20080275150 | Carbon Foam With Supplemental Material - A carbon foam composite including a carbon foam skeleton having a supplemental material therein, the composite useful for, inter alia, a variety of applications including applications requiring durability and water resistance. Also included is a method for making such carbon foam composite materials. | 11-06-2008 |
20090294325 | Reduced Puffing Needle Coke From Coal Tar - A reduced puffing needle coke is formed, which includes a lesser amount of nitrogen within the coke so that carbon articles produced from such coke experience minimal expansion upon heating to graphitization temperatures. | 12-03-2009 |
20090294326 | Reduced Puffing Needle Coke From Coal Tar Distillate - 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. | 12-03-2009 |
20090294327 | Reduced Puffing Needle Coke From Decant Oil - A reduced puffing needle coke is formed from decant oil, which includes a lesser amount of nitrogen within the coke so that carbon articles produced from such coke experience minimal expansion upon heating to graphitization temperatures. | 12-03-2009 |
20100308280 | Reinforced Resin-Derived Carbon Foam - 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. | 12-09-2010 |
20100314790 | Highly Oriented Graphite Product - A graphite article having enhanced directional thermal conductivity is provided. The mesophase portions of a mesophase pitch are aligned with each other to create an oriented mesophase pitch which may be stabilized. The article may subject to further carbonization and graphitization as needed. | 12-16-2010 |
20110020631 | Coated Carbon Foam Article - A carbon foam article useful for, inter alia, composite tooling or other high temperature applications, which includes a carbon foam substrate, an intermediate material on a surface of the carbon foam substrate, and a tool facing material on an outer surface of the article such that the intermediate material is positioned between the tool facing material and the carbon foam substrate. | 01-27-2011 |
20110274136 | Reduced Puffing Needle Coke From Coal Tar - A reduced puffing needle coke is formed, which includes a lesser amount of nitrogen within the coke so that carbon articles produced from such coke experience minimal expansion upon heating to graphitization temperatures. | 11-10-2011 |
20110280274 | Reduced Puffing Needle Coke From Decant Oil - A reduced puffing needle coke is formed from decant oil, which includes a lesser amount of nitrogen within the coke so that carbon articles produced from such coke experience minimal expansion upon heating to graphitization temperatures. | 11-17-2011 |
20110280275 | Reduced Puffing Needle Coke From Coal Tar Distillate - 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. | 11-17-2011 |
20110318566 | Insulated Panel For Mine Safe Rooms - A structural insulated panel for use in a mine safe room, which includes a carbon foam core having a high ratio of compressive strength to density, desirable fire retardant properties, and resistance to environmental stress. | 12-29-2011 |
20120009415 | Carbon Foam Tooling With Durable Skin - 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. | 01-12-2012 |
20120107555 | Composite Tooling - A carbon foam article useful for, inter alia, composite tooling or other high temperature applications, which includes a substrate, wherein the substrate includes at least one material selected from carbon foam, extruded graphite, graphite foam, and isomolded graphite. The tool may also include a skin as a working surface and a filler disposed below the skin. The tool has a surface roughness of no more than about 63 micro-inches. Such a tool may be used to make a composite prototype part. | 05-03-2012 |
20130012744 | Reduced Puffing Needle Coke From Coal Tar Distillate - 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. | 01-10-2013 |
