Description

Technical Field

[0001] The utility model relates to the technical field of para-aramid bulletproof cloth, in particular to a high-toughness para-aramid bulletproof cloth. Background Art

[0002] Para-aramid bulletproof cloth is a special bulletproof material made of para-aramid fiber. Para-aramid, also known as poly(p-phenylene terephthalamide) fiber, has a highly ordered molecular chain structure, which gives it excellent physical properties, such as high strength, high modulus, excellent thermal stability and chemical stability. In the production process of bulletproof cloth, para-aramid fiber is woven or laminated to form a bulletproof layer with specific structure and performance. This bulletproof layer can effectively absorb and disperse the impact energy of bullets or shrapnel, thereby protecting the wearer from injury.

[0003] Existing aramid bulletproof cloth, such as the laminated aramid cloth disclosed in publication number CN205498243U, has the advantages of significantly reducing the number of stacked layers to reflect lightness, having an outstanding bulletproof effect to ensure safety, saving resources and reflecting economy and cheapness. However, this aramid cloth does not have an impact-resistant structure inside, and thus has poor effects on deceleration and impact reduction after a bullet is shot into it. Therefore, we propose a high-toughness para-aramid bulletproof cloth. Utility Model Content

[0004] The main purpose of the utility model is to provide a high-toughness para-aramid bulletproof cloth, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A high-toughness para-aramid bulletproof cloth comprises a bulletproof cloth body, wherein the bulletproof cloth body comprises a first aramid layer, a second aramid layer and a third aramid layer at the front and rear ends, wherein both ends of the first aramid layer are cross-knitted with first vertical braids and first horizontal braids, and multiple groups of first reinforcement areas are formed between the first vertical braids and the first horizontal braids, and both ends of the second aramid layer are cross-knitted with second vertical braids and second horizontal braids, and multiple groups of second reinforcement areas are formed between the second vertical braids and the second horizontal braids, and both ends of the third aramid layer are cross-knitted with third vertical braids and third horizontal braids, and multiple groups of third reinforcement areas are formed between the third vertical braids and the third horizontal braids.

[0007] Preferably, the first vertical braided strip, the first horizontal braided strip, the second vertical braided strip, the second horizontal braided strip, the third vertical braided strip and the third horizontal braided strip are all knitted from aramid fiber yarns.

[0008] Preferably, the areas of the first reinforcement area, the second reinforcement area and the third reinforcement area are arranged in decreasing order.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] In the utility model, a plurality of groups of vertical woven strips and horizontal woven strips are arranged and knitted in the first aramid layer, the second aramid layer and the third aramid layer in the bulletproof cloth body, which can form a plurality of groups of first reinforced areas, second reinforced areas and third reinforced areas with high impact resistance and high toughness inside after being woven, so that after the bullet-proof cloth is impacted by a bullet, the impact strength can be sharply reduced through the first reinforced areas, the second reinforced areas and the third reinforced areas, thereby improving the impact resistance effect of the bulletproof cloth body.

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0017] Embodiment 1:

[0018] like Figure 1-3As shown, the present embodiment provides a high-toughness para-aramid bulletproof cloth, including a bulletproof cloth body 100, the bulletproof cloth body 100 includes a first aramid layer 101, a second aramid layer 102 and a third aramid layer 103 at the front and rear ends, the first aramid layer 101 is further arranged at both ends to be cross-knitted with a first vertical braided strip 104 and a first horizontal braided strip 105, and a plurality of first reinforcement areas 106 formed between the first vertical braided strip 104 and the first horizontal braided strip 105, and the second vertical braided strip 107 and the second horizontal braided strip 108 are further arranged at both ends to be cross-knitted with a second vertical braided strip 107 and a second horizontal braided strip 108, and the second vertical braided strip 107 and the second horizontal braided strip 108 are further arranged to be cross-knitted with a second vertical braided strip 107 and the second horizontal braided strip 108. Multiple groups of second reinforcement areas 109 are formed between the horizontal woven strips 108, and third vertical woven strips 110 and third horizontal woven strips 111 are cross-knitted at both ends of the third aramid layer 103, as well as multiple groups of third reinforcement areas 112 are formed between the third vertical woven strips 110 and the third horizontal woven strips 111. The first vertical woven strips 104, the first horizontal woven strips 105, the second vertical woven strips 107, the second horizontal woven strips 108, the third vertical woven strips 110 and the third horizontal woven strips 111 are all knitted from aramid fiber yarns, and the areas of the first reinforcement area 106, the second reinforcement area 109 and the third reinforcement area 112 are arranged in a decreasing manner.

[0019] Specifically, the para-aramid bulletproof cloth is a special bulletproof material made of para-aramid fiber. Para-aramid, also known as poly(p-phenylene terephthalamide) fiber, has a highly ordered molecular chain structure, which gives it excellent physical properties, such as high strength, high modulus, excellent thermal stability and chemical stability. In the production process of the bulletproof cloth, the para-aramid fiber is woven or laminated to form a bulletproof layer with a specific structure and performance. The first aramid layer 101, the second aramid layer 102 and the third aramid layer 103 in the bulletproof cloth body 100 are made of a plurality of layers. The multiple groups of vertical woven strips and horizontal woven strips knitted are arranged in the polyamide layer 103, which can form multiple groups of high impact resistance and high toughness areas of the first reinforced area 106, the second reinforced area 109 and the third reinforced area 112 after weaving. After the bullet-proof cloth body 100 is impacted by a bullet, the impact strength can be sharply reduced through the first reinforced area 106, the second reinforced area 109 and the third reinforced area 112, thereby improving the impact resistance of the bullet-proof cloth body 100. At the same time, the impact resistance of the bullet-proof cloth body 100 will be better after multiple layers are stacked.

[0020] The working principle and use process of this utility model:

[0021] After the bullet is shot into the upper end of the first aramid layer 101 in the bulletproof cloth body 100, the first vertical braided strips 104 and the first horizontal braided strips 105 at the outer ends of the first reinforced area 106 will maintain the tension in the first reinforced area 106 after the first reinforced area 106 at the center is impacted, thereby reducing the impact force and impact speed of the bullet while increasing the tension in the first reinforced area 106. After the bullet passes through the first aramid layer 101, it will pass through the second reinforced area 109 and the third reinforced area 112 in the second aramid layer 102 and the third aramid layer 103 to reduce the subsequent continuous speed and impact force, thereby ensuring the impact resistance of the bulletproof cloth body 100 in use and ensuring its high toughness.

[0022] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
