Embodiment 1

[0012] Example 1: 130 layers of high-strength and high-modulus polyethylene non-woven fabrics were hot-compressed and laminated to obtain a product with a thickness of 10 mm and a weight of 1.1 kg. After testing, it can resist the 51-B (7.62mm) steel core bullet fired by the 79-type submachine gun with a bullet speed of 500m / s, and meets the level 5 standard of GA141-2001.

Embodiment 2

[0013] Example 2: 270 layers of high-strength and high-modulus polyethylene non-woven fabrics were hot-compressed and laminated to obtain a product with a thickness of 20 mm and a weight of 1.5 kg. After testing, it can resist the M80 bullet (7.62mm 51-B steel core bullet) with a bullet velocity of 855m / s, and meets the NiJ0101.04III level standard formulated by the American Institute of Justice.

Embodiment 3

[0014] Embodiment 3: each 50 pieces of single-sided polyethylene bulletproof breastplates and chamfered multi-curved polyethylene bulletproof breastplates are tried on by 100 experimenters at the same time, and the statistical results show that the multi-curved polyethylene bulletproof breastplates are tried on. 50 people feel comfortable to wear and reflect well.

Abstract

The invention is a multi-curve surface polyethylene bulletproof chest guard plate. Its transection is arc shape; longitudinal section is S shape, four angles are chamfer or partial chamfer or non-chamfer. It forms utilizing strength high-mode polyethylene laid fabric according to design requirement of laminated superposition hot pressing recombination.

Description

technical field [0001] The invention belongs to a bulletproof breastplate for preventing bullet wounds, in particular to a multi-curved polyethylene bulletproof breastplate. Background technique [0002] The bulletproof chest plate is a necessary product commonly used by army commanders and public security officers to protect their own safety in anti-terrorism and anti-emergency incidents. It is inserted into the front and rear plate pockets of the body armor for use. At present, flat or single-curved bulletproof chest plates are generally used, and they have the following three major defects: ① uncomfortable to wear; ② most of them use ceramic sheets and polyethylene sheets or metal sheets and polyethylene sheets, the production process is complicated and the cost is relatively high. High; ③ The anti-ballistic performance is not good, and it may cause secondary damage or accidental injury due to secondary ricochets. Contents of the invention [0003] In order to overcome...
