Multifunctional thermoplasticity aramid fiber bulletproof tablet and bulletproof spine-resistant clothes thereof

Abstract

The invention belongs to the field of protective equipments, in particular to a multi-functional thermoplastic aramid fiber bullet-proof slice and a bullet-proof and stab-proof vest. The invention mainly solves the technical problems of low bullet-proof and blunt trauma-proof functions, and no stab-proof function existing in soft aramid fiber bullet-proof materials in the prior art, and provides a multi-functional thermoplastic aramid fiber bullet-proof slice and a bullet-proof and stab-proof vest not only with better bullet-proof and blunt trauma-proof functions, but also with very good stab-proof function. Meanwhile, the invention also solves the difficulties of high water and moisture absorption rate, and easiness in photodecomposition of the aramid fiber bullet-proof cloth in the prior art. The provided multi-functional thermoplastic aramid fiber bullet-proof slice and a bullet-proof and stab-proof vest has the functions of permanent water and moisture proof, and prevention of photodecomposition. The main technical proposal of the invention is that the aramid fiber bullet-proof cloth is composited with the thermoplastic resin; the resin evenly penetrates on the surface of the aramid fiber bullet-proof cloth and fills in the pores of filament bundle binding points, and is shaped into a multi-functional thermoplastic aramid fiber bullet-proof slice through thermoplastics.

Description

technical field [0001] The invention belongs to the field of protective equipment. In particular, it relates to a multifunctional thermoplastic aramid bullet-proof sheet and bullet-proof and stab-proof clothing thereof. Background technique [0002] Ordinary soft aramid bulletproof clothing is mostly composed of aramid woven bulletproof fabric or one-way bulletproof fabric laminated. Its main advantage is that it is light in weight and soft, and it is more comfortable to wear than hard bulletproof clothing. However, the soft aramid bulletproof cloth has the following defects: [0003] 1. During the ballistic process of the aramid bulletproof fabric, only a few bundles of fiber tows orthogonal to 0° / 90° in the impact point are under force, while most of the oblique fibers at off-angles are idle; and Soft aramid bulletproof cloth has a large amount of deformation, which not only greatly weakens the resistance effect of aramid fiber to the transmission and absorption of proj...

AI Technical Summary

Problems solved by technology

[0003] 1. During the ballistic process of the aramid bulletproof fabric, only a few bundles of fiber tows orthogonal to 0° / 90° in the impact point are under force, while most of the oblique fibers at off-angles are idle; and Soft aramid bulletproof cloth has a large amount of deformation, which not only greatly weakens the resistance effect of aramid fiber to the transmission and absorption of projectile impact energy, but also produces deep concave craters on the back, resulting in fatal non-penetrating blunt injuries to the human body

[0004] Even if the aramid bulletproof fabric is sewn with anti-blunt unit units, the bulletproof and anti-blunt effects are still not obvious, and it will affect the wearing comfort of the bulletproof clothing

[0005] In short, the current soft aramid bulletproof clothing can only passively rely on increasing the number of layers of aramid bulletproof fabric to improve the bulletproof and anti-blunt injury functions, which not only increases the quality of the bulletproof clothing but also increases the cost. After the anti-blunt trauma unit is sewn on, it will make the laminate stiff and limit the freedom of movement of the human body

[0006] 2. Aramid bulletproof fabric is a warp and weft orthogonal woven fabric, and its fiber bundles will be displaced when it is horizontally squeezed, which will not only directly reduce the bulletproof function, but also cannot resist damage from sharp objects such as daggers, sharp knives, especially needle cones, etc. attack;

In the whole process of storage, transportation and production, use or storage of aramid bulletproof clothing, the whole process cannot be protected from light, which leads to the degradation of aramid fiber, resulting in the decline of bulletproof function and service life
