Definitions

  • the invention relates to a tank device as characterized in the preamble of claim 1 and a method for their production.
  • a tank device of the type mentioned at the outset has become known (US Pat. No. 4,179,979), non-metallic balls being arranged in layers with layer material lying therebetween, the interstices being filled with a polyurethane foam.
  • This arrangement essentially only enables the production of plate-shaped protective elements, so that arrangements in any cavities between armored plates are not possible.
  • the manufacturing effort is very high because of the aligned arrangement of the balls.
  • DE-A-2 759 193 also shows a plate-shaped protective armor, in which layers of thick-walled hollow spheres made of e.g. B. also oxide ceramics are neatly embedded in nylon or synthetic resin.
  • This protective armor is primarily intended to protect against rifle projectiles on people and light vehicles.
  • protective armor for projectiles has become known (US-A-3 573 150 and EP-A-0 041 271), in which rows, preferably round rods made of glass or ceramic are embedded in an elastomer or a polymer plastic, only cuboid protection moduli can thus be created.
  • All armor devices of the type mentioned above have no or only insufficient protection against shaped charges.
  • the object of the present invention is to provide a tank device of the type mentioned at the outset which, by simple means, ensures a higher protective action against shaped charges, the security against multiple bombardment in particular being improved.
  • the armor device should have a low weight and be usable or producible in a wide variety of shapes.
  • the hollow spherical fillers preferably consist of corundum, which has great hardness with a low specific weight.
  • the combination of these hollow spheres with the polyurethane two-component plastic results in a low specific weight of the armor.
  • this combination enables the filling of cavities of various shapes, so that even inaccessible areas can be provided with protective armor.
  • solid cured blocks can be produced as moduli, which, for. B. arranged on armor plates form a combined protection.
  • cavities 2 are arranged in an armor plate 1 or an armor plate element - also called a module - evenly or unevenly distributed, which have at least one filling opening, but are preferably accessible from the outer surface.
  • Hollow-shaped fillers 3 are arranged in the cavities 2.
  • the cavities 2 can be arranged on the outside as well as on the inside of an armor plate or a plate element and covered with a plate.
  • the filler 3 are hollow spheres 13 or hollow spherical.
  • the filling of each cavity 2 can have fillers 3 of the same or different size, same or different non-metallic material.
  • the hollow spheres preferably consist of ceramic - in particular corundum - but they can also be made of glass or another non-metallic material.
  • the hollow spheres 13 or fillers 3 can be arranged in the cavities in a regularly layered orientation or position (see FIG. 1 on the right) or they are arranged in an irregular orientation with respect to one another in the cavity due to a bulk density with the greatest possible bulk density ( see Fig. 1 left, Fig. 2).
  • the remaining spaces are covered with a curable two-component plastic 8 such.
  • the packing can also before or after filling with an organic or inorganic binder such.
  • B. monoaluminum phosphate binder or a curable plastic can be bonded, glued or poured over, which after solidification causes the individual packing to hold together.
  • the individual bodies can also be connected to one another by sintering.
  • the outside diameter of the hollow balls used is advantageously in a range between 3 and 15 mm.
  • the cavity 2 is an outer armor plate 10 and an inner armor plate 11, for.
  • the preferably hollow spherical filler 3 are filled in together with the plastic or in succession through an opening 12.
  • the ratio of the volume V H of the cavity to the volume V of the packing should be greater than 100, preferably greater than 250. Packing bodies with an average diameter D M of at least 3 mm and a maximum of 15 mm result in the desired volume ratios with an advantageous cavity size.
  • the ratio of the volume of a cavity V H to the pure material volume V F of all inserted packing should be greater than 2. In such conditions, a good protective effect is achieved with the lowest possible weight of the armor device.
  • the gaps are then, as already described, with a two-component plastic, preferably with a foam, for. B. filled or foamed from polyurethane or can also be glued or poured over before or after filling with an inorganic or organic binder, which after solidification causes the individual packing to hold together.
  • a two-component plastic preferably with a foam, for. B. filled or foamed from polyurethane or can also be glued or poured over before or after filling with an inorganic or organic binder, which after solidification causes the individual packing to hold together.
  • the cavity filling with fillers and a two-component plastic can be produced in different ways.
  • Variant A Mix packing, first component and wetting agent and mix in second component shortly before filling into the cavity or into a mold.
  • Variant B Mix both components and packing and then fill in.
  • Variant C Fill in the packing, fill in the polyurethane mixture under overpressure or gravity.
  • This variant can also be used in the case of a position of the packing which is oriented to one another.
  • solid, hardened blocks 20 are to be produced from packing elements 3 and plastic for insertion into the cavities or for placement on plates, these can be reinforced with a wire mesh or expanded metal 21.
  • Blocks of this type are produced in a mold, the reinforcement 21 being first fixed in the mold and then the filler 3 and the plastic being filled in according to one of the methods A, B or C.
  • the block 20 between the packing 3 - preferably hollow spheres 13 - has several layers of plate-shaped elements 22, which preferably consist of ceramic or glass.
  • FIG. 5 A further embodiment variant of a block 21 is shown in FIG. 5, the plate-shaped elements 22 being arranged in several layers on the side of the block opposite the threat direction 4 and occupying approximately 1/3 of the height h of the block.
  • the plate-shaped elements 22 with a sheath 23 made of plastic such.
  • Blocks of this type can also be used as moduli in the case of a armor arm having a combined protective action against different types of projectiles, these moduli in particular forming protection against shaped charges.
  • the cavities or the hardened blocks can be arranged both on the outside and on the inside of an armor plate or a plate element and covered with a plate.
  • the optimization takes place with regard to strength, toughness, hardness, processability and / or by means of suitable reinforcement or cross-linking.
  • the layers with the plate-shaped elements 22 by packing 3, 13 are arranged with a much larger diameter than the other packing.
  • the difference in diameter of the packing used in the two different layers should preferably be in a ratio of 1: 3 to 1: 6.
