And, as shown in Figure 4, when the completed composite glove is mounted on the outside of the vehicle, etc. to form a protective body, the extending direction of the pipe member 20 located on the outermost is perpendicular to the bottom surface To be mounted.

Iron plate (S) is mounted on the outside of the protective body formed of a composite glove.

First, when attacked by shells or the like from the outside, the iron plate (S) primarily protects the target. If the iron plate (S) is damaged and penetrated, the outer plate member 10 to protect the attacked body second.

The outer plate member 10 has a plurality of materials forming a layer, each layer is to effectively protect the action.

First, the carbon fiber layer 16 of the outer plate member 10 absorbs and disperses the impact.

Carbon fibers are excellent in heat resistance and impact resistance, are lighter than metals, and are excellent in elasticity and strength compared to metals. Therefore, the carbon fiber layer 16 forming the outermost side of the outer plate member 10 absorbs and disperses the impact generated from the external attack. In addition, it is possible to increase the mobility of the vehicle by reducing the volume and weight of the glove.

The mixed resin layer 14 provided inside the carbon fiber layer 16 absorbs and disperses the impact of the attacking shell, and imparts repulsive elasticity to the opposite side of the shell entry direction to weaken the force of the shell.

Thermosetting resin has the property that hardness increases when heat is applied, and thermoplastic resin melts when heat is applied and the hardness decreases. When the thermosetting resin and the thermoplastic resin are mixed, there is an effect of stretching while maintaining a certain strength or more. Accordingly, the mixed resin layer 14 absorbs and disperses the impact generated from the external attack, and imparts repulsive elasticity to the opposite side of the shell entry direction to weaken the force of the shell.

The ceramic fiber layer 12 provided inside the mixed resin layer 14 lowers the heat of the attack shell and the temperature of the flame. The ceramic forming the ceramic fiber layer 12 is excellent in heat resistance and thus effectively withstands heat and flame of the shell.

In the mixed resin layer 14 provided inside the mixed resin layer 14, the mixed resin layer 14 once again absorbs and disperses the impact generated from the external attack, and repels the opposite side to the shell entry direction. Apply elasticity to weaken the force of the shell.

The carbon fiber layer 16 provided inside the mixed resin layer 14 absorbs and disperses the impact remaining through the mixed resin layer 14, the ceramic layer, and the mixed resin layer 14. , Lowers the remaining heat and flame temperature.

The pipe member 20, which is provided inside the outer plate member 10, is formed in a cylindrical shape and has a resilient elastic force to the outside. Therefore, the shock caused by the attack is absorbed and dispersed, and the repulsive elasticity is applied to the opposite side of the shell entry direction, thereby weakening the force of the shell.

The impregnated carbon fibers are formed by impregnating carbon fibers with a resin such as an epoxy resin for a certain time, and are superior in strength and rigidity to carbon fibers not impregnated, but have low elasticity.

Therefore, since the first carbon fiber layer 22 made of impregnated carbon fibers and the second carbon fiber layer 24 made of unimpregnated carbon fibers have strength and elasticity, respectively, they effectively defend, absorb, and disperse shock caused by attack. .

In addition, each layer of the pipe member 20 constituting a plurality of layered structures may be provided to cross vertically to more effectively provide a resilient elastic force.

In addition, the mixed resin member 40 provided in the space between the outer plate member 10 and the inner plate member 30 and the pipe member 20 absorbs and disperses the impact generated from the external attack and enters the shell. Repulsion is applied to the opposite side of the direction, weakening the force of the shell.

In addition, the mixed resin member 40, by increasing the density inside the composite gloves, to prevent the phenomenon of cracking due to the empty space.

The outer plate member 10, the inner plate member 30, and the pipe member 20 form a plurality of layered structures to increase the protective force.

The composite glove according to the present invention having the above-described structure effectively protects the impact of the attacking body and has the effect of suppressing the heat of the attacking body.
