Definitions

  • the invention relates to armor according to the preamble of claim 1.
  • the object of the present invention is therefore to improve the protective effect of the armor of the type mentioned at the outset without having to accept higher grammages and greater structural depths.
  • the measures taken according to the invention can be easily implemented. If this happens, the result is a light and compact armor of versatile use. Their particular suitability for a wide range of uses can be explained by their high protection value against such diverse loads as bombardment with hard core ammunition, blast pressure and the impact of explosive-shaped projectiles on the one hand, and from a drastically reduced secondary splinter formation on the other hand, without this having a basis weight of more than 85 kg / m2 and a depth of more than 75 mm.
  • the share of metal layers in the total mass of the respective armor element as well as the thickness ratio between the fiber composite layers of the first and second armor element are of significant importance.
  • the metal layer of the first armor element preferably one made of high-hard armor steel, a mass fraction of 65% to 75% is recommended in order to counteract bombardment with hard-core ammunition extremely effectively in interaction with the upstream air gap. Where the latter applies, the risk of injury from secondary splinters, such as arise from the metal layer of the first armor element in the event of shaped charge or flat charge, can be eliminated or at least drastically reduced.
  • a mass fraction of 25% to 35% for the metal layer of the second armor element, preferably that of less hard armor steel, in connection with the upstream air gap has proven to be very effective, especially if a layer thickness ratio of 0.4 up to 0.6 to 1.0 to 1.3 between the fiber composite part of the first armor element and the fiber composite part of the second armor element is realized. This means that there are no noticeable bulges or dents on the back of the second armor element, as shelling tests have shown.
  • the single figure shows, in the form of a schematic diagram, an outer skin section of an object to be protected, for example a body panel part 1 of a passenger car.
  • an armor element 3 is arranged in an air gap 2 from the inside of the sheet.
  • It is composed of a metal layer 4 facing the sheet metal part 1 and a form-fitting fiber composite layer 5.
  • the metal layer 4 those made of 8 mm armor steel with a Rockwell C hardness of around 61.
  • the fiber composite layer 5 assigned to this consists, for. B. made of polyethylene pressed high-performance fibers. Their layer thickness is chosen so that the metal layer 4 accounts for 65% to 75% of the total mass of the armor element 3.
  • the fiber composite layer 9 exceeds the fiber composite layer designated 5 in a way that the mass fraction of the layer 8 in the armoring element 7 is 25% to 35% remains limited and the layer thickness ratio of fiber composite layer 5 to fiber composite layer 9 is in the range from 0.4 to 0.6 to 1.0 to 1.3.
