Description

[0016] The invention is described below based on an embodiment which is shown in the enclosed drawings. They show:

[0017] FIG. 1 a perspective, schematic view of an armor plate; and

[0018] FIG. 2 a cross-section of an armor with a carrier onto which several armor plates are glued by means of an adhesive layer.

[0019] FIG. 1 schematically shows an armor plate 10 which is rectangular in the exemplary embodiment shown and has a constant thickness d.

[0020] The thickness d is several millimeters and depends on the desired protection class. For protection at the level STANAG 4, the thickness is in the order of magnitude of 5 to 10 mm.

[0021] In any case, the thickness of the armor plate 10 is selected in such a way that the plate as such is inherently stable.

[0022] The dimensions of the armor plate 10 are comparatively low. For rectangular plates, the edge lengths a, b are in the order of magnitude of at least 20 mm and preferably in the order of magnitude of 40 to 60 mm.

[0023] The armor plate 10 is a massive component made of tungsten heavy metal or tungsten carbide. The usual sintering methods, which are generally known for these materials, can be used for manufacturing.

[0024] In deviation from the rectangular shape, any shape which is suitable for completely covering (apart from the joints between adjacent armor plates) a subjacent surface area with several armor plates arranged next to each other may be used in principle. For example, the armor plates may also have the shape of an equilateral hexagon.

[0025] The joints between adjacent armor plates should be at least 0.55 mm and preferably at least 1 mm but preferably no more than 1.5 mm.

[0026] FIG. 2 shows the structure of an armor containing several of the armor plates 10 shown in FIG. 1.

[0027] The armor shown in FIG. 2 uses a carrier 12 onto which the armor plates 10 are glued adjacently to each other.

[0028] The carrier 12 consists of a steel alloy, in particular a high-strength steel alloy, as is used in the field of vehicle armor.

[0029] The armor plates 10 are glued onto the carrier 12 by means of an adhesive layer 14. The adhesive forming the adhesive layer 14 is a silicone-based adhesive.

[0030] In principle, it is conceivable to use an adhesive layer with a constant thickness. However, as seen in FIG. 2, the adhesive layer has a generally wave-shaped profile when viewed in a cross-section. As a result, the armor plates 10 are in contact only with the (flattened) wave crests of the adhesive layer 14. Channels 16 are formed between the individual wave crests and are each filled with air.

[0031] The special advantage of the armor shown in FIG. 2 is that the individual armor plates 10 can be exchanged separately, if necessary. The adhesive layer 14 ensures mechanical damping between the armor plates 10 and the underlying carrier, which increases the protective effect.
