Description

Anti-puncture structure

This creation is about a kind of anti-puncture structure, especially one that can achieve anti-puncture effect on both sides.

The general protective clothing is mainly formed by stacking and bonding multiple fiber layers, and its bulletproof effect is limited, and because of the gap between each fiber layer, it is more likely to be penetrated by sharp knives such as bayonet and fruit knife; and has bulletproof The effect of protective clothing is to have a ceramic plate and a bulletproof fiber barrier layer, so that after the bullet is injected from the front surface of the protective clothing, through the passivation, trapping, destruction and absorption of the ceramic plate to remove most of the bullet penetration force Energy, and then absorb the residual energy of the bullet through the barrier layer to achieve the bulletproof function. Therefore, in order to effectively achieve the bulletproof effect, it is necessary to have a sufficient thickness of the ceramic plate, but if this type of bulletproof clothing is used as a puncture-proof protective clothing, the overall weight of the bulletproof clothing will be increased, which is not suitable for ordinary people. ; Furthermore, the composition of the above-mentioned ceramic plate and barrier layer is mainly designed for the warhead is shot from the direction of the ceramic plate, and if it is installed in a backpack, leather bag or a separate protective plate, users often have The phenomenon of getting wrong on the positive and negative sides, as a result, still can not effectively achieve the protective effect.

In view of this, in order to provide a structure that is different from the conventional technology and to improve the above-mentioned shortcomings, the creator has many years of experience and continuous research and development and improvement, and this has created the original creation.

One of the purposes of this creation is to provide a puncture-proof structure by combining at least two first fiber layers and at least two second fiber layers on the upper and lower sides of an intermediate layer, and allowing a plurality of first fiber layers The structure in which one fiber closes a plurality of first gaps of another first fiber layer, and the plurality of second fibers of a second fiber layer closes a plurality of second gaps of another second fiber layer, so as to solve the conventional protective clothing Can not completely prevent the puncture breakthroughs such as sharp knives, the weight is too heavy, and can not be used on both sides, so as to effectively achieve the anti-puncture effect, reduce the weight to facilitate portable use, and can be arbitrarily correct when dangerous, Reverse use can produce a protective effect to ensure safe use.

For the purpose of the above creation, the anti-puncture structure provided in this creation includes at least two first fiber layers, an intermediate layer and at least two second fiber layers stacked in sequence. One of the at least two first fiber layers includes a plurality of first braided fibers, and the plurality of first braided fibers has a plurality of first gaps; the other first fiber layer includes a plurality of first fibers, The plurality of first fibers overlap to close the plurality of first gaps; one of the at least two second fiber layers includes a plurality of second woven fibers with a plurality of second gaps between the plurality of second woven fibers ; Another second fiber layer includes a plurality of second fibers, the plurality of second fibers overlap to close the plurality of second gaps.

In practice, the intermediate layer includes a plurality of horizontally adjacent ceramic sheets, and the intermediate layer may also be a metal sheet.

In practice, the ceramic sheet is a quadrangular plate sheet, and the four sides of the ceramic sheet are inclined surfaces extending toward the other end surface from one end surface of the ceramic sheet, respectively.

When implemented, the creation further includes a coating layer, which covers the outer surface of the middle layer. The coating layer can also be coated on at least two first fiber layers, an intermediate layer and at least two second fibers The outer surface of the dimension layer.

In practice, the thickness of the ceramic sheet is between 3 and 10 mm.

In practice, the first braided fiber, the first fiber, the second braided fiber and the second fiber system are high-elasticity and high-tension fibers.

In order to have a more in-depth understanding of this creation, I will elaborate on it later:
