    Date of Patent: September 9, 2014
    Assignee: GrafTech International Holdings Inc.

  • Patent number: 8530094
    Abstract: A reduced puffing needle coke is formed, which includes a reduced nitrogen content within the coke so that the coke particles do not experience as much puffing during the formation of graphitized carbon articles produced from such coke upon heating to graphitization temperatures.
    Type: Grant
    Filed: July 21, 2011
    Date of Patent: September 10, 2013
    Assignee: Graftech International Holdings Inc.

  • Patent number: 8440302
    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: 20120009415
    Abstract: An article for tooling composite materials, including a carbon foam, a sealant attached to the carbon foam so as to form a monolithic fine-grain graphite-like surface; and a skin of facesheet materials. The facesheet materials include: a spray-deposited coating of metal; more preferably, a thermal or plasma spray-deposited metal; and most preferably, a plasma sprayed Invar metal. The facesheet materials may optionally include a flash coating. The facesheet materials alternately include plastics, resinous materials and carbon-carbon composite materials.
