Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention The present invention relates to a bulletproof and anti-piercing textile material, including bulletproof clothing, knife-proof clothing,
The present invention aims to provide textile materials suitable for use in anti-piercing clothing, bulletproof nets, bulletproof shields, ships, tanks, armored vehicles and other vehicles or aircraft, storage tanks and other buildings, etc.

(Industrial Application Field) Bulletproof and puncture-proof knitted fabrics used for bulletproof and puncture-proof clothing, armor, ships, vehicles, aircraft, and building wall materials.

(Prior Art) Steel plates or chains with a braided structure are generally used as bulletproof clothing or armor materials.

That is, steel plates, braided chain materials, etc. are used to protect the human body from bullets fired by firearms, and also to prevent damage to vehicle bodies. In addition, luxury cruiser, luxury lightweight,
Glass fiber and carbon fiber are used in high-end motorboats and the like.

(Problems to be Solved by the Invention) In products using steel plates or braided chain materials as described above, the shear strength etc. can be increased by increasing the thickness of the steel plate, the diameter of the wire material constituting the chain, and its density. Although bulletproof properties can be obtained, the weight is large, which inevitably limits the wearer's movements. In particular, steel plates are extremely rigid and restrict movement. In addition, a lighter version of this cannot provide adequate protection against being stabbed by a knife. In other words, even if the materials and crystal structures of steel and other metals have been improved in recent years, the performance of guns and explosives based on the strength of these metals has also improved, resulting in improvements in the penetrating power of bullets. However, in the end, a thickness comparable to the diameter of the bullet to be protected is required for protection, and anything that does not reach this level cannot provide effective protection.

Ships and vehicle bodies made of glass fiber are not sufficiently resistant to vibrations and impacts, and there is a high possibility that the bottom of the ship will be damaged or cracked, resulting in many serious accidents.

Therefore, even if these conventional products have a bulletproof effect as prescribed, they do not necessarily require sufficient personal protection in cases of puncture or impact caused by knives, etc. It has no choice but to be subject to considerable restrictions. That is why, for example, police officers and security guards often suffer accidents resulting in death or injury while wearing bulletproof clothing, and in particular cannot provide effective protection against penetration by knives.

"Structure of the Invention" (Means for Solving the Problems) The present invention has been devised after repeated studies to solve the problems of the conventional products as described above, and is as follows.

1. A strong composite strip made of a strong metal wire and a strong fiber material, in which either the metal wire or the fiber material is used as a core material, and the other is used as a covering material, and the outer surface of the core material is covered with 11M1. A bulletproof and puncture-proof knitted material characterized by its strong shape.

2. The strong metal wire consists of a plurality of duralumin wires or wires or stainless steel wires or wires, and the strong fiber material is one or more of aramid fibers, carbon fibers, Manila hemp, etc., and these metals Either wire or fiber material is used as a core material, and the other is used as a covering material to form a strong composite strip that is braided and covered in a crisscross pattern on the outer surface of the core material, and the tough composite strip is knitted or woven to form a knitted or woven version. A bulletproof and puncture-proof knitted or woven material, characterized in that the knitted or woven plate is treated with a resin.

(Function) A strong composite strip is made of a strong metal wire and a strong fiber material, and one of the metal wire and the fiber material is used as a core material, and the other is used as a covering material and is braided and covered on the outer surface of the core material. The braided structure on the outer surface forms irregularities on the circumferential surface.

As described above, by weaving and weaving the strong composite stripes with unevenness on the circumferential surface, the strong composite stripes knitted with the unevenness form a relationship in which they are mutually engaged and positioned at their respective joining parts. In addition, the strong composite strip has a braided covering layer on its outer surface and a bending structure formed by the braided fabric, so that it expands and contracts slightly when it receives an impact from a bullet, a knife, or the like. Therefore, the impact force caused by such bullets, blades, etc. can be received in a cushioning manner by utilizing the tensile strength which is clearly higher than the shear strength of the metal wire and fiber material.

It goes without saying that the sheathing material is braided with multiple threads, but the core material, whether made of metal wire or fiber material, should be braided in the form of a bank or braid. By doing so, the core material itself can be stretchable in the axial direction, and the bond between the core material and the covering material can be improved. In particular, such high elasticity and bondability can be achieved by forming a bank-like wire by eliminating multiple ends.

By using dural flexible wire as a strong metal wire, lightness is ensured regardless of the use of metal wire, and if a certain amount of weight is acceptable, stainless steel wire is used.

The strength of the fiber material is ensured by using materials such as aramid fiber, carbon fiber, and manila hemp.

The diameter of the core material and strong composite stripes, as well as the thickness of the textile material, can be selected as appropriate for each bulletproof purpose, and when the target is a handgun bullet, the thickness of the textile material alone is 2.0. ~3.0 ml (approximately 5.0 W including the resin-treated layer on the inner surface) is sufficient, and in the case of larger bullets for rifles and bags, it should be thicker.

(Example) To explain the specific implementation B of the present invention as described above, some examples of the strong composite strip lO used in the present invention are as shown in Figure 1, and the one in Figure (A) duralumin wire or wire or stainless steel wire or wire 11 is combined with a plurality of strong fibers 12 such as aramid fibers, carbon fibers, or manila hemp around the core material 1, and duralumin wire or wire or stainless steel wire or wire As shown in the figure, the wires 11 are made up of three or more wires, for example, about 7 to 10 wires, each of which is assembled into a twisted shape. It is rare. In the case of FIG. 1(B), the wire 11 made of twisted plural wire rods is
The covering material 2 is made by braiding tough fibers 12 in the form of a braid to the core material 1 which is bonded as a disciplinary letter in the same way as in the case of .

Furthermore, in the case of FIG. 1(C), the core material 1 is made by aligning a plurality of strong fibers 12 such as aramid fibers in parallel, and a tough fiber is added to the circumferential surface of the core material 1. The metal wires 11 are assembled in a criss-cross pattern as the covering material 2 in the same manner as in the case shown in FIG.

That is, regarding the tough composite strips 10 shown in FIG.
Alternatively, it is clear that the braided structure of the strong fibers 12 forms a certain degree of unevenness, and the covering material 2 made of such braid or crossing also forms similar unevenness on the inner surface and engages with the core material 1. Therefore, as shown in FIG. 1(C), it effectively engages with the strong fibers that are a group of parallel stripes, and the locking position is fixed. In the case of Figures (A) and (B) in which a twisted or braided structure is adopted on one side of the core material, unevenness is also formed on the one side of the core material, and the inner surface of the covering material 2 as described above The locking and positioning effect between the two is higher. Moreover, the assembled and braided structure described above gives flexibility in the length direction and appropriate elasticity to the elastic composite strip 10 constructed as a whole, and such composite strips 10 are arranged vertically and horizontally. It is clear that the resulting weaving or knitting is possible.

Some examples of the knitted fabric material 20 of the present invention constituted by the composite strip IO obtained as described above are shown in FIGS. 2 and 3.
It is shown in cross section in the figure. In other words, the elastic composite strips 10 as described above are arranged vertically and horizontally to form a woven structure, but as described above, the composite strips 10 having flexibility and appropriate elasticity facilitate the 'Islam. It is possible to form a close woven structure such as Moreover, since the fabric woven in this way forms a mutually engaged relationship with the above-mentioned uneven structure on the outer surface of each composite strip 10, the woven structure itself becomes stable.

As shown in FIG. 2, a resin-treated layer 6 of synthetic resin latex such as foamed urethane or natural latex is formed on one or both sides of the textile material 20 knitted into a plate shape, or as shown in FIG. The resin-processed layer 6 can be formed by mixing short fiber chops 7 made of carbon fiber, aramid fiber, etc. with a length of 10 wm or less into synthetic resin latex or natural latex.

The composite strip 10 itself has irregularities on its circumferential surface, and the knitted or woven material 20 obtained by bending and weaving such a composite strip 10 has larger irregularities on its surface. The resin processed layer 6 formed in the above manner is also stably layered as shown in FIG.

The fabric obtained in the above manner is stable due to the convex-concave structure of the composite strip 10, and the composite strip 10 has some flexibility or elasticity, so it can be used for bullets, etc. This strong fiber material absorbs the impact force in a cushioning manner when it receives an impact caused by a knife or is punctured by a knife. 12 also provides a buffering effect, and as a result of the combined effect of such a buffering effect and because the weaving position of the strips 10 is stable and the structure is stable, a strong impact force is ultimately applied to the strong metal. The impact force is appropriately reduced in the state where it is received by the wire 11 or lla, and the impact force is received with the tensile strength that is advantageously required for such a metal wire, so it is sufficient to withstand the strong impact force caused by bullets, the tip of a knife, etc. It becomes possible to respond.

The thickness of the woven material is appropriately determined depending on the target bullet. For example, in the case of a net for bullets, a composite strip 1 with a diameter of 10 to 15 mm is used.
0 is used as a net.

Specific manufacturing examples and test results of the products according to the present invention will be described below.

It was a product of am.

A penetration test was conducted on each of the above-mentioned manufacturing examples by firing a hunting rifle at close range of 5 m, but no bullets or fragments were found to penetrate, and impact traces were observed on the surface side. It was only a matter of time.

In addition, we repeated the puncture test using a double-edged mountain climbing knife with the full force of an adult, but the result was that only a few puncture marks were left on the surface, confirming that it could withstand being punctured by a knife. Ta.

``Effects of the Invention'' According to the present invention as explained above, it is possible to provide a fabric material that effectively prevents penetration by bullets, etc., can adequately withstand puncture by a knife, and is strong against strong metal wires. It is knitted using a strong composite strip made of three-dimensional composite fiber materials, and the flexibility and elasticity of the strong metal wire in the strong composite strip are determined by the relationship between the strong composite strips in the knitting structure. Since the strength of the strong metal wire is moderately high under bonded and fixed conditions, it has both the impact resistance effect due to the advantageous tensile strength of such a strong metal wire and the material and structural cushioning effect, and is relatively lightweight and has a thin layer. The above-mentioned bulletproof and anti-piercing functions can be achieved by using knitted materials, and therefore, they can be lightweight and advantageously used not only as bulletproof shields, but also in armored vehicles, aircraft, ships, structures, etc. This invention has a great effect industrially.
