  • Publication number: 20070154702
    Abstract: A glassy carbon coated carbon foam material is formed by coating carbon foam with a glassy carbon layer. Carbon foam may be produced by carbonizing a phenolic or polyurethane foam at high temperatures in an inert atmosphere. The carbon foam is then machined to a desired shape and treated with a fine carbon or graphite powder to the surface. Subsequently a resin is applied to the surface of the carbon foam, and the coated carbon foam block is fired to carbonize the resin coating into a glassy carbon coating. The firing and coating are repeated until the desired coating thickness and surface properties are achieved.

  • Publication number: 20070155847
    Abstract: An activated carbon foam material with improved graphitizability is formed by including an oxidation promoting metal-containing additive into the carbon foam and subsequently heat treating the foam in a reactive atmosphere. The oxidation promoting metal-containing additive greatly improves the development of the carbon foam's ramified pore system resulting in a carbon foam with a much greater surface area. This inventive foam may be created by introducing the oxidation promoting metal by way of an oxidation catalyst during the polymerization of the phenolic resin or as a inorganic chemical activating agent to the formed phenolic resin. The foam is then heated in a reactive atmosphere to produce an activated foam with a surface area of from about 200 m2/g to about 3000 m2/g.

  • Publication number: 20070155848
    Abstract: A carbon foam material with an improved oxidation resistance is created by blending formaldehyde with phenol to form a reactive mixture, polymerizing the reactive mixture with a non-oxidation promoting basic catalyst to form a resin article, foaming the resin article to create phenolic foam, and carbonizing the phenolic foam to create the carbon foam with an increased oxidation resistance. Specifically, the oxidation resistant carbon foam has a sodium content of approximately 0%. This inventive foam may also contain one or more oxidization inhibitors to impede the oxidation of the carbon foam when the foam is exposed to an oxidizing environment.

  • Publication number: 20070155849
    Abstract: A reinforced carbon foam material is formed from carbon fibers incorporated within a carbon foam's structure. First, carbon fiber bundles are combined with a liquid resol resin. The carbon fiber bundles separate into individual carbon fiber filaments and disperse throughout the liquid resol resin. Second, the carbon fiber resin mixture is foamed thus fixing the carbon fibers in a permanent spatial arrangement within the phenolic foam. The foam is then carbonized to create a carbon fiber reinforced foam with improved graphitic characteristics as well as increased strength. Optionally, various additives can be introduced simultaneously with the addition of the carbon fiber bundles into the liquid resol, which can improve the graphitic nature of the final carbon foam material and/or increase the foam's resistance to oxidation.

  • Publication number: 20070154381
    Abstract: A carbon foam material with improved graphitizability is formed by including a graphitization promoting additive into the carbon foam. The graphitization promoting additive greatly improves the graphitic structure of the carbon foam resulting in a carbon foam with much greater thermal and electrical conductivities. This inventive foam may be created by introducing the graphitization promoting additive during the catalysis of a phenol-aldehyde mixture to a form phenolic resin or during the conversion of the phenolic resin to a phenolic foam. Alternatively, the graphitization promoting additive can be fixed onto a preformed carbon foam.

  • Publication number: 20060239889
    Abstract: A sugar/additive blend useful as a binder or impregnant for carbon products. Simple sugars as well as sucrose are combined either in solution or in solid form with reactive additives such as ammonium hydrogen phosphate, ammonium chloride and para-toluene sulfuric acid. The sugar/additive blends form more and denser carbon residue than sugar alone when subjected to pyrolysis.

  • Publication number: 20060192311
    Abstract: A process for preparing graphite articles is presented. In particular, the process includes employing a particulate fraction comprising at least about 35 weight percent coke, coal or combinations thereof having a diameter such that a major fraction of it passes through a 0.25 mm to 25 mm mesh screen. The particulate fraction is mixed with a liquid or solid pitch binder, to form a stock blend; the stock blend is extruded to form a green stock; the green stock is baked to form a carbonized stock; and the carbonized stock is graphitized. The stock blend further includes carbon fibers added after mixing of the particulate fraction and pitch has begun.

  • Patent number: 7006325
    Abstract: A picking tool for an automated library of disk drive carriers has a body with a large guide pin, and a pair of electromagnets. The guide pin has an optical service interface at its tip. A disk drive is mounted to a carrier having a front bezel with a tapered hole that is complementary to the guide pin. The hole provides access to an optical service interface linked to the disk drive. The bezel also has a pair of embedded magnets located adjacent to its front surface. The carrier is located in and interconnected with a slot in an automated disk drive library. The guide pin is inserted into the hole so that the interfaces interconnect. The carrier is removed from the slot by activating the electromagnets on the picking tool to attract the magnets in the bezel. The tool picker then pulls the carrier out of the slot while supporting the weight of the carrier on the guide pin. The carrier is released from the picking tool by reversing the current through the electromagnets to repel the magnets in the carrier.

  • Publication number: 20050274581
    Abstract: A mixture of carbon-containing fibers, such as mesophase or isotropic pitch fibers, a suitable matrix material, such as a milled pitch is compressed while resistively heating the mixture to form a carbonized composite material. Preferably, the carbonized material has a density of at least about 1.30 g/cm3. Preferably, the composite material is formed in less than ten minutes. This is a significantly shorter time than for conventional processes, which typically take several days and achieve a lower density material. A treating component may be impregnated into the composite. Consequently, carbon composite materials having final densities of about 1.6-1.8 g/cm3 or higher are readily achieved with one or two infiltration cycles using a pitch or other carbonaceous material to fill voids in the composite and rebaking.

  • Publication number: 20050003037
    Abstract: A mixture of carbon-containing fibers, such as mesophase or isotropic pitch fibers, and a suitable matrix material, such as a milled pitch, is compressed while resistively heating the mixture to form a carbonized composite material having a density of about 1.5 g/cm3, or higher. The composite material is formed in under ten minutes. This is a significantly shorter time than for conventional processes, which typically take several days and achieve a lower density material. Consequently, carbon/carbon composite materials having final densities of about 1.6-1.8 g/cm3, or higher are readily achieved with one or two infiltration cycles using a pitch or other carbonaceous material to fill voids in the composite and rebaking.
