Example Embodiment

[0016] Example 1

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

[0018] The aramid fiber is wound in parallel on a winder, and then the fiber is immersed in the above-mentioned glue solution, and the fiber is spread through a special spinning device. In this embodiment, the above-mentioned adhesive is used. After dipping the glue, the glue is evenly spread with a squeegee, and dried under an electric resistance wire at 50°C. After it is completely dried, the cloth sample is rotated 90°, and the fiber filaments and The cloth-like fiber filaments are combined orthogonally to obtain a two-layer interlaced cloth pattern. The structure of the obtained product is [0° / 90°], and the surface density of the cloth sample is 200g / m 2 . Cut the cloth swatch into a 400mm×400mm square cloth swatch, remove the PE film, layer the 2 layers of cloth sw...

Example Embodiment

[0019] Example 2

[0020] Change the crosslinking agent in Example 1 to 60g, and change the surface density of the fabric to 200g / m 2 The remaining conditions are the same as in Example 1. Use 54 type 7.62mm pistol, 51 type 7.62 pistol (lead core), according to GA141-2010 bulletproof level 2 test, the results are shown in Table 1.

Example Embodiment

[0021] Example 3

[0022] In Example 1, the structure is changed to 20 layers of [0° / 90°] cloth pattern + 2 layers of [0° / 90° / 0° / 90°] bulletproof sheet + 3 layers of [0° / 90°] cloth pattern Made into 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...
