Definitions

  • the invention relates to the fields of materials sciences, ceramics, protective armor materials and wear and tear, and relates to high-strength endoplates for end-ballistic protection, for example for the protection of vehicles and persons, and for wear protection, for example for use in crushers, mills, Troughs and pipes and a method for their production.
  • Ballistic protective armor which consist of a backing material and applied tiles. These bullet-resistant sheet materials are bullet-resistant sheet-like structures with a textile laminate (backing material) onto which ceramic boards are adhesively bonded to one another in a form-fitting manner. This material composite should, with the lowest possible weight, make shots, especially of hard core projectiles with high speeds and thus high impact energy, ineffective. The introduced by the projectile Energy at the bullet point is dissipated in the west by the destruction of the affected tile.
  • the EP 0 967 453 A1 which forms a basis for independent claims 1 and 16, describes a flexible, impact or impact resistant composite material which has a shock side which is impact resistant and the adjacent plates have a completely blunt edge.
  • this composite material consists of a flexible material, which consists of at least one layer, which has a high resistance to local deformation and has non-ballistic properties.
  • the plates are integrated into the flexible material on the impact side.
  • the plates may have a variety of three-dimensional shape, such as cylindrical, pyramidal, truncated pyramidal or angular shapes.
  • the object of the invention is to provide high-strength fabrics for end ballistic protection and wear protection, in which only in the immediate vicinity of a projectile action or local wear the destruction of the fabric takes place and a simple method for their preparation
  • the flatness of the surfaces to the top and bottom depends essentially on the application, which may also require curved and / or curved surfaces.
  • the individual bodies and / or the composites composed thereof consist wholly or partly of ceramic and / or metallic materials, and particularly advantageously of ceramic materials, such as SiC, Si 3 N 4 , Al 2 O 3 , of metallic materials such as hard metals, higher strength Steel, such as V2A steel, ST 52-3 or ceramic-metal composites.
  • ceramic materials such as SiC, Si 3 N 4 , Al 2 O 3
  • metallic materials such as hard metals, higher strength Steel, such as V2A steel, ST 52-3 or ceramic-metal composites.
  • connection of the individual bodies by gluing, welding, soldering or by brackets is realized.
  • the individual bodies of the fabric have only one connection to the backing material and / or to another sheetlike material and then, conversely, to yield a complete fabric together.
  • the contact surfaces of the individual individual bodies are positively connected to one another.
  • the individual bodies and / or the mold assemblies composed therefrom have dimensions of 5 to 200 mm, more advantageously dimensions of 10 to 100 mm edge length.
  • gaps between the surfaces and / or edges of the individual bodies and / or the composite forms composed thereof are completely filled.
  • the filling may advantageously be an adhesive or a solder or a tissue.
  • the gaps between the surfaces and / or edges of the individual bodies and / or the composite forms composed thereof are advantageously between 0.1 and 10 mm wide, with smaller dimensions of the individual bodies and / or the mold composites also having smaller gap dimensions.
  • Destruction by projectile action or wear occurs only in the immediate vicinity of the projectile caliber or the wear and thus has an improved resistance to multiple impact or permanent wear due to wear.
  • This is achieved according to the invention by reducing the size of the individual bodies, which on the one hand has the disadvantage of a high number of surfaces with respect to the projectile or wear effect, but nevertheless achieves an improved bullet-resistant or wear-inhibiting effect.
  • This advantage is achieved by reducing the weaknesses of such a composite surface, which existed in the prior art, and / or were no longer arranged directly in the direction of impact of the projectiles or the wear. This advantage also applies to the field of wear protection, in which there is primarily an impact stress of the armor.
  • backing material used in the context of this invention is understood to mean a material to which individual bodies and / or one or more mold composites are attached or which completely or partially surrounds the individual bodies and / or one or more mold composites.
  • the backing material is advantageously fiber fabric molded body and in the case of wear protection advantageously metal, for example in the form of sheets.
  • metal sheets as backing material for Endbaflistica protection, as well as the use of fiber fabric moldings as backing material in wear protection is also conceivable.
  • the composite 400 pentahedron cover the entire backing material with their flat sheet side to the backing material. This sheet structure side is frictionally connected to the backing material by gluing with a two-component synthetic resin adhesive.
  • a fabric produced in this way is incorporated into a protective armor for a military vehicle.
  • the maximum destroyed area is 40 x 40 mm, but usually only 20 x 40 mm.
  • a continuously cast high-strength steel (ST 52-3) with a triangular cross section is processed by obliquely cutting the strand into pyramids with a footprint of 40 x 40 mm and a height of 40 mm. From such a steel strand and subsequent oblique cutting tetrahedrons are produced with a length of each right-angled edges of 40 mm and a height of 40 mm.
  • the pyramids and tetrahedra as a composite mold are each arranged in 200 pieces in a frame to a flat sheet.
  • the side facing the backing material is connected to the backing material made of a steel sheet of quality ST37 measuring 400 x 400 mm with a soft solder and appropriate flux.
  • a fabric produced is incorporated as a protective armor for the baffle plate of a hammer crusher.
  • the touching edges of the armor plates are more eroded than the plates themselves.
  • the pitch runs obliquely to the stress direction due to the arrangement of the tetrahedra and pyramids, which results in a reduced abrasion at the contacting edges, resulting in a use time that is longer by 11 ⁇ 2 times. Due to the solder joint replacement of the protective plates and a reuse of the safety device are possible.
