Problems solved by technology

At present, Western developed countries such as the United States and Europe have been equipped with high-performance fiber bulletproof materials. The application of aramid bulletproof materials in my country started relatively late, and is still at a disadvantage compared with foreign countries. In particular, domestic aramid fibers still have certain defects in performance stability. , limiting the domestic development of aramid bulletproof materials

Abstract

The invention discloses a method for preparing a light-weight aramid fiber composite non-weft cloth bulletproof chip. The aramid fiber composite non-weft cloth bulletproof chip is made of aramid fiber after being stretched and arranged in a uniform, parallel and straight manner. It is glued and dried to obtain aramid fiber composite non-weft fabric. By adjusting the parameters of the production equipment, aramid fiber composite non-weft fabrics with different surface densities are obtained; by increasing the number of compounding times of aramid fiber composite non-weft fabric , to make a multi-layer composite aramid fiber composite non-weft fabric; the prepared aramid fiber composite non-weft fabric with different surface densities and different composite layers is combined to make a bulletproof chip, and the lightweight aramid fiber in the present invention Lun fiber composite non-weft cloth ballistic chip has the advantages of good cushioning capacity, bullet resistance, shock resistance and good flame retardancy. At the same time, it has the advantages of light weight, portability, reducing personnel load and improving combat efficiency of combatants.

Description

technical field [0001] The invention belongs to the field of bulletproof protective products, and relates to a method for manufacturing a bulletproof chip, in particular to a lightweight aramid fiber composite non-weft cloth made of different surface densities and different composite layers. The preparation method of the non-weft cloth bulletproof chip. Background technique [0002] In order to prevent the damage of bullets to the human body, body armor has been developed both at home and abroad. Body armor is an essential life protection equipment for combatants, especially the demand for body armor products is increasing year by year. But current body armor is made of hard bulletproof chips that lack flexibility, and those made of flexible materials lack strength. At present, Western developed countries such as the United States and Europe have been equipped with high-performance fiber bulletproof materials. The application of aramid bulletproof materials in my country s...
