DE2815582A1 - Laminated armour plate - with minute particles embedded in matrix at specified angles - Google Patents

Abstract

Laminated bullet-proof armour and glass for motor vehicles and protective vests consists of >=1 layer in which minute particles, pref. in the shape of spherical ring sectors, are embedded. They consist of oxide-ceramics, sinter metal, high-strength steel or similar materials and are arranged at an angle from 5 to 85 degrees to the surface. They are embedded in a matrix such as nylon, polyurethane or hard rubber. The angle of incidence between bullet and embedded particle ensures an optimum dissipation of the kinetic energy of the bullet.

Description

Multi-layer armor, in particular consisting of small bodies.

The invention relates to a further development of the patent application P 27 59 193.1 Requirement from the vehicle industry, as light as possible and in particular Producing thin-walled armor layers with optimal security required one further specially designed arrangement of the multilayer armor and the multilayer armor Bulletproof glass.

The invention seeks to remedy this need, which is why its task is based on creating armor that, through its composition of material, Component sizes and their arrangement.

According to the invention, the object is achieved in that the for use coming parts adjusted in their arrangement and angle setting to the surface are that the material composition of the components with the angle setting the result in optimal energy destruction.

The distance between the individual components in their angular setting is determined according to the intended scope of protection.

With a calculated and intended protection against projectiles with 5, ei5 mm the component distance from the component surface to the component surface is approx. 5 mm. Thus the energy of the bullet is not at the tip of the bullet but on one the large area corresponding to the size of the storey is absorbed.

In the case of armored glass, the space between the components must be covered with a corresponding Slide completely filled out.

With a multi-layer armor made of oxide ceramic, sintered metal, high quality Steel and other oxide ceramics, metal and or sintered metal combinations are depending on the use of synthetic resins and / or polyurethane, certain weight-saving Free spaces possible.

Fig. 1 shows in section the representation of a multi-layer armor. 2 in section the representation of a multilayer armor with differently arranged Components.

3 shows, in section, the representation of a multilayer bulletproof glass.

Fig. 4 shows in section the representation of a multilayer armor with outstanding components from the cast body.

5 shows a sectional representation of a multilayer bulletproof glass with another component arrangement.

Fig. 6 in section, the preferred shape of components for special Application.

It shows Figure 1 is a multi-layer armor that is in the 1st layer Components 21 shows, which are preferably made of oxide ceramics and / or sintered metal and in the body 22, preferably made of polyurethane, nylon and or similar synthetic resins are cast or vulcanized in hard rubber. The components 21 are preferably with about 450 arranged to the surface. This arrangement makes the incident Projectile deflected at each point of the component 21 so that a larger area of the projectile collides with the components and the energy absorption of the projectile is made possible.

Fig. 2 shows a preferably further arrangement of the components 21 cast or vulcanized into the receiving body 22.

Fig. 3 shows a multilayer armored glass, the 1st layer 23 of which is armored glass is in a known manner. The 2nd layer is covered by a film 24 in a known manner with components 23 together in a special design and arrangement made of bulletproof glass material educated. The third layer is formed by a film 24 in a known manner. In armored glass is placed on the 4th layer 23 in a known manner. From the 1st shift 23 up to and including the 4th layer 23 is the multilayer bulletproof glass in one solid armored glass body joined together.

4 shows a preferably further embodiment of the multilayer armor, where the body 22 is designed so that the components 21 with both inclined surfaces protrude from the body.

Fig. 5 shows a multilayer bulletproof glass that is in the 1st layer with a bulletproof glass is formed in a known manner. The 2nd layer is through a Foil 24 in a known manner with components 23 which are very large due to their arrangement Destroy energy, formed from bulletproof glass material, arranged.

The 3rd layer is formed by a film 24 in a known manner.

In the 4th layer, bulletproof glass is arranged in a known manner. All layers are joined together to form a solid armored glass body.

Fig. 6 shows a preferred embodiment of components for armored glass and or multilayer armor, the illustrated embodiment being only one embodiment represents. The radius is intended to be smaller in accordance with the safety requirements and or bigger.

The embodiments can of course go even further can be varied so that appropriate shapes are arranged for all requirements will.

The advantage of the inventive multilayer armor and the multilayer armored glass according to the invention is due to the arrangement of the components in given a certain angle to the surface of the body and in this assignment novel.

Due to their angular arrangement, the components offer the highest possible Safety to deflect the impacting projectile so that the projectile body with the greatest possible surface contact to the components 21/23 comes and through the occurring high friction the projectile energy is absorbed. When the Projectile at a 90 ° angle on the components, the projectile energy would be at least twice its length based on the thickness of the multilayer armor. The security for the endangered object is with this novel arrangement of Components optimally.

The weight and body thickness of the multilayer armor and the Multi-layer armored glass is so cheap that it can be installed in motor vehicles and other objects does not pose a problem.

Component arrangements are preferably shown in FIGS.

For the sake of clarity, no further component arrangements are shown, because the variety of possibilities is so great that the overview would be difficult.
