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 preparation method for a light bomb-proof aramid fiber composite non-woven fabric chip. The preparation method for the bomb-proof aramid fiber composite non-woven fabric chip includes: spreading aramid fibers, uniformly and straightly arraying in parallel, coating, drying to obtain aramid fiber composite non-woven fabric, and regulating parameters of production equipment to produce the aramid fiber composite non-woven fabrics with different surface density; preparing multilayer composite aramid fiber composite non-woven fabric through increasing the compositing times of the aramid fiber composite non-woven fabric; combining the aramid fiber composite non-woven fabrics with different surface density and different composite layer number to obtain the bomb-proof chip. The light bomb-proof aramid fiber composite non-woven fabric chip has good buffer ability and fire resistance, is resistant to bomb and vibration, is light and convenient to carry, enables the personnel load to be reduced, and enables the fighting efficiency of the fighter to be improved.

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-woven 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 starte...
