  • Patent number: 7326463
    Abstract: Circuit conductors and cables are formed of a conductive loaded resin-based material. The conductive loaded resin-based material comprises micron conductive powder(s), conductive fiber(s), or a combination of conductive powder and conductive fibers in a base resin host. The percentage by weight of the conductive powder(s), conductive fiber(s), or a combination thereof is between about 20% and 50% of the weight of the conductive loaded resin-based material. The micron conductive powders are formed from non-metals, such as carbon, graphite, that may also be metallic plated, or the like, or from metals such as stainless steel, nickel, copper, silver, that may also be metallic plated, or the like, or from a combination of non-metal, plated, or in combination with, metal powders. The micron conductor fibers preferably are of nickel plated carbon fiber, stainless steel fiber, copper fiber, silver fiber, aluminum fiber, or the like.

  • Publication number: 20080005860
    Abstract: A brush bristle material has at least one kind of diamond abrasive grains or abrading grains contained in a mixed state in a synthetic resin material formed of single threads. The synthetic resin material, while being formed into a linear material from chips, is caused to contain in a mixed state the abrasive grains and eventually manufactured into one brush. A plurality of at least one kind of brush bristles are bundled and consequently finished as a brush bristle material. The covering containing in a mixed state the abrasive grains encloses the bundle from the part excluding the part fixed by the tubular body through the distal end part. Though the brush bristle material has been at a disadvantage in revealing weak nerve due to a large bristle height, the covering has succeeded in canceling the disadvantage. This invention concerns a brush bristle material and a brush for a tubular brush or a segment brush having a large brush bristle height.

  • Patent number: 7151129
    Abstract: The resin in a fiber-reinforced resin material that uses a single fiber reinforcing ply or a number of fiber reinforcing plies for reinforcing the resin material is reinforced by dispersing carbon nanofibers therein, whereby a fiber-reinforced composite resin material having improved strength such as compressive strength is provided. In a carbon nanofiber-dispersed resin fiber-reinforced composite material 1, an uncured resin 4 having carbon nanofibers 5 dispersed therein is impregnated into a number of fiber reinforcing plies 2a laid one upon another. Upon curing the resin 4, the strength of the matrix 3 itself is increased through the carbon nanofibers 5 dispersed in the resin 4. Moreover, the fiber reinforcement 2 and the resin 4 are joined together strongly by the carbon nanofibers 5, and hence the strength of the composite material, for example the compressive strength, which hitherto has been dependent on the strength of the resin 4 only, is improved.

    Abstract: Silicon infiltration technology is used to produce ceramic bodies having utility as ballistic armor. In a first aspect of the invention, the ballistic armor includes a reaction-bonded silicon carbide body (RBSC). Good ballistic performance can be advanced by loading the permeable mass or preform to be infiltrated to a high degree with one or more hard fillers, and by limiting the size of the largest particles making up the mass. In a second aspect, the silicon infiltration technology, e.g., siliconizing or reaction-bonding, is used to bond silicon carbide fibers to at least the back surface of a ceramic armor body, thereby enhancing ballistic stopping power. A third aspect of the invention pertains to the ability to engineer RBSC bodies such that there is little dimensional change during processing, thereby permitting high dimensional reproducibility in large-scale production.

  • Patent number: 6551709
    Abstract: This invention relates to a method of inhibiting catalyzed oxidation of carbon-carbon composites involving the steps of treating a carbon-carbon composite having pores with a liquid composition, preferably an aqueous solution, containing (a) phosphoric acid, (b) a zinc salt, and (c) an aluminum salt and heating the treated carbon-carbon composite to a temperature sufficient to form deposits within the pores. In one aspect, the deposit comprises a dispersion of aluminum-rich phosphate in zinc-rich phosphate. This solution may be used in combination with a silicon carbide barrier coating, applied by either painting or by CVD, to allow application at higher temperatures. The adherence of the barrier coating may be improved by preoxidizing the surface to increase porosity at the surface. Articles, including friction brakes, and the aqueous compositions are also part of this invention. The methods and articles show improved penetration and retention of the catalyzed oxidation inhibitors.

  • Patent number: 6506482
    Abstract: A reinforced vitreous carbon composite suitable for use in the formation of wear-resistant assemblies, such as joint prosthetic devices, bearings, current collectors, sealing components, brake linings, electrical motor brushes, and other tribological products. The reinforced composite is formed by impregnating a metal reinforcement structure with a furfuryl alcohol resin, and polymerizing the resin while thermally managing the polymerization process, to produce a poly(furfuryl) alcohol continuous phase that is isotropic, homogeneous and essentially completely void-free, e.g., in a bulk composite form having dimensions greater than 25 millimeters in each of the x, y and z directions thereof.

  • Patent number: 6436508
    Abstract: The present invention relates to absorbent article such as sanitary napkins and panty liners comprising a topsheet, absorbent core, and backsheet which are breathable by the incorporation of a breathable backsheet and have a reduced tendency to exhibit garment wet through. The backsheet comprises at least one air permeable layer such as an apertured formed film or fibrous layer which is applied and preferably coated with a non-soluble, liquid swellabe material, such as polyvinyl alcohol. Upon contact with fluid discharge, the material swells and closes the apertures of the layer, thereby reducing air permeability and preventing the passage of liquid through the layer and thus through the backsheet onto the garment of the wearer of the article.
