Patent number: 9193113Abstract: A pitch densification apparatus may be used to form a carbon-carbon composite material. The apparatus may be used to compress a carbon fiber material, and, thereafter, pitch densify the carbon fiber material. The compression and pitch densification of the carbon fiber material may be carried out within the same mold cavity of the pitch densification apparatus. In one example, an apparatus may comprise a mold defining a mold cavity that is configured to receive a material to be densified. The mold cavity is configured to be adjusted from a first volume to a second volume less than the first volume to compress the material in the mold cavity. The example apparatus may further comprise a gas source configured to apply a gas pressure in the mold cavity to force pitch into the material in the mold cavity to densify the material, and a vacuum source configured to create a vacuum pressure in the mold cavity at least prior to the application of the gas pressure.Type: GrantFiled: July 21, 2014Date of Patent: November 24, 2015Assignee: Honeywell International Inc.Inventors: Mark L. La Forest, Mark C. James, Roger L. Klinedinst, Neil Murdie, David M. Wright

Patent number: 8721954Abstract: In some examples, a method for densifying a material via pitch comprises inserting the material to be densified into a mold, wherein the mold is part of an apparatus. The apparatus may include a ram configured to apply a ram pressure sufficient to force a pitch into the mold to densify the material, a gas source configured to apply a gas pressure sufficient to force the pitch into the mold to densify the material, and a vacuum source operable to create a vacuum pressure in the mold at least prior to application of either the ram pressure or the gas pressure. The method may further comprise densifying the material in the mold via pitch using a selectable one of the ram, the gas source, the ram and the vacuum source, or the gas source and the vacuum source.Type: GrantFiled: March 13, 2013Date of Patent: May 13, 2014Assignee: Honeywell International Inc.Inventors: Mark L.

Patent number: 8448685Abstract: An apparatus for bonding a first carbon composite to a second carbon composite through a reactant layer includes a housing, and a pair of conductive press plates electrically isolated from the housing. The press plates are adapted to position the two parts to be bonded with a reactant layer therebetween. The press plates are subjected to an electrical potential and a clamping force, sufficient to initiate a combustion reaction that creates a molten ceramic to bond together the carbon-carbon composites.Type: GrantFiled: March 2, 2011Date of Patent: May 28, 2013Assignees: Honeywell International Inc., University of Notre Dame du LacInventors: Allen H. Simpson, Slawomir T. Fryska, Mark L. La Forest, Roger L. Klinedinst, Alexander Mukasyan, Charles D. D'Amico

Publication number: 20120104659Abstract: A pitch densification apparatus may be used to form a carbon-carbon composite material. In some examples, the apparatus is configured to pitch densify a material using one or more of a plurality of different pitch densification techniques. For example, the apparatus may densify a material with a selectable one of the resin transfer molding cycle, the vacuum-assisted resin transfer molding cycle, and/or the vacuum pressure infiltration cycle. The apparatus may respond to initial or changing properties of a material to be densified. In some additional examples, the apparatus includes a mold configured to receive a preform and a portion of solid pitch separate from the preform. The apparatus may include a heating source thermally coupled to the mold that is configured to heat the solid pitch above a melting temperature of the solid pitch. The apparatus may melt the pitch without external pitch melting equipment.Type: ApplicationFiled: November 2, 2010Publication date: May 3, 2012Applicant: HONEYWELL INTERNATIONAL INC.Inventors: Mark L.
