The rupture disks of reactive armor that may be provided are initiated or light armor is destroyed directly when bomblets with frontal hollow charges are dropped onto vehicles. Previously known disrupting elements that prevent a shaped-charge jet from forming are mostly composed of pointed parts protruding from the surface of the vehicle or layers which are covered by a sensitive film. The disadvantages associated with said disrupting elements can be overcome in an economic manner by using a single protective layer (1) which consists of a high-density elastomer, is placed as a protective roof cover in the vertical projection of a vehicle (100), and can be retrofitted onto existing vehicles and installations. Also disclosed is a method for producing protective layers (1), which is based on the use of a PUR high pressure system and previously known high-density starting materials.

Selon l'invention, le largage de bombettes à charges creuses frontales sur des véhicules entraîne le déclenchement des diaphragmes d'éclatement de blindages réactifs éventuellement présents ou détruit directement des blindages légers. Les corps perturbateurs connus qui empêchent la formation d'un jet de charge creuse sont principalement constitués de parties pointues qui font saillie par rapport à la surface du véhicule, ou d'une couche qui est recouverte par une feuille sensible. Les inconvénients associés auxdits corps perturbateurs peuvent être supprimés de manière peu onéreuse au moyen d'une couche de protection unique (1) constituée d'un élastomère de densité élevée, qui est placée dans la projection perpendiculaire d'un véhicule (100) en tant que protection de toit, et qui peut être utilisée sur des véhicules et des installation existant(e)s. Cette invention concerne en outre un procédé de production de couches de protection (1), fondé sur l'utilisation d'une installation haute pression PUR et de matériaux de départ de densité élevée connus en soi.
