-recess composite layer. Wherein the middle portion of the cross cladding layer is attached downwardly to the top surface of the ceramic board, and the four wing portions of the cross cladding layer are respectively folded downward to respectively cover the ceramic board, the anti-ballistic fiber board and the The four sides of the anti-cavity composite layer are bent inwardly and inwardly in the horizontal direction after passing through the four sides, so as to be laminated and laminated on the bottom surface of the anti-cavity composite layer. The cross wrap The material of the layer may be a fiber cloth which is woven with Kevlar fibers or glass fibers or other fibers having similar ballistic properties, preferably Kevlar fibers.

In the above, the ceramic plate is composed of a single piece of ceramic piece or composed of a plurality of ceramic pieces, and the plurality of ceramic pieces may be adjacent to each other; the ceramic piece is made of alumina, titanium boride, tantalum carbide, boron carbide. Or one of the grouped groups.

In the above, the anti-elastic fiberboard is composed of a single piece of fiber cloth or a plurality of stacked and heat-pressed fiber cloths; the fiber cloth is made of Kevlar fiber or glass fiber or other fiber having similar anti-ballistic properties. Woven, preferably Kevlar fiber.

The anti-cavity composite material layer used in the creation can reduce the excessive deformation of the anti-elastic fiberboard when the bullet is injected to cause the ceramic sheet to rupture, and the cross-cladding layer can prevent the ceramic plate from being broken due to the crack. Dispersing and absorbing the residual energy of the bullet can greatly reduce the amount of deformation of the material layer to effectively avoid harm to the human body.
