Description

≪ Desc / Clms Page number 1 > Bulletproof protective panel <

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a protective panel for an armor, and more particularly to a protective panel for minimizing an impact generated by projectiles.

A protective panel for a bulletproof or inspectable body intended to protect "protected body" such as a hull, a body, and a human body against an attack by a weapon having a sharp end, such as a warhead or a sharp end such as a knife, "Or" protective structures "are widely known.

Such a protective panel or protective structure is provided in the form of a bulletproof or bulletproof armor to be worn by a person, a vehicle or armor plate for reinforcing the outer wall of a car or civil vehicle, a ship or the like by using an iron plate, Or it is detachably attached according to the needs of the object to be protected, thereby providing a bulletproof and sanitary performance.

On the other hand, the protection panel or the protection structure is manufactured by molding the projected shell into a shape of a member to be protected such as a human body or a hull so as to have durability against the launched shell.

Further, by attaching a plurality of protective panels of the single piece to the base fabric of the bodyshell in the form of scales, the amount of impact from the bullet is absorbed and dispersed by using a plurality of protective panels so that the amount of impact generated upon collision with the bullet is not transmitted to the rear There is a plan to do it.

However, the present laminated structure of the protective panel has a problem that its thickness and weight increase in proportion to the increase in the bulletproof performance, as the research is focused on only the lamination in the thickness direction of the protective panel. Further, there has been a problem that the impact amount distribution through the laminated protective panel is not effectively performed.

In addition, when a protective panel or a protective structure is employed in a vehicle or a ship, the protective panel must be mounted integrally with the outer wall when assembling the first vehicle and drying the ship.

Furthermore, if the protective panel is damaged by the projectile, the entire protective panel must be replaced at present, which causes a problem of increased maintenance cost. Furthermore, in order to reduce the cost, there is a case in which a protective panel or a protective structure is used while leaving the damaged portion as it is, but in this case, when the bullet is re-piled, the protection function is not performed at all.

It is an object of the present invention to provide a protective panel for a bulletproof type employing an improved laminated structure to reduce the amount of the impact of the ceramic hard body generated by the projectile to the adjacent ceramic hard body.

The protective panel for a bulletproof according to an embodiment of the present invention includes a ceramic hard body layer having a plurality of ceramic hard bodies and a predetermined region of each of the ceramic hard bodies being arranged in a superimposed manner; An impact absorbing layer laminated on one surface of the ceramic hard body layer; And a polyethylene layer (PE) laminated on one side of the impact absorbing layer.

The ceramic hardness layer of the protective panel for a bulletproof panel according to an embodiment of the present invention is characterized in that the ceramic hardness layer is composed of a first ceramic hardness layer and a second ceramic hardness layer in which a plurality of the ceramic hardness elements are arranged in the transverse direction and the longitudinal direction, And the first ceramic hardness layer and the second ceramic hardness layer may be laminated while being offset from each other.

The ceramic hardness layer of the protective panel for a bulletproof according to an embodiment of the present invention may be formed by laminating the first ceramic hardness layer and the second ceramic hardness layer many times.

According to an embodiment of the present invention, at least one of the side surfaces of the ceramic hard body may be adjacent to at least two other ceramic hardened bodies.

According to the protective panel for a bulletproof according to the present invention, the amount of impact of the ceramic hard body generated by the projections can be reduced in a manner of transmitting to the adjacent ceramic hard bodies.

In addition, even when the impact of the projectile occurs on the boundary between the ceramic hardness elements, the impact can be effectively dispersed.

Further, when the protective panel is broken by the projectile, it is possible to easily replace the protective panel, thereby reducing the cost.
