  • Patent number: 7211319
    Abstract: This invention relates to an aluminum conductor composite core reinforced cable (ACCC) and method of manufacture. An ACCC cable has a composite core surrounded by at least one layer of aluminum conductor. The composite core comprises a plurality of fibers from at least one fiber type in one or more matrix materials. The composite core can have a maximum operating temperature capability above 100° C. or within the range of about 45° C. to about 230° C., at least 50% fiber to resin volume fraction, a tensile strength in the range of about 160 Ksi to about 370 Ksi, a modulus of elasticity in the range of about 7 Msi to about 37 Msi and a coefficient of thermal expansion in the range of about ?0.7×10?6 m/m/° C. to about 6×10?6 m/m/° C. According to the invention, a B-stage forming process may be used to form the composite core at improved speeds over pultrusion processes wherein the speeds ranges from about 9 ft/min to about 60 ft/min.

  • Patent number: 7160607
    Abstract: A damping structure which dispenses of the connection of a resistor used for a conventional damping structure and undergoes diverse molding processings with a simpler structure, and a laminate damping base material constituting such a damping structure. A laminate damping base material made of a piezoelectric ceramic material or piezoelectric polymer material and a conductive fiber-reinforced plastic (FRP) composition is prepared. One to a plurality of this base material are stacked to constitute a first damping structure. A second damping structure is constituted by stacking at least a layer of piezoelectric polymer film or piezoelectric ceramic thin film between a multilayer laminate that is a laminate of conductive laminate FRP base materials.

  • Patent number: 7135233
    Abstract: Multi-layer composite structures offer improved weatherability and adhesion to fiber-reinforced plastic substrates when compared to structures now available. These composites have an outer layer made from a polyacrylate, a second layer made from an acrylonitrile-styrene-acrylate rubber terpolymer; a third layer made from an ABS polymer; and optionally a fourth layer made from a polyacrylate. The layers include one or more layers having an improvement selected from among: (a) the improvement wherein the second layer is made from an acrylate-modified acrylonitrile-styrene-acrylate rubber terpolymer; (b) the improvement wherein the third layer is a modified ABS that further includes a polymer modifier that decreases the softening of the ABS on contact with styrene, and an acrylonitrile-styrene-acrylate rubber terpolymer; and (c) the improvement wherein the fourth layer is present and is a polyacrylate. This composite can be applied to a fiber-reinforced plastic substrate such as fiberglass as a coating.

  • 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.

  • Patent number: 6919115
    Abstract: The present invention provides for a power transfer belt that is manufactured of a highly thermally conductive polymer composition, in contrast to the typical rubber material used to fabricate the belts of the prior art. The new and unique belt of the present invention is manufactured of a thermally conductive polymer material that is easily injection moldable into any desired shape and configuration. Further, the polymer composition is very thermally conductive, which assists in dissipating heat that is generated by the friction created during normal operation of the device. The new belt material and its construction allow heat to be conducted directly through the surface of the belt thus preventing heat buildup within the belt itself, thereby preserving and extending its life. Further, the present invention provides a novel method whereby a thermally conductive belt is manufactured through net shape molding.

  • Publication number: 20040142618
    Abstract: This invention provides facing materials for cementitious boards such as those including Portland cement or gypsum cores. The preferred facing material includes, in a first embodiment, a facing layer having an areal weight of about 300 grams/M2, and an air permeability rating of no greater than about 300 CFM/ft2 (FG 436-910 test method). The facing layer reduces the penetration of a slurry of cementitious material during the manufacture of a cementitious board, while permitting the water vapor from the slurry to pass therethrough. The facing materials of this invention can be designed to substantially eliminate the fouling of rolls used in continuous processing of such boards without the use, or with greatly reduced use, of costly viscosity control agents in the slurry.
