Novel light body armor with kinetic energy absorption structure

Abstract

A novel light body armor with a kinetic energy absorption structure comprises a coat, a body armor body, a lining and the kinetic energy absorption structure, wherein the coat is arranged on the outer side of the body armor body; the lining is arranged on the inner side of the body armor body; the body armor body is manufactured by processing high-performance fibers; the kinetic energy absorption structure adopts a design structure in which a fire-retardant liquid cooperates with an elastic sealing unit; the elastic sealing unit is filled with the fire-retardant liquid; and the kinetic energy absorption structure is movably mounted outside the lining. The biggest difference between the novel light body armor and a traditional buffer structure is that the novel light body armor can recover automatically and is reduced in later-stage maintenance cost; the novel light body armor is simple in structure, has a good kinetic energy absorption effect, forms a gentle large-area fluid kinetic energy impact on a human body, and reduces harm to the human body; and the novel light body armor is unique in design structure, reduces damage caused by compressed foam products to the ecological environment, and saves the costs of later-stage maintenance, storage and the like.

Description

technical field [0001] The patent of the present invention relates to the technical field of buffer structure of body armor, especially a new type of lightweight body armor with kinetic energy absorbing structure. It has a good kinetic energy absorption effect, and can also achieve repeated use of the buffering effect, without causing waste of materials and damage to the ecological environment. Background technique [0002] In the existing design of soft body armor, it is basically made of high-performance elastic fiber. The fiber absorbs the kinetic energy of bullets to effectively protect bullets and shrapnel. There are five main ways for fiber soft body armor to absorb energy: [0003] 1. Tensile deformation of the fabric: refers to the deformation in the direction of the bullet incident and the tensile deformation in the area near the incident point; [0004] 2. Destruction of fabric: including fiber fibrillation, fiber breakage, knot of yarn structure and disintegratio...

AI Technical Summary

Problems solved by technology

[0009] Kinetic energy bullets and shrapnel will produce a large kinetic energy impact effect when hitting the body armor. Although it will not penetrate the body armor, its strong kinetic energy transmission will still cause certain damage to the wearer. Traditional body armor adopts thicker The foam buffer layer is used for a certain buffering effect, that is, the absorption effect of kinetic energy, but the structure is used for one time, that is, it cannot recover by itself after elastic deformation, and needs to be replaced accordingly; moreover, the thickened foam layer has very low elastic deformation, giving The flexibility to operate using personnel combat techniques imposes certain limitations;
