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

Embodiment 1

[0017] First, weigh 1000g of acrylate adhesive and 10g of cross-linking agent triglycidyl isocyanurate (TGIC), add the cross-linking agent evenly into the glue, and mix the glue well for later use.

[0018] The aramid fiber is wound in parallel on the winding machine, and then the fiber is immersed in the above glue solution, and the yarn is spread by a specific spinning equipment. In this example, the above-mentioned adhesive is used. After dipping the glue, spread the glue evenly with a squeegee, and dry it under the electric resistance wire at 50°C. Orthogonal compounding of the cloth sample fibers results in two interlaced cloth samples. The corresponding product structure is [0° / 90°], and the surface density of the cloth sample is 200g / m 2 . Cut the fabric sample into a 400mm×400mm square fabric sample, remove the PE film, stack the two layers of the fabric sample in the direction of [0° / 90°, 0° / 90°], put the laminated fabric sample into the mold, and use 50t press, pr...

Embodiment 2

[0020] Change the cross-linking agent in Example 1 to 60g, and change the surface density of the cloth sample to 200g / m 2 All the other conditions are the same as in Example 1. Adopt Type 54 7.62mm pistol, Type 51 7.62 pistol bullet (lead core), according to GA141-2010 bulletproof level 2 test, the results are shown in Table 1.

Embodiment 3

[0022] In Example 1, the structure is changed to 20 layers of [0° / 90°] cloth samples + 2 layers of [0° / 90° / 0° / 90°] bulletproof sheets + 3 layers of [0° / 90°] cloth samples Made bulletproof chips, 51 type 7.62 pistol bullets (lead core), according to GA141-2010 bulletproof level 2 test, the results are shown in Table 1.

Abstract

The invention provides a piece of novel body armor and relates to the field of individual protection. The body armor is mainly composed of aramid fiber laid fabric. Aramid fiber laid fabric materials prepared through a special technology are used as back blunt trauma preventing materials. Shooting tests prove that a body armor product prepared through the adoption of the structure is excellent in bulletproof performance, high in safety margin, light in weight, and capable of remarkably improving the fighting efficiency of war fighters.

Description

Technical field: [0001] The present invention relates to a new type of bulletproof clothing, and furthermore, relates to a bulletproof product applied to individual protection of individual soldiers. Background technique: [0002] Since the Kosovo War and the Gulf War, my country has paid more and more attention to the localization of military equipment. At present, my country still relies mostly on imports of such materials. Due to the shortage of supply worldwide, it has not only been expensive for many years, but also difficult to buy. Sometimes it can be bought. Some of them are also forced to sell other products by American companies, and the ordering conditions are very strict. At present, the high-performance fibers used in the bulletproof field are mainly aramid fibers and high-strength high-modulus polyethylene fibers. Due to the low melting point of high-strength and high-modulus polyethylene fiber, which is only 150°C, when it is penetrated by bullets, a large amo...
