Abstract

PROBLEM TO BE SOLVED: To obtain a bulletproof vest in which a weight can be reduced, an armoring performance can be improved and a piercing action by a knife, etc., can be prevented by impregnating many high strength fibers with a synthetic resin adhesive agent and integrating them in the bulletproofs vest formed by laminating many high strength fibers. SOLUTION: An armored vest is formed with a bulletproof vest main body 3 obtained by impregnating many high strength fibers 2 with a synthetic resin adhesive agent and integrating them and a cover 5 with which the bulletproof vest main body 3 is covered. The synthetic resin adhesive agent is composed of a linear saturated polyester resin. When a bullet pierces the cover 5 and collides with the bulletproof vest main body 3 and moves forward so as to twist and bits each of the high strength fibers, the rotation of the bullet is braked by many high strength fibers 2 so that piercing energy and collision energy are absorbed. Further, the rotation of the bullet is more strongly braked by the adhesive strength of the synthetic resin agent to stop the bullet.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bulletproof vest for protecting the body from bullets and the like, and more particularly to a bulletproof vest that is lightweight and can protect bullets having a high level of energy.

[0002]

2. Description of the Related Art Bulletproof vests using a laminate of high-strength fibers have been known in the past, and many fiber materials have been proposed, such as those using aramid fibers and those using high-strength polyethylene fibers. When bullets are shot into these high-strength fiber laminates, the shots fire,
A plurality of high-strength fiber fabrics will advance while twisting one by one while twisting, but the plurality of high-strength fiber fabrics will stop by stopping the rotation of the bullet and prevent penetration. ing.

[0003]

A bulletproof vest using a laminate of high-strength fibers as described above has the advantage of being flexible and allowing the wearer to freely move.
It was ineffective against bullets with high levels of energy fired from extremely powerful firearms such as Tokarev and Magnum and could not prevent its penetration. Therefore, in order to cope with powerful firearms such as Tokarev and Magnum, it is conceivable to increase the number of laminations in order to improve bulletproof performance. However, the weight and bulk are remarkably increased, and it is practically difficult to wear. Furthermore, a bulletproof vest using a laminate of high-strength fibers is extremely weak against piercing by a blade and can be easily pierced, and secures sufficient safety for a wearer against the blade. There was a problem that it was difficult.

In a conventional armor-proof bulletproof vest using a high-strength shell, bulletproof performance is improved by sticking a thick steel or steel tip, which is resistant to piercing by a cutting tool and the like. Powerful firearms such as the magnum can be dealt with, but there is a problem that the weight is significantly increased and the movement of the wearer's body is restricted.

Accordingly, the present invention provides a method of impregnating a large number of laminated high-strength fibers with a synthetic adhesive and integrating them.
It is an object of the present invention to provide a bulletproof vest that allows a wearer to freely move, improves weight and improves ballistic performance, and can also protect against piercing with a blade or the like.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and in a bulletproof vest formed by laminating a large number of high-strength fibers, the large-strength fibers are impregnated with a synthetic resin adhesive. A bulletproof vest characterized by being integrated as one. Further, the bulletproof vest is characterized in that the synthetic resin adhesive is made of a linear saturated polyester resin.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a bulletproof vest according to the present invention will be described below with reference to the drawings. FIG. 1 is a front view showing an example of a bulletproof vest according to the present invention, and FIG. 2 is a partial sectional view thereof. As shown in FIGS. 1 and 2, the bulletproof vest 1 is composed of a large number of high-strength fibers 2, 2,. It is composed of a bulletproof vest body 3 integrated with an adhesive and a cover 5 covering the bulletproof vest body 3.

The high-strength fibers 2 include para-aramid fibers, meta-aramid fibers, polyacrylonitrile-based carbon fibers, pitch-based carbon fibers, ultra-high-strength polyethylene fibers, polyarylate fibers, and ultra-high-strength polyvinyl alcohol fibers. Etc. can be used. For example, para-aramid fibers include Kepler.

As the synthetic resin adhesive, there is a linear saturated polyester resin or the like. The linear saturated polyester resin is a plastic material such as polyester, polyvinyl chloride, polycarbonate, ABS resin, aluminum, iron, or the like.
Has excellent adhesiveness to metal materials such as copper and various fiber materials such as polyester resin, and also has excellent heat resistance, flexibility and weather resistance. I do.

Since the bulletproof vest according to the present invention has the above-described structure, the bullets fired from the firearm cover the cover 5.
Penetrates into the bulletproof vest body 3, and a large number of high-strength fibers 2, 2,.
When the sheet advances while twisting one by one, the rotation of the bullet is braked by a large number of high-strength fibers 2, 2,. The rotation of the bullet is strongly damped, penetrating energy and collision energy are absorbed, the bullet can be stopped, and the bullet can be reliably prevented from penetrating.

At this time, the high-strength fiber and the synthetic resin adhesive become hot due to the heat generated at the time of impact of the bullet, but the linear saturated polyester resin as the synthetic resin adhesive has excellent heat resistance. It does not dissolve due to heat and can strongly stick bullets. In particular, no matter how strong the high-strength fiber is, when the bullet is shot, it opens in the direction of the woven fiber due to the characteristics of the fiber itself, so there is a weak point that the force to stop the bullet and repel is weak, but it is synthesized into a large number of high-strength fibers respectively. By being impregnated with a resin adhesive and integrated, it can be prevented from opening in the direction of the woven fiber, and the force for stopping the bullet and repelling it can be dramatically increased.

As a bulletproof vest test, a bulletproof vest (test sample A) formed from 36 Kepler impregnated with a synthetic resin adhesive, 30 ultra-high strength polyethylene fibers impregnated with a synthetic resin adhesive, and a bullet were tested. A bulletproof vest (test sample B) formed from several reinforced resin plates such as polycarbonate and acrylic for changing the direction of straight movement, and one duralumin chip and 30 ultra-high-strength polyethylene fibers impregnated with a synthetic resin adhesive. Made a bulletproof vest (test sample C) and a bulletproof vest (test sample D) formed from 40 ultra-high-strength polyethylene fibers impregnated with a synthetic resin adhesive. The latest high-performance pistols fired six bullets each. Test specimens A, B, C, and D all had six bullets. For not protrude from the rear surface of the body armor body, i.e. that the penetration was blocked it was confirmed.

Therefore, by impregnating a large number of high-strength fibers 2, 2, ... with a synthetic resin adhesive and integrating them, the adhesive strength is increased, and the strength and bulletproof performance are dramatically improved. Even bullets fired from powerful weapons such as magnums can be reliably prevented from penetrating. Further, since the strength and the bulletproof performance are remarkably improved, the number of high-strength fibers can be reduced, and the weight and cost can be reduced accordingly. In addition, since a large number of high-strength fibers are impregnated with a synthetic resin adhesive and integrated, it does not tear in the direction of the woven fibers, and can completely protect against piercing and hitting by an ice pick or a blade. Further, the use of a material that is resistant to weather resistance and aging can greatly improve durability.

In the above-described embodiment, Kepler and ultra-high-strength polyethylene fiber are used as specific examples of the high-strength fiber. However, the present invention is not limited to this, and other high-strength fibers may be used. . In the above-described embodiment, the linear saturated polyester resin is used as the synthetic resin adhesive. However, the present invention is not limited to this, and it goes without saying that another synthetic resin adhesive may be used. Further, in the above-described embodiment, 30, 36, and 40 high-strength fibers are laminated, but the present invention is not limited to this, and it is a matter of course that another number may be used.

[0015]

As described above, according to the present invention,
A large number of high-strength fibers are impregnated with synthetic resin adhesive and integrated to increase the adhesive strength, dramatically improving strength and bulletproof performance, and fired from powerful firearms such as Tokarev and Magnum. Even bullets can be reliably prevented from penetrating. In addition, since a number of high-strength fibers are impregnated with a synthetic resin adhesive and integrated, the strength and ballistic performance are dramatically improved, so it is possible to reduce the number of high-strength fibers. Cost can be reduced.

Also, since a large number of high-strength fibers are impregnated with a synthetic resin adhesive and integrated, it does not tear in the direction of the woven fiber, and can completely protect against piercing and hitting by an ice pick or a blade. It is possible. In addition, since a linear saturated polyester resin is used as the synthetic resin adhesive, it has excellent heat resistance and weather resistance, does not change with time, and can greatly improve durability.
