  • Patent number: 6358584
    Abstract: A tube reinforcement assembly is designed to reinforce complex tube structures, such as those having bends or varying inner diameters. The assembly includes a carrier and a plurality of spring-biased, deflecting wings around the carrier. The wings have structural foam layers on both surfaces that expand when heated. In one application, the wings of the assembly are compressed so that the assembly can fit around bends and narrow areas within the tube. Once the assembly is in its desired position, the structural foam is expanded and cured so that one expanded foam layer presses against the inner wall of the tube structure and the other expanded foam layer presses against the carrier of the reinforcement assembly.

  • Patent number: 6344268
    Abstract: Foamed polymer-fiber composites, building materials and methods of making such building materials are provided by this invention. The composites include about 35-75 wt. % of a polymeric resin, about 25-65 wt. % fiber and have a specific gravity of less than about 1.25 g/cc. The low density is provided by the introduction of a blowing agent or gas into a molten precursor of the composite during thermo forming, such as in an extrusion operation.

  • Patent number: 6337128
    Abstract: The present invention provides a pressure-sensitive adhesion sheet being excellent in moisture and heat resistance and having a high adhesion to inorganic materials such as glass and tile, particularly a high adhesion even under high temperature and high humidity conditions, without using a silane coupling agent. The pressure-sensitive adhesion sheet for a silicone oxide-containing material comprises a base material having formed on at least one surface thereof a layer composed of an acrylic pressure-sensitive adhesive, wherein the base material is selected from a foamed base material having a water absorption rate less than 15% by weight after having been immersed in warm water having a temperature of 40° C. for 24 hours and a plastic film having a water vapor permeability of 500 g or less/m2/24 hours, and the acrylic pressure-sensitive adhesive to be used in combination with the base material selected is specified.

  • Patent number: 6309743
    Abstract: A porous preform for manufacturing partially composite lightweight metal products including at least a sliding surface as composite part is made of a hard material which comprises a sintered mixture comprising TiO2 particles, short ceramic fibers and whiskers, and SiC particles having an average particle size of approximately 20 to 100 &mgr;m. The partially composite lightweight metal product produced from the porous preform is provided with superior wear resistance and high strength and achieves increasing the coefficient of friction even though it is large in size, so as to keep a composite part of the composite lightweight metal product such as a sliding surface of a brake rotor remain even and smooth for a long period of time.
