  • Patent number: 6116202
    Abstract: An improved structure for carbon--carbon composite piston architectures is disclosed. The improvement consists of replacing the knitted fiber, three-dimensional piston preform architecture described in U.S. Pat. No. 4,909,133 (Taylor et al.) with a two-dimensional lay-up or molding of carbon fiber fabric or tape. Initially, the carbon fabric or tape layers are prepregged with carbonaceous organic resins and/or pitches and are laid up or molded about a mandrel, to form a carbon-fiber reinforced organic-matrix composite part shaped like a "U" channel, a "T"-bar, or a combination of the two. The molded carbon-fiber reinforced organic-matrix composite part is then pyrolized in an inert atmosphere, to convert the organic matrix materials to carbon. At this point, cylindrical piston blanks are cored from the "U"-channel, "T"-bar, or combination part. These blanks are then densified by reimpregnation with resins or pitches which are subsequently carbonized.

  • Patent number: 5947827
    Abstract: A method for reducing sliding friction of threaded fasteners according to the present invention includes the steps of providing a threadless austenitic stainless steel blank, coating the surface of the blank with a lamellar solid material, such as molybdenum disulfide, by introducing the threadless blank into a solution of molybdenum disulfide suspended within a carrying agent such as isopropanol or n-Butyl alcohol, heating the coated fastener to accelerate evaporation of the carrying agent, and forming threads into the coated surface using a thread rolling technique characterized by moving the blank through a series of traversing serrated dies moving in opposite directions parallel to one another to exert pressure on the coated surface, thereby both forming threads without removing metal from the surface, and impregnating the surface and near surface structure with the low friction species. Fasteners manufactured according to the present method exhibit reduced sliding friction and increased clamping force.

  • Patent number: 5948330
    Abstract: A three-dimensional piston molding is fabricated from a mixture of chopped, carbon tow filaments of variable length, which are prepregged with carbonaceous organic resins and/or pitches and molded by conventional molding processes into a near net shape, to form a carbon-fiber reinforced organic-matrix composite part. Continuous reinforcement in the form of carbon-carbon composite tapes or pieces of fabric can be also laid in the mold before or during the charging of the mold with the chopped-fiber mixture, to enhance the strength in the crown and wrist-pin areas. The molded chopped-fiber reinforced organic-matrix composite parts are then pyrolized in an inert atmosphere, to convert the organic matrix materials to carbon. These pyrolized parts are then densified by reimpregnation with resins or pitches, which are subsequently carbonized. Densification is also accomplished by direct infiltration with carbon by vapor deposition processes.

  • Patent number: 5927070
    Abstract: An improved exhaust system for an internal combustion gasoline-and/or diesel-fueled engine includes an engine exhaust manifold which has been fabricated from carbon-carbon composite materials in operative association with an exhaust pipe ducting which has been fabricated from carbon-carbon composite materials. When compared to conventional steel, cast iron, or ceramic-lined iron parts, the use of carbon-carbon composite exhaust-gas manifolds and exhaust pipe ducting reduces the overall weight of the engine, which allows for improved acceleration and fuel efficiency; permits operation at higher temperatures without a loss of strength; reduces the "through-the wall" heat loss, which increases engine cycle and turbocharger efficiency and ensures faster "light-off" of catalytic converters; and, with an optional thermal reactor, reduces emission of major pollutants, i.e. hydrocarbons and carbon monoxide.
