  • Patent number: 8956556
    Abstract: The present application is directed to dielectric isolators for use in aircraft fuel systems to control lightning induced current and allow dissipation of electrostatic charge. The dielectric isolators are configured to have a high enough impedance to limit lightning currents to low levels, but low enough impedance to allow electrostatic charge to dissipate without allowing buildup. Although the dielectric isolators may develop a potential difference across the dielectric length due to the effects of lightning currents and its inherent impedance, they are configured to withstand these induced voltages without dielectric breakdown or performance degradation. In one embodiment, the dielectric isolator includes a tube constructed of a composition including a thermoplastic organic polymer (e.g., PEEK) and carbon nanotubes, and a pair of fittings attached to opposing ends of the tube.

  • Publication number: 20130273280
    Abstract: A continuous fiber composite is described and methods for forming the continuous fiber composite. The continuous fiber composite includes a plurality of unidirectionally aligned continuous fibers embedded within a polyarylene sulfide polymer. The continuous fiber composite includes a very high loading of continuous fibers, for instance greater than about 40% by weight of the continuous fiber composite. The continuous fiber composite is formed by reacting a starting polyarylene sulfide with a reactively functionalized disulfide compound in a melt processing unit. Reaction between the starting polyarylene sulfide and the reactively functionalized disulfide compound leads to formation of a reactively functionalized polyarylene sulfide. Upon embedding of the continuous fibers into the reactively functionalized polyarylene sulfide, the reactivity of the polyarylene sulfide can enhance adhesion between the polyarylene sulfide polymer and the fibers.

    Abstract: A fibrous nonwoven mat particularly suited for hiding the color of a substrate when the mat is bonded to the substrate is made by forming a web of fibers from a wet fibrous slurry, saturating the mat with a resinous binder containing 1-20 weight percent of a paper coating material, removing excess binder from the mat to produce a mat having a resin binder content of 5-25 weight percent and drying the mat. The mat has high hiding power for substrates like board or blanket of fiber glass insulation and other colored materials.

  • Patent number: 7316840
    Abstract: Elastomeric composites and elastomeric composite laminates including reinforcement strands incorporated into an elastomeric adhesive film. The strands may vary in terms of levels of tension. Facing layers, such as nonwoven webs, can be laminated to both surfaces of the elastomeric composite to form laminates. A method of making such composites and laminates involves adjusting tension among various elastic strands while extruding the elastic strands and incorporating the elastic strands into the elastomeric adhesive film.

  • Publication number: 20070292674
    Abstract: Disclosed are composites that can exhibit low transmission energy loss and can also be temperature resistant. The composites include reinforcement fibers held in a polymeric matrix. The reinforcement fibers can include an amorphous polymer component. The fibers can be woven or knit to form a fabric or can be included in a nonwoven fabric. The composites can include other fibers as well, such as fiberglass. The composites can be multi-layer structures and can include layers of other materials, for instance layers formed of polyaramids, fiberglass, or carbon fiber wovens or nonwovens. The composites can advantageously be utilized in low loss dielectric applications, such as in forming circuit board substrates.

  • Patent number: 7247265
    Abstract: An auxetic material, which has a negative Poisson ratio so that it has the property of expanding or contracting transversely to a direction in which it is extended or compressed, is made in filamentary or fibrous form. A suitable process involves cohering and extruding heated polymer powder so that the cohesion and extrusion is effected with spinning to produce auxetic filaments. Typically the powder is heated to a temperature sufficient to allow some degree of surface melting yet not high enough to enable bulk melting.

  • Patent number: 7025825
    Abstract: A concrete article comprised of concrete having therein a reinforcing fiber, where at least about 50 percent of the reinforcing fibers are frayed only at an end or ends of the reinforcing fibers, may be made by mixing concrete, water and a reinforcing fiber for a sufficient time to fray the ends of at least 50 percent of the fibers and curing the mixture to form the concrete article. The fiber may be a reinforcing fiber comprised of at least two filaments bonded together and the filaments being comprised of a polymeric core and a polymeric sheath comprised of a fusing-fraying polymer, such that the reinforcing fiber, when mixed with inorganic particulates, frays predominately only at an end or ends of the fiber.

  • Patent number: 7011730
    Abstract: A method to produce a papermaker's shoe press belt or other industrial process belt and a belt made according to such method. The belt is produced by dispensing a mixture of polymer and staple fiber onto a cylindrical mandrel, by extrusion or by co-extrusion. Preferably, the variation of the concentration and/or orientation of the staple fiber within the polymer is controlled such that the finished belt has desired properties.
