  • Patent number: 8789454
    Abstract: An armor system with a composite laminate having at least four alternating layers (two bi-layers) of a first material and a second material, the first material having a lower acoustic impedance than the second material. The first material is a viscoelastic polymer with a glass transition temperature less than the expected operational temperature range, and the second material can be a hard material such as steel, aluminum, or ceramic. The laminate can include many alternating layers of elastomer and hard material, and can be adhered or affixed to a thicker armor substrate. Additional protective elements such as corrugated metal-ceramic panels and armored glass cylinders can be added to improve resistance to armor piercing rounds, explosively formed penetrators, or other threats.

  • Publication number: 20130019740
    Abstract: A method for and apparatus absorbing the energy of a projectile strike by a multiplicity of energy dissipating elements of high mass that are contained within a spaced defined by walls. A projectile passing through one of the walls transmits its energy to a multiplicity of energy dissipating elements, such as hardened steel balls or various shaped objects of high mass, by causing energy transfer and distribution through a loose mass of the energy dissipating elements and disintegrating the projectiles. Energy absorbing apparatus embodying this method may take the form of a static or moveable bullet or projectile trap, an energy absorbing external barrier or shelter on vehicles, and portable personnel protection structures for use in a tactical environment. The energy absorbing and dissipating elements are subject to some movement in response to the energy imparted by the projectiles and quickly settle after the energy has been dissipated.

    Abstract: A utility vehicle with underfloor structure giving protection from mine explosions. There is a wedge at the edge of the driver compartment which splits the detonation blast from a mine buried in the track of a front wheel. There is a multilayer stack, inboard of the wedge, which crushes upward to reduce the detonation wave from a mine buried under the vehicle. The stack comprises panels to catch the detonation wave and separated by spacers. Spacers are longitudinal stringers stacked above each other and welded, forming deep beams joined to bulkheads, making the vehicle's frame. The wedge also bolts to bulkheads, augmenting the frame. In cross section, the stack is curved, tapering off at each end to merge with the “V” of a wedge. The wedge crushes sideways under the detonation wave, providing protection at the edge of the driver compartment where stack material has run out.

    Abstract: An armor uses optimally shaped ceramic cross-pellets and a matrix for containing the cross-pellets. The armor comprises front and back plates and an array of interlocking ceramic cross-pellets of repeating shape between front and back plates. Each cross-pellet may have a horizontal cross-section in the shape of a cross and comprises a center and four fingers projecting therefrom. Each cross-pellet in a non-peripheral portion of the array may be supported by fingers of other cross-pellets which may include two fingers from each of four other cross-pellets. The result is lightweight, composite hybrid structure. The dense, hard armor has good fracture toughness, hardness and a high capacity to absorb impacts for ballistic protection particularly suited to tactical ground vehicles. Valley spaced is minimized. A polymer resin may be situated in spaces between the ceramic cross-pellets and between the array and at least one of the back plate and front plate.

    Abstract: Blast energy absorption system capable of being integrated into the structure of a vehicle having removable, interchangeable, and configurable components adaptable to configure the vehicle for varying mission threats. The blast energy absorption system has a plurality of independent energy absorbing systems including one or more in combination of the following: a floor structure, a housing, cross beam members, adjustable energy absorbing containers, and an understructure. Each component may be an independent reactant system. The integral relationship between the above mentioned components forms a system that absorbs and distributes blast energy to minimize energy transfer to the occupants of the vehicle. Blast energy absorption system is capable of many configurations depending on the threat level of a mission.

  • Publication number: 20120180627
    Abstract: A blast attenuator includes an enclosure defining a cavity; a core defining a plurality of interconnected pores, the core disposed in the cavity; and a shear thickening fluid disposed in the cavity, such that the shear thickening fills a portion of a pore volume of the core. A blast attenuation assembly includes a blast attenuator including a shear thickening fluid and a crushable element that omits a shear thickening fluid operably associated with the blast attenuator. A method includes the steps of providing a rigid core defining a plurality of interconnected pores and placing an enclosure about the core, the enclosure defining a filling port. The method further includes the steps of filling at least a portion of a pore volume of the core with a shear thickening fluid and closing the filling port to seal the enclosure and form a first blast attenuator.

  • Publication number: 20120174747
    Abstract: An article of armor includes a friction material operative to prevent penetration of a ballistic projectile. The armor is also operative to prevent penetration of a plurality of ballistic projectiles at a single point of impact. The armor may include a backing, or a facing, or may comprise an intermediate layer between a backing and facing in any combination. The armor of the invention applied directly to or attached to an article to be armored so as to cover all or any portion of the article. The backing and facing may include a friction material or a non-friction material. The friction material is a composite of a resin binder agent, a fibrous support structure, a friction modifier system, and a wear system.

  • Patent number: 8215222
    Abstract: Ring-shaped shape memory alloys put disk-shaped ceramic materials in a state of compression. The rings are radially deformed to introduce plastic strain into the rings. The rings are sized to closely receive the disk-shaped ceramic strike plates. When the assembly is heated, the rings attempt to regain their original shape and thereby put the ceramic strike plates into uniform, two-dimensional compression.
