Definitions

  • the invention relates to a ballistic multilayer arrangement for the defense against projectiles or other highly accelerated parts.
  • Ballistic plates are used in all types of armor, be it on vehicles, airplanes, buildings or directly portable to persons.
  • the disadvantage is usually the very high weight of the plates must necessarily be thick enough to meet the bullet class.
  • a prior art ballistic plate 9 is shown, this has on the bombardment side a ceramic plate 91 with a projectile to be braked and at best partially disassembled followed by one or more layers of aramid fibers 92 finished with a steel plate 93rd
  • the object of the invention is to provide a ballistic multilayer arrangement which is reliable and saves material in the production.
  • a ballistic layer for a ballistic multilayer arrangement such that it is formed by an absorption layer which consists entirely or predominantly of expanded glass, wherein the expanded glass is in the form of sintered expanded glass granules which are in one dense packing or bed is held by a matrix surrounding the expanded glass granules.
  • Expanded glass is foamed glass with small, gas- or air-filled pores and can be produced in different grain sizes.
  • the granules are close to each other and are at least partially enclosed by the matrix.
  • the layer may be provided in the sense of the invention flexible as a mat or tarp or in particular with the further embodiments as a rigid plate.
  • the expanded glass granules have a granule size of 0.01 mm to 5 mm.
  • the expanded glass or expanded glass granules consist predominantly of SiO 2 . Further preferably contains as further ingredients Na 2 O and CaO and also preferably contains as further ingredients to a slight extent less than 10 weight percent Al 2 O 3 and / or MgO and / or K 2 O.
  • the matrix of the expanded glass granulate is formed according to a particularly advantageous embodiment of the invention of plastic or resin or a plastic / resin / mixture, which is particularly impact resistant. This allows a particularly good energy absorption from the projectile.
  • plastic mixture polyurethane and / or polyethylene and / or oxide resin and / or silicone and / or an impact-resistant plastic and / or an impact-resistant plastic.
  • a ballistic multilayer assembly having an impingement side and a backside, and a ballistic layer according to any one of claims 1 to 7, wherein at least one of the layers of the multilayer ballistic layer is constituted by a multi-layered layer of fibers Aramid fibers or comparable fibers is formed, wherein this is present in particular in a woven or multi-layer fabric form.
  • At least one of the layers is formed by a fine stone or natural stone or ceramic or ceramic mixing plate, in particular of a composite material.
  • a projectile can be braked very effectively by the necessary destructive force of the plate, be partially disassembled and brought out of the track, which increases the effectiveness in the following layers by a widened attack surface.
  • Light or low-energy projectiles can be completely stopped by such a layer.
  • a projectile can also be very effectively deflected when passing through the layers by a splinter layer provided with advantage according to a development of the invention.
  • the splinter layer is formed by ceramic or ceramic metal or porcelain or natural stone fragments bonded in a matrix.
  • at least one layer of the ballistic multilayer assembly is formed by a metal plate.
  • At least one layer may be formed by a high-plastic layer, this may preferably be formed by the high-plastic plastic layer of the matrix of the absorption layer.
  • the arrangement is surrounded by a plastic cover layer or fiber-reinforced plastic braid layer at least on one side of the Beauftschungs- and back.
  • a plastic cover layer or fiber-reinforced plastic braid layer at least on one side of the Beaufschlagungs- and back.
  • At least one fine-grained, natural-stone or ceramic layer, a fiber layer and a metal layer are advantageously provided in addition to the absorption plate.
  • Fig. 1 is a schematic representation of a ballistic multilayer assembly 1 according to the invention shown.
  • an absorption layer 2 is arranged.
  • Fig. 2 is an alternative Arrangement in opposite order of absorption layer 2 and fiber layer 4 shown.
  • the layers are interconnected in all examples either mechanically or with suitable adhesives.
  • the absorption layer 2 consists of expanded glass 21 in the form of expanded glass granules 22 which is held in a dense packing by means of a matrix 24 surrounding the expanded glass granules, see Fig. 3 ,
  • the matrix 24 is formed of an impact-resistant plastic mixture. Good results were made with impact-resistant polyurethane blends.
  • Blähglas 21 is very light, round and unbreakable grain-free, highly heat-insulating, sound-absorbing, pressure-stable, non-flammable, acid-resistant and pest-proof.
  • the granules 22 themselves may be closed or open-pored with a granule size of 0.01 mm to 5 mm.
  • the foamed expanded glass granules 22 have, as exemplarily in Fig. 4 shown in a cross-section, a bubble size 23 of 0.001 - 0.5 mm.
  • the layer thickness of the absorption layer can be 0.5 to 50 mm between layer thicknesses.
  • the fibrous layers 4 (41, 42, 43) in the examples are multi-layered multi-layer fabrics of aramid fibers. However, comparable fibers can also be used.
  • FIG. 6 An exemplary construction of a ballistic multilayer arrangement 1 as a plate with an absorption layer 2 is shown.
  • the layer sequence seen from the loading side A is as follows. Outside, first a plastic cover layer 8 is provided. This serves the conclusion against the outside and the protection that smashed parts of the following very hard first ceramic layer 5 after a hit by a projectile not fall out and the structure is held together even if cracks in the ceramic layer 5, if another hit in the environment of an impact occurs.
  • the ceramic layer 5 may in the context of the invention also of other materials, such as fine stone or natural stone or a
  • the "ceramic” layer 5 is hard. This can make classic ceramics but also substitutes such as very hard natural stones (granite etc.) or fine stone, a very hard high-fired earthenware.
  • the ceramic layer 5 On the ceramic layer 5 is followed by a fiber layer 4 of aramid fabric. This is followed by the absorption layer 2 which is able to absorb the energy of the projectile or splitter. In the absorption layer a lot of energy is absorbed by the projectile and distributed in the way on a much broader base, so that afterwards a metal plate 7 can be sufficient as a conclusion.
  • Fig. 7 Also possible is a variant in which a second 42 is provided in front of the steel plate 7 after a first fiber layer 41 just in front of it.
  • a first steel plate 71 is installed in the after the ceramic layer 5. This additionally stabilizes the ceramic layer in the immediate vicinity of an impact. This can be advantageous for multiple projectile entry.
  • a steel plate 72 is provided on the back B again. This can already be formed by a vehicle outer wall in light armor or by a normal outer wall.
  • a splinter layer 6 which contains bound in a matrix 62 ceramic or ceramic metal or fine stone or natural stone splitter 61. It depends less on the sequence of layers rather than on the presence of a fragmentation layer, which contains very hard a projectile or a hard bullet core (tungsten carbide, for example) distracting fragments bound in bulk in a matrix.
  • both absorption layers 2a and 2b are adjacent to another fiber layer 41 and 43 and subsequently provided with a steel plate 71 and 72.
  • the layers as in the examples shown above may also be made in a different order with partial omission or multiple ranking.
  • absorption layers according to the invention have excellent thermal insulation as a property.
  • vehicles as well as buildings or tents could be isolated against the outside world against heat or cold without requiring another layer or other measures.
  • the structure of the absorption layer according to the invention is sound-insulating. This property is also advantageous in the proposed application.
