Layered Armor Containing Ceramic Material (epo) Patents (Class 89/906)
  • Patent number: 8815756
    Abstract: An armor panel provides a continuous armored strike face defined within a periphery. The panel is manufactured from a composite material having a plurality of armor tiles embedded in a polymeric matrix that is structurally reinforced by a layer of fiber fabric. The armored strike face may be contoured to accommodate the base upon which it will be mounted. In some applications, an armor system is assembled from at least two of the armor panels. In such a system, at least a portion of the periphery of each armor panel defines an internal seam edge of the armor system. Each such periphery portion is in a lapping relationship with the corresponding internal seam edge of another armor panel.

  • Patent number: 8695476
    Abstract: A composite armor plate includes a fracture layer placed adjacent to a ceramic layer. The ceramic layer provides a ballistic resistant layer that receives a ballistic impact and propagates a compression wave. The fracture layer is placed behind the ceramic layer and absorbs a portion of the compression wave propagating out in front of the ballistic impact. The absorbed compression wave causes the fracture layer to at least partially disintegrate into fine particles, which dissipates energy in the process. To cause a higher degree of fracturing (and thus larger dissipation of compression wave energy) the fracture layer includes a plurality of resonators embedded in a fracture material.

    Abstract: A resource is protected by an armor structure comprising a magnetic field such that the magnetic field will interfere with a warhead blast to weaken the blast. In particular, magnetic field will interfere with a molten metal jet from a shaped charge to disperse the jet, allowing subsequent layers of armor to absorb the jet energy without penetration. In one embodiment, the magnetic field is produced by a layer of magnetic material magnetized with the field lines perpendicular to the primary threat direction and typically parallel to the surface of the area to be protected. The magnetic material layer may include ferromagnetic (iron or steel, or other) layers to strengthen and contain the magnetic field, protect the magnetic material and act as additional armor layers. The magnetic layer is typically used in conjunction with an inner shield armor layer to absorb the diffused jet after passing through the magnetic layer.

  • Publication number: 20110290104
    Abstract: An apparatus for providing protection from ballistic rounds, projectiles, fragments and explosives. The apparatus includes a core, grinding layer and bonding layer. The core is shaped and configured as a structural truss of the apparatus, in which the core includes a plurality of parallel, adjacent rows and the core distributes and dissipates force impacting on the apparatus. The grinding layer is positioned on at least one side of the core facing towards potential threats, in which the grinding layer grinds rounds, projectiles, fragments or other materials impacting the apparatus, helping to dissipate the impacting material and its momentum. The bonding layer bonds the grinding layer together and the grinding layer to the core and provides an outer coating to the apparatus on a side of the apparatus facing potential threats and through which rounds, projectiles, fragments or other materials impact and penetrate the apparatus.

  • Publication number: 20110259184
    Abstract: A lightweight armor system according to the present invention includes one or more material layers having a fraction of void volume and at least one of those material layers having holes of various sizes and designs integrated therein. The material layers are infiltrated with liquid metal which solidifies within the materials open porosity to bind the layers together to create a coherent integral structure. The holes may be in the form of tubes which are impervious to metal infiltration and reduce the weight of the armor system while contributing to projectile deflection. A process for producing a lightweight armor system is disclosed which comprises the steps of 1.) forming holes in a preform containment layer 2.) positioning sealed tubes in the formed holes so that the tubes run through the thickness of the preform 3.) positioning at least one preform w/ sealed tubes within a mold chamber of a closed mold and 4.) infiltrating the mold with a liquid metal.

  • Publication number: 20110247481
    Abstract: The invention relates to a composite armor comprising multiple isolated reactive charges in various shapes and in various configurations. Charges are reacted and dynamically pressurize ceramic elements to reinforce the armor and to disrupt the projectile penetration process. In one embodiment of the present invention an armor comprising a multitude of high tensile strength enclosures are arranged in a closely packed pattern. A ceramic element is disposed in each individual enclosure; a thin inter-layer of explosive material is disposed between the ceramic element and the enclosure's strike face. In a ballistic event, the explosive is set off by an incoming projectile and the ceramic element is thus pressurized and reinforced.

    Abstract: A method and apparatus for defeating high-velocity projectiles. A plurality of disks of equal size comprised of fiber induced ceramic composites are provided. The disks are laid out in an imbricated pattern row by row such that each disk in a row is in substantially a straight line with the other disks in the row and overlaps a segment of a disk in an adjacent row. The imbricated pattern is then adhered to a flexible, high tensile strength substrate and overlaid by a second high tensile strength layer such that the imbricated pattern is enveloped between the substrate and the second layer. The envelope is then coupled to a soft body armor backing.

    Abstract: In some example, the disclosure provides armor assembly designs utilizing multiple solid armor plates and one or more coupling elements, such as, e.g., high-strength ropes, to couple the solid armor plates to each other. For example, the solid armor plates may be attached to one another and held in position via high-strength ropes for form a discontinuous armor layer. The armor assemblies may include multiple layer arrangements of the solid armor plates that provide substantially complete coverage of a surface when the multiple discontinuous layers are combined. Ropes or other coupling elements may be used to horizontally connect plates together within the same discontinuous layer of armor plates and ropes may also be used to vertically connect plates in different armor layers. In some example, the armor assembly may be highly flexible and breathable to provide body armor that may be comfortably worn. In some examples, armor assemblies may be adapted for use as vehicle armor or other armor applications.
