Novel bulletproof material and body armor

Abstract

The invention discloses a novel bulletproof material and a body armor. The novel bulletproof material is characterized by being composed of a fiber braided fabric layer, a shear thickening liquid layer, an aerogel material layer and a protective sheath, wherein the protective sheath is provided with three hollow cavities, the fiber braided fabric layer, the shear thickening liquid layer and the aerogel material layer sequentially fill the three hollow cavities of the protective sheath. The provided novel bulletproof material has the characteristics of high bulletproof grade, light weight and the like, the body armor prepared from the bulletproof material has excellent characteristics of preventing bullet penetration and absorbing bullet impact waves, also has the wearing characteristics ofbeing light, soft, comfortable, heat-insulating, fireproof and the like, and has a huge market prospect.

Description

technical field [0001] The invention relates to the fields of bulletproof materials and bulletproof vests, in particular to the field of a novel bulletproof composite material containing aerogel and the field of a novel bulletproof vest containing aerogel. Background technique [0002] Body armor is personal protective equipment worn in a specific environment to ensure the survival of people. It mainly protects the front chest and back and prevents bullets and fragments from causing damage to important parts of the human body. Body armor should have two performances: (1) Functionality, that is, prevent bullets from entering the body, buffer and absorb the impact force and shock waves generated by bullets, and resist multiple shots; (2) Wearability, that is, light, soft and comfortable And the military and police have good combat maneuverability after wearing body armor. [0003] Bulletproof vests can be divided into three categories: (1) Hard body armor: special steel plate...

AI Technical Summary

Problems solved by technology

[0003] Bulletproof vests can be divided into three categories: (1) Hard body armor: special steel plates, super aluminum alloys and other metal materials or alumina, silicon carbide ceramics, etc. are used as the main bulletproof materials. Affect the combat mobility of the military and police, and the military and police only use it in very dangerous situations; (2) Soft body armor: mainly made of high-performance textile fibers (mainly aramid fibers and ultra-high modulus polyethylene fibers), using Textile structure, light and comfortable, the bulletproof level can only reach level II (GJB4300-2002 "Safety Technical Performance Requirements for Military Body Armor"), used by military and police when performing daily tasks; (3) soft and hard composite body armor: soft and hard composite The softness of body armor is between the above two types. It is lined with soft materials and hard materials are used as interlayer panels and internal reinforcement materials. It still has the problem of poor wearability of hard body armor.

[0004] How to solve the contradiction between the poor performance of hardware bulletproof clothing and the low bulletproof level of soft bulletproof clothing, and the development of new high-performance bulletproof clothing is a current research hotspot and difficulty
