  • Publication number: 20140331375
    Abstract: A protective garment system fabricated from ballistic textiles having a V50 on 2 grain RCC of at least 300 fps as measured by Mil-Spec 662F provides good ballistic and fragmentary protection, and can be worn in lieu of conventional clothing without discomfort to the wearer. Embodiments overcome prior art ballistic fabric limitations by incorporating novel construction, such as plaiting and/or twill or satin weaving, as well as novel yarn selection, to enable comfortable skin contact, and by applying coatings to improve abrasion resistance, UV resistance, and color acceptance. Embodiments incorporate layers of ballistic fabric in critical areas, either by overlapping protective clothing articles, and/or by incorporating multiple layers of protective fabric into an individual protective garment. Embodiments provide good moisture transport for long term comfort.

  • Publication number: 20140272361
    Abstract: A new class of protective fabrics having good ballistic and fragmentary protection also provide wearable drape, softness, and moisture transport, as well as good UV and abrasion resistance and color acceptance, making them comfortable to wear as garment fabrics. The protective fabrics are constructed from yarns having at least 20% ballistic fibers with greater than 12 gpd tenacity. A combined cover factor of between 55% and 80% avoids added stiffness due to yarn distortion at the crossing points. In embodiments, a long-float weave such as twill or satin with reduced crossing point density improves the hand of the fabric, and in some embodiments provides a different character on each face so that a predominantly staple fabric face is in contact with skin of a user, thereby providing better wearing comfort than a plain weave.

  • Patent number: 8809210
    Abstract: A self-decontaminating fabric is manufactured from fibers such as Tencel having high surface energy and low surface roughness. Novel scouring methods eliminate substantially all contaminants from the fibers, and a novel coating process applies an anti-pathogen coating such as a halogen compound to the fabric so as to provide rapid deactivation of pathogens on contact. Novel charging methods activate or reactivate the coating, typically by exposure to chlorine. The coating is substantially free of gap regions where pathogens can survive. The high surface energy of the fibers allows a high coating concentration and provides close contact between attached pathogens and the coating. The low surface roughness reduces the pickup of pathogens by the fibers. Multi-layer embodiments include an outer layer configured for maximum anti-pathogen coating concentration, and an inner layer configured for a reduced coating concentration that is compatible with skin contact.

  • Publication number: 20140026290
    Abstract: A 3D hand-shaped glove includes a performance-enhancing layer laminated to a fabric glove shell. A flat, solid laminate preform can be prepared with printed graphics, fabric layers, oriented films, dense and/or concentrated fillers, and other features. The 3D hand-shaped glove shell is placed on a 3D laminating form, and the preform is laminated thereto while preserving the 3D shape. In embodiments, the laminating form includes opposing flat surfaces, and a platen or roller press is used. In other embodiments, a bladder or vacuum bag press is used to laminate the preform to a curved or otherwise shaped surface of the laminating form. In embodiments, edge peel resistance is enhanced by extending the perimeter of a low modulus upper layer beyond underlying layers and bonding it directly to the glove shell. Recovery of the glove shell after deformation by the laminating form can provide a warping deformation of the laminate preform.

  • Publication number: 20140030483
    Abstract: A lightweight, low bulk, mobile CB shelter fabric includes a high tensile strength woven scrim laminated between two thin CB-impenetrable polymer films. Laminate adhesives can include isocyanate adhesion promotors. Coatings can be applied to the films for camouflage, increased light opacity, increased CB protection, sun, fire, and weather resistance. Lamination heat and pressure can cause the films to conform and bond through the scrim, while a pre-applied coating does not flow and remains uniform in thickness. The resulting fabric weight can be approximately 50% of conventional CB fabrics. The films can be hard-drawn polymers. A coating of hammer milled kaolin clay can provide increased light opacity. The films can be 1 micron thick, and can be nylon, aliphatic nylon, urethane, or poly-ether. The scrim can be a 1500 denier vectran with a 4.5 ends-per-inch warp and a 3.5 ends-per-inch fill. The scrim yarns can be flattened bundles of untwisted fiber.

  • Patent number: 8534178
    Abstract: A flexible armor system includes a rigid panel of a stiffness calculated to resist penetration by a known ballistic object, made from multiple layers of Ultra High Molecular Weight Poly-Ethylene fibers or other high tenacity fibers, which is then pre-flexed beyond its elastic bending limit to create a distributed pattern of surface buckling, with localized areas of interior delamination, which together function as bending or hinge lines to provide flexibility to the otherwise rigid panel and thereby lower its overall stiffness to less than that calculated for the rigid panel to resist the ballistic object. The areas of delamination have a width of less than one half the diameter of the ballistic object.

  • Patent number: 8468925
    Abstract: A non-lethal, sabot-deployed blast shield mitigates a suicide bomber by wrapping around the bomber and positioning a plurality of protective layers over an explosive device to absorb emitted heat, shock waves, and projectiles if the device is detonated. Stand-offs such as inflatable beams or pillows provide break-away zones between the protective layers, allowing some layers to expand to a point of failure and absorb the maximum possible energy. Inner layers absorb shock waves and heat. One or more outer layers resist projectile penetration. Protective layers can be positioned on opposing sides of a suspect in case two explosive devices are present. Shields can deploy with sufficient energy to knock down a bomber. In embodiments, a plurality of shields can be applied without interference therebetween. In some embodiments, a round shield includes bolas which spread the shield in flight in a cast-net dynamic and wrap around the suspect for shield attachment.

  • Publication number: 20120219609
    Abstract: A moisture-permeable glove or other garment protects against user contamination and cross-contamination by providing both rapid and persistent sterilization. Exposure to halogen of inherent NH groups and/or attached hydantoin can form a persistent outer halamine sterilization layer. A second inner halamine layer intercepts any pathogens that penetrate the outer surface. The garment can be single layer, or can include a detachable inner liner. Embodiments are compatible with rapid decontamination using an alcohol-based agent. Some embodiments provide a 180 second 3-log kill rate for at least S. aureus ATCC and E. coli. Embodiments include a moistening agent to activate the halamine. An anti-cut/puncture layer and/or a pathogen barrier layer can also be included. The protective layer can include contiguous layers of soft and hard metal flexed to improve flexibility and Moisture Vapor Transport Rate (MVTR). The pathogen barrier can include urethane and/or CNT fibers. The garment MVTR can be greater than 0.

  • Publication number: 20120159680
    Abstract: A modular and field adaptable body armor system includes a plurality of flexible, air-permeable, thermally vented plates arranged in fixed relationships that pro-vide flexible, modular, field-adaptable protection for the torso and extremities without excessive weight or heat bur-den. The TVA plates include protective cards suspended in a parallel, louvered relationship between inner and outer mesh layers, thereby permitting air to flow therebetween while providing a flexible, compressible, modular barrier that protects the torso and extremities against projectiles. In embodiments, the outer mesh layer resists penetration and compresses cards together to intercept a projectile that would otherwise pass therebetween. Protective cards can include thermally pressed and flexed laminated UHMWPE. TVA panels can be removed and exchanged in the field according to the requirements of each mission. In embodiments, the TVA plates are laced together and/or attached to an underlying fabric carrier garment.

  • Publication number: 20110023697
    Abstract: A flexible armor system adaptable to a garment suitable for extremity protection uses a planar array of polygon-shaped solid elements which detach upon projectile impact and combine their mass with the projectile for reduced velocity and increased impact area. The solid elements are bonded between an elastic strike-side spall cover and a high tensile strength flexible backer layer, and are further supported by a substantial fiber pack. In embodiments, the solid elements are ceramic, and are commutated but remain essentially intact after the projectile impact. Edge bars can cover junctures between solid elements, and center buttons can cover intersections between the junctures. Edge bars and center buttons can also be ceramic. The ceramic parts can include titanium backing layers. After formation, ceramic cores can be compressed upon cooling by an outer ceramic layer having a higher coefficient of thermal expansion, the outer layer being formed by glazing or doping.

  • Patent number: 7874239
    Abstract: A flexible armor system adaptable to a garment suitable for extremity protection uses planar, polygon-shaped solid elements made of ceramic cores wrapped in high strength fabric and arranged with rotable edge and intersection protection as a flexible mosaic array which is bonded between an elastic strike side spall cover and a high tensile strength flexible backer layer, further supported by a substantial fiber pack. A progressive mode of localized system failure during a ballistic strike includes: a projectile penetrating the spall cover, fracturing the ceramic core of a wrapped SE while being partially deformed; the deformed projectile accelerating the fractured but still wrapped solid element before it so as to free the solid element from the array and drive it through the flexible backer as a combined mass at a reduced velocity into the fiber pack.
