Definitions

  • the invention relates to a multilayer armor protection material, which consists of a one-piece or multi-piece ceramic or metallic front layer and one of these downstream hard support layer is formed.
  • DE 41 14 809 Al is already a bullet-proof plate material known in which a multi-piece ceramic or metallic front layer with a multi-layer laminate connected by a layer of an elastic binder is.
  • the first layer of laminate is a hard, the front layer is not supportive and essentially elastic deformable layer with a subsequent second, flexible and elastically deformable laminate layer as so-called Trapping layer with a thin rubber or acrylic adhesive film connected with a uniform thickness of about 0.2 to 0.4 millimeters is.
  • the first layer of laminate is made of a hard, highly compressed GRP material formed while the flexible Laminate layers of the second or subsequent trapping layers become soft GRP materials or aramid fabric.
  • Such a known plate material offers with respect to one Multi-hit behavior the advantages described. It can be Hard core bullets up to caliber 7.62 millimeters with inexpensive Weight advantages compared to armored steel sheet and comparable Stop multi-hit properties.
  • the special materials used such as ceramics, GRP and aramid are significantly less expensive than an armored steel sheet are.
  • the caliber of a projectile is increased for example .50 (12.7 millimeters) or 14.5 Millimeters is still a good function of the known one Given plate material, however, the costs then move at a very high level.
  • Vehicle structures are also mostly in the caliber range mentioned made of armored steel or aluminum with a certain Basic protection, for example against soft or hard core bullets available in caliber 7.62 millimeters, on which an additional armor adapted to achieve the required overall protection becomes.
  • Such a vehicle structure in the formation of a vehicle trough plate or tower housing thus takes over the function the trapping layer analogous to DE 41 14 809 A1.
  • a bullet-proof Plate according to this document should therefore equally good results without the second or subsequent catch layer can be achieved if the front layer is made of multi-piece ceramic in conjunction with a flexurally hard GRP laminate layer as a protective plate on the steel sheet or aluminum housing would be attached directly.
  • a multilayer arrangement of thick plywood and thin Stainless steel combined with nylon or polyester mesh is in GB-A-2 191 147 as a protective arrangement (total thickness 160 mm) from Buildings.
  • US-A-4 567 100 discloses a ballistic resistant Layer structure with an outer thin steel plate and a massive thick hardwood layer arranged behind it. Only this hardwood layer is followed by the ballistically effective one Layering made of polycarbonate (PC) and thin armor steel. The Finally, a thin sheet of steel is used as cladding. The wood is in this arrangement before the ballistic one Layer arranged and contributes to ballistic resistance when at all, only very subordinate to. The wood with a thickness of approx. 38 mm in connection with the outer skin alone the function of the mechanical and thermal resistance against Burglary tools (cutting, welding).
  • BE-A-0 504 020 is an armor plate against projectiles described, which made of wood fibers or layered wood foils (Veneers) is formed.
  • the wood fibers or alternatively the Veneers are made using formaldehyde (chipboard) or Phenolic resin to a plate with a density between 1.2 and 1.4 g / ccm compressed.
  • this wooden panel can at least have a metallic reinforcement.
  • US-A-4 404 889 is a mixed multilayer structure for mine protection of armored vehicles (vehicle floor).
  • vehicle floor inner wall closes an approx. 13 mn thick layer of balsa wood (12) followed by a very thin steel foil (14), a Kevlar layer (16) from 13 to 19 mm, another thin steel foil (18), a honeycomb structure (20) made of steel and one outer steel plate (22).
  • the attacking side is therefore the one outer steel plate (20).
  • the honeycomb, kevlar and balsa wood sandwich bottom the absorption of the blast effect from the explosive through plastic Deformation takes over.
  • the synthetic resin pressed wood used consists of beech wood veneers, which are bonded with hardenable synthetic resins under pressure and heat are.
  • the synthetic resin pressed wood has a density between 1.3 and 1.4 g / ccm.
  • the water absorption is equal to or less than 0.5% very low, which is why this material does not swell either.
  • the LIG plate made of cross-layered, high-density resin molded wood practically does not delaminate in the impact zone more because it has very hard, brittle properties and therefore with the high dynamic loads because of their very hard structure and because of the impregnation with resin only in direct impact area breaks. Already immediately around the zone destroyed by bombardment, the material remains completely intact and has no signs of delamination.
  • the Thickness of the LIG plate compared to a weight-equal hard GRP plate can be increased accordingly, thereby reducing the Flexural rigidity of the support layer is generally increased.
  • the Performance of the ceramic compared to the armor-piercing Ammunition can be greatly improved.
  • the thickness of the ceramic tiles could in relation to a comparable ceramic-GRP composite can be reduced without loss of performance or it increased clearly the limit speed v50 with the same thickness. Further
  • the dimensions of the ceramic tiles can be another advantage compared to the bulletproof plate material DE 41 14 809 A1 can be enlarged without any loss comes in the multi-hit ability.
  • a LIG plate in the arrangement and construction according to the invention costs compared to a comparable hard GRP support layer, based on an equal weight, only about 30% of the price of one GRP panel.
  • a number of ceramic composite panels were used with the material according to the invention for a wide range of protection classes manufactured and tested with a variety of protective structures.
  • Adhesives including with adhesive films according to DE 41 14 809 A1, connected to the LIG plate.
  • the performance of a composite material of the invention Design relatively small due to changes (material, Adhesive thickness) affected by the different adhesives becomes.
  • the support layer according to the invention can not only be use as a support plate for a ceramic layer in the composite, but it is also very effective as a backing layer a thin, hard hard steel sheet or as Layer material between two armored steel sheets.
  • the LIG plate is a thin layer of plastic or metal to stabilize the rear side of the resin molded wood is attached, so as to flake off the brittle Avoid wood-based materials.
  • This measure is special advantageous if too with high shock or impact loads is to calculate how it is, for example, with soft core ammunition or with norm splinters.
  • a catch layer made of plastic or metal materials is arranged be so that a composite panel of this type as a single element can be used in armor protection.
  • FIG. 1 shows a multi-layer Armor protection material 13 with a front layer 1 made of metal or ceramics.
  • a front layer 1 made of metal or ceramics.
  • an adhesive layer or Adhesive film 5 is on the rear side of the front layer 1 the support layer 2 made of a synthetic resin pressed wood (so-called LIG plate) attached.
  • the support layer 2 synthetic resin is made of cross-layered beech wood veneers formed, highly compressed and additionally impregnated with phenolic resin in a vacuum process.
  • On the side opposite the support layer 2 is on the Front layer 1 in turn with the interposition of an adhesive layer or adhesive film 4 a cover layer 3 attached. This top layer 3 is the landing approaching in the direction of arrow 14 facing.
  • the front layer 1 has a thickness in the example shown between six and eight millimeters, while the support layer 2 is about six millimeters thick.
  • the front cover layer 3 has a thickness of about one to two millimeters.
  • the adhesive layers 4 and 5 are about 0.3 millimeters thick.
  • the front layer 1 For example made of ceramic exists, impinging projectile (hard core projectile) penetrates the top layer 3 and also the front layer 1, the hard support layer 2 (LIG plate) does not bend. That means, that the projectile also penetrate this support layer 2 got to.
  • the hard-supported front layer 1 takes place next to one first effective energy destruction of the projectile breaking the hard core or at least removing the Bullet tip. Since the support layer 2 only in the direct impact area is penetrated and no longer tears or splinters or peels off, the front layer 1 is also advantageous supported. This will make larger bullet craters or more adjacent bullet craters avoided, so that subsequent Splinters or blasted pieces of the armor cannot penetrate.
  • the multi-layer armor protection material 13 through a stabilizing layer 7 behind the support layer 2 added.
  • the stabilization layer 7 is again by means of an adhesive layer 6 with the support layer 2 connected and serves the purpose of chipping off the brittle wood material largely avoided.
  • the stabilization layer 7 consists of a plastic or metal. With this simple Additional measure makes the support layer 2 effectively straight when shelling soft-core ammunition or when hitting it supported by standard splinters.
  • the multilayered armor protection material according to FIG. 3 is opposite the structure according to FIG. 1 supplemented by a catch layer 8, which with the interposition of an adhesive layer 6 with the back the support layer 2 is firmly connected.
  • This trap layer 8 is made either made of plastic or metal and is basically softer than the very hard support layer 2.
  • an impact of a hard core bullet on the armor protection material 13 from the direction of the arrow 14 becomes the front layer 1 and also penetrated the support layer 2.
  • the downstream Catch layer 8 the already braked floor is caught. This collection is due to partial deformation the catch layer 8 visible.
  • FIG. 5 shows a further combination of a structure of the multilayer Armor protection material 13.
  • a further armored steel plate 10 On the back of the Composite of front layer 1 (9) and support layer 2 according to the figure 5 is a further armored steel plate 10 by means of the adhesive layer 6 attached.
  • the two armored steel plates 9 and 10 can be of the same or different thickness be what arises from the expected circumstances / threats for the specialist.
  • FIG. 6 again discloses the use of a stabilization layer 7 behind the support layer 2 in the case of a front layer 1 from steel sheet 9.
  • FIG. 7 A special application of a multi-layer armor protection material 13 reveals Figure 7.
  • the armor protection material 13 has here the structure of Figure 1 with the top layer 3, the front layer 1 made of ceramic tiles 15 and the support layer 2 Resin pressed wood. Between the individual layers of the network are adhesive films or adhesive layers 4 and 5, respectively used.
