  • Publication number: 20020016118
    Abstract: 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.

  • Patent number: 6294488
    Abstract: A flexible composite expansion joint material comprises a fluoropolymer containing woven fabric substrate with mutually perpendicular warp and fill yarns. The substrate is subdivided into plural segments which are arranged successively in a longitudinally extending assembly with the warp and fill yarns of each segment extending obliquely with respect to the assembly length. At least one other component extends over the assembly length. The successively arranged substrate segments are spliced together and integrally joined to the other component by lamination under conditions of elevated temperature and pressure.

  • Patent number: 6228444
    Abstract: A tubular structure comprising reinforcing fibers impregnated with a thermosetting polymer and a sheet of matrix material filled with an additive suitable for improving tribological and heat conductivity characteristics of the tubular structure. The reinforcing fibers alternate with the matrix material. The tubular structure is formed by winding the reinforcing fiber fabric and the matrix sheet material, wherein the fabric and the matrix sheet material have first and second ends and the first ends are located in the interior of the winding and the second ends are radially outwardly displaced from the first ends.

  • Patent number: 6217964
    Abstract: An endless belt for use in digital imaging systems is provided having uniform edge to edge flatness, and precise circumferential and edge to edge thickness. The layers comprising the belt may be tailored as desired for use in either latent image formation, image transfer or sheet transport operations. In one embodiment, the belt includes an elastomeric base layer, an intermediate polymer ply over the base layer, and an outer elastomeric layer. Alternatively, the belt includes an elastomeric base layer and an outer polymer layer. The belt may further include reinforcing layers which may comprise a woven or non-woven fabric layer and/or an elastomerimpregnated spun cord layer. The belt is preferably manufactured by building the layers on a workpiece and then curing the layers.

  • Patent number: 5948707
    Abstract: A non-slip, waterproof, water vapor permeable fabric and method of making are described. The fabric is made by obtaining a waterproof, water vapor permeable film and adhering one side of the film to a layer of fabric which may be a stretch fabric. The other side of the film is provided with a discontinuous coating of an elastomer which has an elastic modulus of less than 5.5N/mm.sup.2. The discontinuous coating may take various forms including a pattern of dots or a grid of intersecting lines. The discontinuous coating may optionally project above the surface of the film. The presence of the discontinuous coating of elastomer results in a fabric with a static coefficient of friction of greater than about 1.0 on the discontinuously coated side of the fabric. The film is preferably a porous expanded polytetrafluoroethylene film provided with a hydrophilic coating on one surface; the hydrophilic coating may serve as an adhesive for joining the one surface of the film to the layer of fabric.
