  • Patent number: 8381631
    Abstract: Laminate armor and methods of manufacturing laminate armor. Specifically, laminate armor plates comprising a commercially pure titanium layer and a titanium alloy layer bonded to the commercially pure titanium outer layer are disclosed, wherein an average thickness of the titanium alloy inner layer is about four times an average thickness of the commercially pure titanium outer layer. In use, the titanium alloy layer is positioned facing an area to be protected. Additionally, roll-bonding methods for manufacturing laminate armor plates are disclosed.

  • Publication number: 20120181817
    Abstract: A field configurable vehicle armoring system and associated method allow a user to retrofit and reconfigure a combination of armor components in response to a perceived threat change and using original equipment manufacture fasteners and holes. The system includes pillar armor attachable after an original equipment manufacture door and hinge are removed. Fasteners extend through the hinge of the armored door, the pillar armor and an original equipment manufacture pillar using holes other than the original equipment manufacture holes. Rocker panel and underbody armor is further provided, along with a ballistic resistant windscreen and rear wall armor. Where desired, system armor includes a composite plate comprising a strike face that is constructed from softer metallic material than an inner metallic sheet.

  • Publication number: 20120174760
    Abstract: A dual hardness steel article comprises a first air hardenable steel alloy having a first hardness metallurgically bonded to a second air hardenable steel alloy having a second hardness. A method of manufacturing a dual hard steel article comprises providing a first air hardenable steel alloy part comprising a first mating surface and having a first part hardness, and providing a second air hardenable steel alloy part comprising a second mating surface and having a second part hardness. The first air hardenable steel alloy part is metallurgically secured to the second air hardenable steel alloy part to form a metallurgically secured assembly, and the metallurgically secured assembly is hot rolled to provide a metallurgical bond between the first mating surface and the second mating surface.

  • Publication number: 20120090451
    Abstract: An armor system for defeating a solid projectile has an outer armor plate, an interior armor plate, and an inner armor plate, the plates positioned approximately parallel to one another and also displaced from one another along the projectile trajectory to form a first dispersion space between the outer armor plate and the interior armor plate, and a second dispersion space between the interior armor plate and the inner armor plate. The first and second dispersion spaces are each sufficiently thick to allow significant lateral dispersion of any armor fragments passing therethrough.

  • Publication number: 20110308379
    Abstract: In accordance with an embodiment of the present disclosure, a protective armor system may include a first armor layer. The protective armor system may also include a plate that is detachably coupled to the first armor layer. The protective armor system may also have a second armor layer that is separated from the plate by a gap. When the plate is struck by a projectile, it may be operable to increase the surface area of the tip of the projectile as the projectile accelerates the plate through the gap.

The first dispersion space is sufficiently thick to allow significant lateral dispersion of armor passing therethrough. The inner armor plate is disposed approximately parallel to the interior armor plate and displaced therefrom to form a second dispersion space between the interior armor plate and the inner armor plate. The second dispersion space is sufficiently thick to allow significant lateral dispersion of materials passing therethrough.

  • Publication number: 20110252956
    Abstract: In one embodiment, two or more layers of aluminum alloys are metallurgically bonded and then wrought to produce an armor product having improved ballistics limits for resistance to armor piercing and fragment simulated projectile threats. In one embodiment, the armor product can include a composition that includes a continuous gradient of two or more aluminum alloy compositions. In one embodiment, the armor product can include layers of different aluminum alloys. In one embodiment, the armor product can include compositions of a mixture of more than one aluminum alloy. This armor may be useful on light armor vehicles having wheels, as well as planes and boats.

  • Publication number: 20110197745
    Abstract: A method for making armor plate that is resistant to armor piercing small arms ammunition is provided. The armor plate includes a steel plate having a nominal chemical composition in weight percent of 0.4C-1.8Ni-0.8Cr-0.25Mo. The steel plate is carburized on one side and produces a carburized side and a non-carburized side. The carburized side of the steel plate has a carbon concentration of at least 0.9% by weight and the non-carburized side has a carbon concentration of between 0.38 and 0.45% by weight. After the steel plate has been carburized, it is subsequently thermally processed such that the carburized side has a hardness of at least 58 Rockwell Hardness C (HRC), and the non-carburized side has a hardness of between >=50 and <=55 HRC.
