Problems solved by technology

[0003] These innovative materials and structures can achieve a good effect of resisting bullets, but there is still a problem. As we all know, bullets shoot at a high speed and have a lot of kinetic energy. When they hit and penetrate the bulletproof plate , the energy is transmitted to the bulletproof board, causing the surface of the board to be broken or dented, and the inner layer of the board is also dented and the instantaneous deformation is transmitted to the buffer layer and the human body. A large instantaneous deformation in a small area can easily cause damage to human tissues and bones. For example, the bulletproof insert plate is very good at resisting the shooting of bullets, but the wearer still suffers from rib fractures or internal organ damage

Abstract

The invention relates to the field of bulletproof equipment and discloses a bulletproof plate with a high-strength polyurethane/metal structure. The bulletproof plate comprises a metal bulletproof layer and a coating layer, wherein the coating layer coats the outside of the metal bulletproof layer, a lap joint agent is arranged between the metal bulletproof layer and the coating layer, and the coating layer is different in thickness on different surfaces of the metal bulletproof layer. different surfaces of the metal bulletproof layer are sprayed with polyurethane materials different in thickness so as to adapt to meet the requirements of reinforcement, toughening and buffering; shot bullets are well defensed, meanwhile the transient deformation caused by the kinetic energy of the shot bullets is buffered by utilizing the properties of the polyurethane, and the body tissues and bones of a wearer are protected against injury.

Description

technical field [0001] The invention relates to the field of bulletproof equipment, in particular to a high-strength polyurethane / metal structure bulletproof plate. Background technique [0002] At present, the more common metal plates used for bullet-proof inserts are mainly bullet-resistant steel plates, titanium alloy plates, aluminum alloy plates, zinc alloy plates, magnesium alloy plates, nickel alloy plates, or a combination of several of them. High-strength fiber It is mainly selected from aramid fiber, polyethylene fiber, glass fiber, polypropylene fiber, polyester fiber, nylon fiber, polyaromatic heterocycle such as PBO, PBT fiber or a combination of several of them. [0003] These innovative materials and structures can achieve a good effect of resisting bullets, but there is still a problem. As we all know, bullets shoot at a high speed and have a lot of kinetic energy. When they hit and penetrate the bulletproof plate , the energy is transmitted to the bulletpro...
