Problems solved by technology

However, this setting is not fully utilized in the early stage of projectile impact, that is, when the energy of the projectile is maximum, so that the projectile still has a very large impact potential energy after breaking through the hard layer of the outer layer, making the bulletproof ability not high.

Embodiment 1

[0016] The alloy aluminum plate and high-strength nylon silk of the BPV-Ⅰ bulletproof vest are made as Figure 1 to Figure 7The bulletproof vest comprises two layers of composite bulletproof layers, respectively the first composite bulletproof layer and the second composite bulletproof layer, the first composite bulletproof layer is composed of the first hard bulletproof layer 1 and the first soft bulletproof layer 2, and the second The composite bulletproof layer is composed of a second hard bulletproof layer 3 and a second soft bulletproof layer 4. The first hard bulletproof layer 1 is composed of several hard sheets 5 protruding in the direction against the ballistic direction. The second hard bulletproof layer The bullet-proof layer 3 is made of a hard sheet 5 without curvature or a plurality of hard sheets 5 protruding against the ballistic direction. The hard sheet 5 is an alloy aluminum plate. The upper and lower adjacent hard sheets 5 are hingedly connected. One side...

Embodiment 2

[0018] Different from Example 1, the outer tactical vest and the KM-2 Kevlar lining (or needle-punched nonwoven felt) using the "Interceptor" body armor weigh a total of 3.8kg, and two pieces of 1.8kg each are added. The boron carbide ceramic plug-in plate has a total weight of 7.4Kg and a protection level of Ⅳ (refer to the American NIJ standard). Make the structure identical with embodiment 1, as Figure 1 to Figure 6 , but the hard sheet 5 is a boron carbide ceramic plate. The first hard bulletproof layer 1 and the second hard bulletproof layer 3 have the same thickness, which is 15mm. The first soft bulletproof layer 2 and the second soft bulletproof layer 4 are made of KM-2 Kevlar or needle-punched nonwoven felt with a thickness of 17mm. With reference to NIJ, the body armor made according to the present invention can defend against (high shot, low shot, flat shot) 30-caliber armor-piercing projectile (U.S. military M2 AP), with a projectile weight of 10.8g and a minimu...

Embodiment 3

[0020] Adopting a body armor that was originally up to level 4 with reference to the GA141-2010 police body armor standard was re-prepared according to the structure of the present invention and raised to level 5 (high shot, low shot, flat shot), which can be lower than the threat of the Type 56 7.62mm semi-automatic rifle. Specifically, two silicon carbide plates of 1.63kg, two layers of needle-punched non-woven felt, each 17mm, and the total weight of the body armor is 5.15kg. According to GA141-2010 test, it can also block the warhead, and the depth of the depression is 5mm smaller than the original 23mm.

Abstract

The invention discloses a bulletproof vest. The bulletproof vest comprises two composite bulletproof layers, and the composite bulletproof layers are composed of hard bulletproof layers and soft bulletproof layers from outside to inside in the ballistic direction; each hard bulletproof layer is formed by hinging a plurality of hard sheets protruding towards the direction against the ballistic direction, and metal wire meshes woven transversely and longitudinally are clamped between the hard sheets. According to the bulletproof vest, the arrangement of one composite bulletproof layer composed of one hard bulletproof layer and one soft bulletproof layer in the past is changed, the composite bulletproof layers are arranged to be formed by continuously arranging the multiple hard bulletproof layers and the multiple soft bulletproof layers without changing the overall thickness, and therefore the absorbing and buffering effect on the projectile body energy is improved, and the bulletproof effect is better; when impacted by projectile bodies, the hard sheets can rotate around pin shafts or move vertically, the moving freedom degree of the surface layer of the bulletproof vest is improved, and the bulletproof ability of the bulletproof vest is improved.

Description

technical field [0001] The invention relates to the field of body armor, in particular to a body armor. Background technique [0002] Bulletproof Vest is used to protect the human body from damage caused by bullets or shrapnel. So far, composite bulletproof vests have been widely used, that is, lightweight ceramic sheets are used as the outer layer, and high-performance fiber fabrics such as Kevlar are used as the inner layer. The soft bulletproof inner layer, such as a single layer of non-weft cloth, can be used as the backbone structure of the soft bulletproof vest, and multi-layer pressing can be used as hard bulletproof materials such as bulletproof reinforcement plates. Most of the energy of the bullet body is in the impact. The fiber near the point or impact point is absorbed by excessive stretching or piercing to break the fiber; and in the needle-punched nonwoven felt, almost no fiber breakage occurs, and the needle-punched nonwoven felt is composed of a large number...
