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.

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.

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.

Embodiments of entrapment systems and apparatuses are generally described herein. Other embodiments may be described and claimed. In one embodiment, an entrapment apparatus is provided. This entrapment apparatus is comprised of a casing and a piece of multilayered fabric packed into the casing. The piece of multilayered fabric, when deployed, is configured to wrap around a person having an explosive device and configured to contain packed metal projectiles from an explosion of the explosive device.

A protective covering system (1) having high-flexibility and low areal density characteristics. In one aspect of the invention, the protective system (1) includes a plurality of metallic staples (2) or wire elements secured to multi-layer matrix (1) including woven fibers, the layers (1a, 1b, 1c) being oriented at cross angles to provide a grid-like pattern of protective elements (2). In one aspect of the invention, protective elements (2) provide a coverage area of less than 90% and as little as 40% of total surface area. In one aspect of the invention, protective elements (2) may be mechanically secured to a matrix (1) by a puncture and crimp process. In another, wire elements may be attached or woven into one or more matrix layers.

A laminate is disclosed for high strength, low weight gas enclosure applications such as aerostats or airships. The laminate is formed of at least one woven fabric layer with an aggregate strength greater than 10 grams per denier. The yarns in the fabric have sufficient twist to provide the desired tensile conversion but less than the amount of twist that would produce unsatisfactory flex fatigue. The fabric has a yarn to fabric strength ratio sufficient to impart tear resistance to the fabric, but less than the coarseness ratio at which flex fatigue performance is unsatisfactory, and the fabric has the minimal number of crossing points among the woven yarns that will impart sufficient integrity for the fabric to be manufactured into the laminate. A gas barrier material is then laminated to the fabric layer.
