Ballistic Resistant Patents (Class 442/135)
  • Patent number: 10006744
    Abstract: A ballistic resistant panel can be configured to be quickly and easily installed in a vehicle door. The ballistic resistant panel can include a plurality of ballistic sheets arranged in a stack. The stack can have an outer perimeter sized to fit within a cavity of the vehicle door. The panel can include a cover disposed over the stack, and the cover can be sealed around a perimeter of the stack to form a waterproof barrier that prevents moisture from reaching and altering the performance of the ballistic sheets. At least one anti-wear strip can be adhered to an outer surface of the cover. The anti-wear strip can provide a low friction surface that protects the panel from damage caused by moving internal door components, such as moving window components that repeatedly rub against the panel.

  • Patent number: 8679613
    Abstract: This invention relates to the use of an open, plain Leno Aramid fiber weave wrapped around the armor base plate in such a fashion that the wrap on the strike face surface is bonded with a thermoset resin while the continuous fibers around the back are left resin-free and able to distort, allowing localized deformation while keeping the remainder of the “wrap” holding tight. This wrap technique keeps the composite backing tight to the strike surface while allowing all of the benefits of localized fiber movement and tensile failure on the backside of the target. Other high performance fibers, such as fiberglass, also woven in a Leno weave and applied in the same method will yield similar results. This invention also relates to the placement of a “slip layer” between the fiber surface and the polymer coating of an armor system.

    Abstract: An article is provided that includes a polymeric fiber that has an excess number of surface active reactive moieties relative to the number of surface reactive moieties found on the fiber in a native state. A particle is bonded covalently to the fiber through an intermediate coupling agent. Multiple particles can be covalently bonded to the fiber, the multiple particles can be bonded uniformly or asymmetrically around the fiber diameter. A process for modifying a fiber includes creating surface activated reactive moieties thereon. The activated fiber is then exposed to a liquid solution containing a coupling agent to form a covalent bond. The coupling agent is also reacted with a particle in a liquid solution to form a covalent bond between the coupling agent and the particle. The coupling agent is covalently bonded to either a particle and then bonded to the fiber, or vice versa.

  • Patent number: 8287987
    Abstract: A ballistic-resistant panel in which the entire panel or a strike-face portion thereof is formed of a plurality of sheets of high modulus high molecular weight polyethylene tape. The sheets of high modulus polyethylene tape can be in the form of cross-plied laminated layers of tape strips or a woven fabric of tape strips. The strips of UHMWPE tape include a width of at least one inch and a modulus of greater than 1400 grams per denier. The ballistic-resistant panel may include a backing layer of conventional high modulus fibers embedded in resin. A wide variety of adhesives were found acceptable for bonding the cross-plied layers of high modulus polyethylene tape together for forming the ballistic-resistant panels of the present invention.

  • Patent number: 8268737
    Abstract: Electron beam curable resins or ultraviolet light curable resins can be used in combination with filler and other additives to make coated facers that can be used on insulation boards. Also disclosed are facers made of such composition, the process for making said facers and their use in insulation, building and construction boards. More specifically a flexible facer can be made by a process that comprises (1) applying a monomeric composition to a fiber mat, wherein the fiber mat is a non-asphaltic, non-cellulosic fiber mat, and wherein the monomeric composition is comprised of at least one monomer and/or at least one oligomer, and a filler, (2) initiating polymerization of the monomer within the monomeric composition by exposing the monomeric composition to ultraviolet light or an electron beam, and (3) allowing the monomer to polymerized to produce the flexible facer.

  • Patent number: 8256019
    Abstract: A ballistic resistant composite material useful in rigid armor applications. The composite material includes at least one consolidated network of high tenacity fibers in a thermoplastic matrix material. The resin is a thermoplastic polyurethane resin that is semi-crystalline at room temperature. The high tenacity fibers have a tenacity of at least about 7 g/d. Prior to consolidation the polyurethane resin matrix material is in an aqueous medium. When dry, the polyurethane matrix material has a tensile modulus (at 100% elongation) of at least about 500 psi (3.45 MPa), a tensile modulus (at 300% elongation) of at least about 500 psi (3.45 MPa), and an ultimate tensile strength of at least about 2000 psi (13.78 MPa). The ballistic resistant composite material has improved ballistic properties.

  • Publication number: 20120164371
    Abstract: A fabric assembly particularly useful in ballistic resistant armor has two separate sections each containing a number of fabrics made from yarns having a tenacity of at least 7.3 grams per dtex and a modulus of at least 100 grams per dtex. Compressed fabrics in the first section are employed and are connected by connectors that have a force to break in tension not greater than 180 N and are spaced apart by between 6 to 51 mm. Fabrics in the second section have at most a small amount of compression and are not joined other than to prevent slippage of the fabrics relative to one another.
