Description

Lightweight Armor

The present invention relates to a light weight glove material, and more particularly to a lightweight glove material for protecting a fixed or moving object against attack, in particular, a hollow charge, an explosive-forming carbon or a projectile-forming carbon and a kinetic energy gun.

In general, the glove material protects the crew and important electric components inside the vehicle by preventing the bullet from penetrating when the bullet fired from the firearm is piled on the ship, submarine, aircraft, or combat vehicle.

In particular, combat vehicles are often operated in areas where there is a tactical threat to enemy firearms. In addition to kinetic energy, various types of risk factors, such as chemical energy guns and shell fragments, such as HEAT (High Explosive Anti-Tank), threaten the survivability of combatants. Combat vehicle gloves are developed considering these threats come.

The early gloves were made mainly of metal as a single material. Metal gloves are mainly made of Rolled Homogeneous Armor (RHA) steel, which is made of homogeneous iron. However, it is difficult to use glove material such as Faced-Hardened Steel Armor or non-ferrous material aluminum or titanium alloy, Has been developed and used. This single glove is also used as an inclination technique to reduce the projectile effect by using the inclination of the warhead and the glove material. This is a method of minimizing the penetration effect by inducing a wide contact area and inclined contact.

It is a form of gloves called as a space glove. It is a form in which another glove is attached to the outside of the body with a gap. In case of kinetic energy, the impact of the outer glove and the warhead on the body is minimized In case of HEAT shot, the center of injection force is dispersed in the space between the gloves, so that the penetration effect can be minimized.

A composite glove is a laminated glove with a special material arranged in the space of a glove, or a combination of a plurality of gloves.

The additional glove is a glove to be attached to the main glove forming the body, and is typically a reaction glove. Reaction gloves are a type of gloves that attach the ammunition filler to the box in addition to the main glove to disturb the focus of the HEAT shot by changing the direction of the shot in response to the explosive force of the shot.

Existing glove materials have been developed and applied mainly in developed countries mainly in the US, but they have not been able to effectively cope with all the threats because they have been practically used as a single material center. In the case of a single metal glove material, there is only a way to increase the thickness in order to increase the protection. However, the increase in thickness causes the weight to increase, which causes a drastic decrease in the attack power such as the deterioration of the starting performance and the fuel consumption.

Recently, a ceramic composite glove has been developed in order to ensure excellent protection and light weight. An example of such a ceramic composite glove is shown in FIG. As shown in FIG. 1, the ceramic composite glove has been developed on the basis of a two-layer structure in which a ceramic armor plate 10 is disposed on an upper surface of the ceramic glove and a metal glove 20 is provided on a lower surface thereof.

Such a ceramic composite glove is excellent in heat resistance, but after the damage is caused by a shell or the like, the cracks of the damaged region are enlarged due to the continuous impact, which causes a problem that the protective power is reduced rapidly.

Also, when the thickness is increased to increase the protection, the increase in thickness immediately causes an increase in the weight, which is an important factor for drastically lowering the attack power as well as the protection ability in case of emergency such as deterioration of maneuverability and fuel consumption.

It should be understood that the foregoing description of the background art is merely for the purpose of promoting an understanding of the background of the present invention and is not to be construed as adhering to the prior art already known to those skilled in the art.

Hereinafter, a lightweight armor according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

2 is a perspective view of a lightweight glove material according to an embodiment of the present invention. 3 is a cross-sectional view of a lightweight glove material according to an embodiment of the present invention. 4 is an enlarged view of part A of a lightweight glove material according to an embodiment of the present invention. 2 to 4, a lightweight glove box 100 according to an embodiment of the present invention includes a ballistic layer 110, a polymer composite material layer 120, and a bonding layer 130, So that the angle of incidence of the ballistics body that is traveling toward the center of the ball is not perpendicular.

Ceramic materials can provide effective protection against kinetic energy carbons as well as chemical energy carbons such as HEAT carbons due to their high hardness and rigidity, compressive strength and excellent heat absorption. The bullet-proof layer 110 is alumina (Al 2 O 3), silicon carbide (SiC), silicon nitrite (Si 3 N 4), boron carbide (B 4 C), aluminum nitride (AlN), titanium boride ( TiB 2 ) or a carbon (C) layer. Since each of the ceramic materials is different in specific gravity, area density, elastic modulus, hardness, etc., it is preferable to appropriately select and use it according to the risk factors of the glove material.

When the ballistic layer 110 is formed of a carbon (C) / silicon carbide (SiC) composite material, the heat resistance temperature can be largely increased through coating and densification to suppress matrix cracking due to oxygen penetration.

The polymer composite material layer 120 is formed on the top and bottom surfaces of the ballistic layer 110 to complement the ballistic layer 110 via the bonding layer 130. The polymer composite material layer 120 may be formed by coalescing fibers in a thermosetting resin and curing the fibers or by compounding the fibers in a thermoplastic resin. The thermosetting resin may be an epoxy resin or a phenol resin. The thermoplastic resin may be polyethylene (PE), polypropylene (PP), thermoplastic polyurethane (TPU), polyethylene terephthalate (PET), polybutylene terephthalate (PBT), nylon or the like.

 The fibers may include at least one of glass fiber, carbon fiber, aramid fiber, Kevlar fiber, ultrahigh molecular weight resin fiber.

The polymer composite material layer 120 serves as a reinforcing material on the front and rear surfaces of the ballistic layer 110. When used on the top surface, it exhibits good rigidity after impact impact with reduced projectile speed. In addition, when a material having a high density is used, the impact speed can be reduced and the economical efficiency can be achieved. It is also possible to use not only single fibers but also two kinds of fibers such as glass fibers and carbon fibers in a hybrid manner. When it is used for a bottom surface, it is intended to prevent the diffusion of the impact pressure generated from the ceramic, so that it acts as a buffer and prevents the debris from being injected into the inside.

The bonding layer 130 may be formed using a high-strength film-type adhesive or an epoxy-type industrial adhesive. In this case, when the polymer composite material layer is formed into an integral process, it shows high bulletproof efficiency. That is, when the epoxy-based material such as the polymer material used in the thermally polymerizable composite material layer is used, the bulletproofing efficiency can be improved.

In addition, a metal glove material may be additionally used in addition to the polymer composite material layer. Such a metal glove material includes a steel glove material and an aluminum alloy. Rolled Homogenous Armor (RHA), Faced-Hardened Steel Armor and the like may be used as the material of the steel glove, and aluminum alloy may be used particularly when weight reduction is required. Further, a filler such as rubber, polyurethane, acrylic resin, etc. for preventing the diffusion of the impact pressure can be used. In addition, a composite material having excellent flame retardancy can be disposed on the lower surface of the glove to prevent the spread of fire due to chemical energy The electromagnetic wave shielding structure material may be disposed on the upper surface or the lower surface to avoid interference by electromagnetic waves.

It is preferable that such a lightweight glove material be formed with an inclined surface such that the incidence angle of the ballistic element is not vertical. As shown in Figs. 2 to 4, these inclined surfaces can form inclined surfaces by protrusions formed in the form of polygonal horns. In Figs. 2 and 3, the shape of the projection is a tetrahedron, but the shape is not limited thereto. By this inclined surface, it is possible to minimize the penetration effect by inducing the wide contact area and the inclined contact of the ballistic body. Particularly, when the protrusion is formed in the form of a polygonal horn, the surface on which the oblique contact is not made can be minimized.

5 is a schematic view of a lightweight armor according to an embodiment of the present invention. Basically, the lightweight glove according to one embodiment of the present invention can be installed so that the direction of the ballistic body is directed to the edge of the tetrahedron.

The movement of the lightweight glove material according to an embodiment of the present invention is accompanied by simultaneous hydrodynamic flow and dynamic repulsion. The polymer composite material layer on the upper surface primarily attenuates the impact energy and suppresses the occurrence of the crushing phenomenon on the upper surface of the ballast layer while the ceramic particles generated by colliding with the ceramic material or the carbon layer are ejected to the collision upper surface Minimize the role.

The ballistic material passing through the polymer composite material layer on the upper surface is ruptured due to a strong compressive stress while flowing into the ballistic layer 110, and at the same time, the ballistic layer 110 is provided with a conical Hertzian cone crack So that the lower surface rupture is caused by the tensile stress applied to the lower surface thereof, and the rupture and flow of the ball is continued. Through this process, the destruction of the ballistic body and the fracture of the ceramic are propagated to the entire glove material.

The polymer composite material layer on the lower surface serves to prevent the destruction of the ballast layer 110 by preventing conical fracture of the ballast layer 110 in the course of destroying the ballast layer 110. Then, 110 are broken and are bent by the pressure generated while flowing. At this time, the tensile and shear stress acts on the underneath polymer composite layer. The fiber material and the thermosetting polymer material have a resistance to shear and tensile, and they can absorb the energy while bending to some extent.

The lightweight glove material according to the present invention as shown in FIG. 6 can be implemented not only as a glove material for a combat amount itself, but also as a glove made of a conventional glove layer 400. At this time, the glove layer 400 and the light weight glove material 100 according to the present invention may be connected by the connection rod 150 to be spaced apart from each other. The gap between the lightweight glove material 100 formed on the outside and the ballistic body, the impact of the ballistic element, and the effect of the debris and the carbon core on the body can be minimized to obtain a debris damping effect. In the case of the HEAT plate, So that the penetration effect can be minimized.

Further, as shown in Fig. 7, the shape of the protrusion may be formed in a hemispherical shape. When the protrusion is formed in a hemispherical shape, it is possible to prevent breakage of the end portion rather than a polygonal pyramid shape.
