Lightly armoured vehicles and stationary objects are often the target of attacks by means of hollow-charge projectiles. Numerous variants of armour plating have been developed to counter such attacks, which results in additional loads, and these require expensive production. A light protective layer (1) which is simple to produce contains rods (3) arranged in a matrix, which project out from the object to be protected. If a corresponding hollow-charge projectile hits such a protective layer (1), the front nose (101) thereof is damaged, so that in most cases the initiation of the hollow charge does not occur. Preferably the rods (3) are covered externally by polymer layers (9, 10) and additionally a crumple layer (8) is attached in front of the object to be protected.
A protective layer for protection of an object against an active projectile having a tip and a selected calibre, the protective layer comprising metallic rods arranged in a matrix and projecting from the object to be protected, each rod having an end region remote from the object to be protected with a galvanically conductive surface, wherein the rods project beyond an upper inner surface of the protective layer, and wherein a diagonal distance between the rods is less than the calibre of the projectile and greater than the tip of the projectile.
A method for producing a protective layer with rods arranged in a matrix and projecting from a surface for protection of an object against at least one of an unguided medium-calibre projectile and a subsonic medium-calibre projectile with an electric impact fuse, comprising providing a metal strip and cutting out surfaces with a U-shaped contour from the metal strip at equal distances such that rods with a web remain.
