A Composite Bulletproof Plate for Armor

Abstract

A composite bulletproof plate for armor, including a protective plate and several groups of unit bodies, each group of unit bodies includes a base and a basic micro-element structure; the base is set as a U-shaped structure, and the two sides of the concave structure of the U-shaped structure There are positioning grooves on the inner wall of each unit, and the basic micro-element structure is put into the concave structure of the base to form a unit body, and the basic micro-element structure protrudes from the base to lay out; the U-shaped bottom of the adjacent unit body base is isolated by a buffer rod , and the gap between the protective plate and the unit body and the buffer rod is filled with adhesive; in the length direction, adjacent unit bodies are arranged repeatedly at intervals, and the unit bodies at the left and right ends pass through the buffer rod and the left and right inner walls of the energy-absorbing cavity touch. The composite bulletproof plate used on the armor mainly plays the role of energy absorption when it is impacted. First, the aramid fiber guard plate is used for blocking and buffering, and then the ceramic matrix structure works to absorb energy and consume most of the energy. , to achieve a good energy absorption effect.

Description

technical field [0001] The invention belongs to the technical field of cushioning and energy-absorbing protection, in particular to a composite bullet-proof plate used on armor. Background technique [0002] With the development of weapons and equipment and the needs of military combat missions, there are increasingly higher requirements for the maneuverability, protection performance and use performance of armored vehicles. Among them, the protection performance, as the main safety guarantee, needs to be paid more attention to. At present, the armor materials that can take into account bulletproof are still mainly special steel plates, and the density of metal materials is relatively high. The application of this material will greatly increase the weight of the armored vehicle itself, and will reduce the mobility and flexibility of the armored vehicle. Its comprehensive anti-ballistic performance is not ideal. [0003] At present, the research on metal backplanes based on...

Problems solved by technology

However, at present, most bulletproof panels made of these materials are made of superimposed panels of different materials, which do not have great advantages in structure, and only rely on the properties of materials to directly work, and the bulletproof performance is not very good, and this If this type of composite bulletproof plate is damaged by impact, it cannot be partially repaired and needs to be replaced as a whole, which will greatly increase the repair cost

[0004] The Chinese invention patent "A Bulletproof Board and Its Manufacturing Method" (Patent No.: CN108759570A) discloses a bulletproof board and its manufacturing method, wherein the bulletproof board includes: a ceramic layer, a connecting layer, a polyethylene fiber layer, and an adhesive layer ; Several polyethylene fiber layers are stacked from top to bottom, adjacent polyethylene fiber layers are bonded by bonding layers, each polyethylene fiber layer is pressed and formed by lamination, and any polyethylene fiber layer has several mutually parallel In the two adjacent polyethylene fiber layers, the fiber filaments of one polyethylene fiber layer are intersected with the fiber filaments of the other polyethylene fiber layer, and the ceramic layer is arranged through the connecting layer and the lamination. A number of polyethylene fiber layers are composited together, and the surface of the connecting layer in contact with the ceramic layer and the polyethylene fiber layer is a rough surface; the invention enhances the adhesion strength of the ceramic layer by setting the connecting layer, but its structure is single, and its bulletproof performance Weak, and after the bulletproof plate is damaged by impact, it cannot be repaired locally
