Abstract: An anti-ballistic barrier system with a top shield support, a bottom shield support, and an anti-ballistic shield. A first extendable connector may extend between the anti-ballistic shield and the top shield support. Similarly, a second extendable connector may extend between the anti-ballistic shield and the bottom shield support. A polyester shield cover may extend over the anti-ballistic shield. A top mounting bracket attaches the top shield support to a vertical structure and a bottom mounting bracket attaches the bottom shield support to the vertical structure. The anti-ballistic shield is movable between a retracted position in which the anti-ballistic shield is wrapped around the top shield support and the bottom shield support is detached from the bottom mounting bracket and an extended position in which a majority of the anti-ballistic shield is unwrapped from the top shield support and the bottom shield support is engaged with the bottom mounting bracket.

Abstract: A fabric comprising a first plurality of yarns, a second plurality of yarns and a third plurality of yarns wherein the first, second and third pluralities of yarns have a yarn orientation that is different from each other. The third plurality of yarns is oriented in an axial direction. The second plurality of yarns is interwoven with the first plurality of yarns. The third plurality of yarns have no crimp. The yarns of the second plurality of yarns have an average linear density greater than or equal to the average linear density of the yarns of the first plurality of yarns and the yarns of the third plurality of yarns have an average linear density greater than the average linear density of the yarns of the second plurality of yarns and less than three times the average linear density of the yarns of the first plurality of yarns.

Abstract: A fabric assembly particularly useful in soft body armor has two or more first 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. Each first section is comprised of connected and compacted fabric layers that are secured together by connectors having a force to break in tension not greater than 65 N. The connectors are concentrated along a series of parallel connector lines as viewed from the fabric on both outer surfaces of the first section, the connector lines being spaced from 1.8 mm to 51 mm apart defining regions between the connector lines where the fabric layers remain unconnected.

Abstract: A fabric assembly particularly useful as soft body armor has two or more 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. At least one of the sections in the fabric assembly is comprised of compressed fabrics attached by connector yarns having a force to break in tension not greater than 65N concentrated along a series of parallel connector lines as viewed from the fabric on both outer surfaces of the first section, the connector lines being spaced from 1.8 mm to 51 mm apart defining regions between the connector lines where the fabric layers remain unconnected.

Abstract: A woven fabric from yarn for use in the manufacture of ballistic projectile or puncture resistant articles where the fabric has a first plurality of parallel oriented yarns within the plane of the fabric interwoven with a second plurality of parallel oriented yarns within the plane of the fabric having a direction/orientation within the plane of the fabric different from that of the first plurality and where the crossing of any fiber yarn from the first plurality with a fiber yarn from the second plurality forms a pair of acute vertical angles having an angular measurement less than 90 degrees.

Abstract: Shear thickening fluid suspoemulsions are shown to exhibit unique material properties that have potential application in a broad range of fields of use. Suspoemulsions containing shear thickening fluids as immiscible blends exhibit a nontrivial shear thickening response for volume fractions as low as 10% of STF in the silicone emulsion. Measurements indicate that the system shows phase inversion and it is even possible to form materials with a cocontinuous microstructure with interesting, hysteretic, shear sensitive behavior. Novel STF containing composites with rubbers are formed by blending the shear thickening fluid within the rubber precursors and then adding the catalyzing agent. It was possible to contain STF in each of the silicones tested and the rubbers exhibited different behavior with incased STF. Shear thickening fluid was added to open cell polyurethane to create a Foam-STF composite which was found to exhibit an significant shear thickening response.

Abstract: The present invention relates to body armor articles for resisting ballistic objects. The articles comprise woven fabric layers and sheet layers. The woven fabric layers are made from yarns having a tenacity of at least 7.3 grams per dtex and a modulus of at least 100 grams per dtex. The sheet layers comprise nonwoven random oriented fibrous sheets, each of the sheet layers comprising a uniform mixture of 3 to 60 weight percent polymeric binder and 40 to 97 weight percent non-fibrillated fibers. The woven fabric layers and the sheet layers are stacked together comprising a first core section which includes at least two repeating units of, in order, at least one of the woven fabric layers then at least one of the sheet layers. The sheet layers comprise 0.5 to 30 wt % of the total weight of the article.

Abstract: A multilayer, unitary gasket including at least one inner layer of expanded PTFE disposed between a first substantially air impermeable outer layer and a second substantially air impermeable outer layer, and a substantially air impermeable region bridging the first and second substantially air impermeable layers. The inventive gasket forms a substantially air impermeable seal when compressed at low stress.

Abstract: Polytetrafluoroethylene coagulate obtained from aqueous dispersion polymerization of tetrafluoroethylene in the presence of volatile initiator, surfactant, and possibly wax, is purified of these contaminants by exposing the coagulate to heated air with the coagulate being formed as a shallow bed on a fabric of polymer filament, the heated air passing through the bed from top to bottom to volatilize the contaminants including the water content of the coagulate and thereby cause them to leave the bed through openings in the fabric.
