Patent number: 8105511Abstract: A method of manufacturing a carbon-carbon brake disc uses a restraint fixture (12) that includes a preform retention region configured to limit contracting forces applied against a preform (10) in the preform retention region when the restraint fixture (12) thermally contracts. In one embodiment, the restraint fixture (12) comprises a band (12) having a first surface defining the preform retention region and a first expansion portion (26, 28, 29) adapted to deform upon application of a force to the band (12).Type: GrantFiled: June 17, 2008Date of Patent: January 31, 2012Assignee: Honeywell International Inc.Inventors: Allen H. Simpson, Mark L. La Forest, Slawomir T. Fryska, Barry P. Soos

Patent number: 7700014Abstract: Method of manufacturing dense carbon-carbon composite material by: infiltrating a fibrous preform with pitch to form pitch-infiltrated preform; carbonizing the pitch-infiltrated preform; injecting resin or pitch into the preform in a mold; oxygen stabilizing the filled preform and carbonizing and heat-treating the oxygen-stabilized impregnated preform; and subjecting the preform to a single final cycle of chemical vapor deposition. This process reduces densification time as compared to comparable conventional carbon-carbon composite manufacturing procedures.Type: GrantFiled: April 13, 2006Date of Patent: April 20, 2010Assignee: Honeywell International Inc.Inventors: Allen H. Simpson, Slawomir T. Fryska, Mark L. La Forest, Barry P. Soos

Publication number: 20100084075Abstract: This invention relates to an improved carbon-carbon composite material and method of preparation. The carbon-carbon composite material comprises a plurality of carbon fiber substrates that have been joined or consolidated. In the present invention, the carbon fibers are stressed during the preparation of the composite material. The invention comprises adding a low-melting point pitch to the carbon fiber substrates and heat treating the carbon fiber substrates. The fibers tend to shrink more than the pitch during heat-treatment which produces stress in the fibers. This invention enhances the strength of the composite material and improves reliability.Type: ApplicationFiled: October 13, 2006Publication date: April 8, 2010Inventors: Anthony J. Rutten, Slawomir T. Fryska, Mark L. LaForest, Allen H. Simpson, Barry P. Soos

Patent number: 7686904Abstract: This invention generally pertains to self propagating high temperature synthesis or combustion synthesis as a way of bonding materials. The present invention provides methods and an apparatus for bonding, preferably carbon-carbon composite materials, by combustion synthesis. Generally, the invention involves providing at least two carbon-carbon composite parts to be bonded and interspersing a combustion synthesis material in between the parts with each part in contact with the combustion synthesis material. The combustion synthesis material is then ignited, which initiates the combustion synthesis reaction. Typically, a ceramic material is formed which immediately freezes, bonding the parts together.Type: GrantFiled: October 20, 2006Date of Patent: March 30, 2010Assignee: Honeywell International Inc.Inventors: Slawomir T. Fryska, Mark C. James, Mark L. LaForest, Allen H. Simpson, Barry P. Soos

Patent number: 7632435Abstract: Method of carbonizing pitch-infiltrated fibrous annular preform by: infiltrating the preform with pitch; placing the pitch-infiltrated preform in a constraint fixture having an ejector base plate, an inner wall, an outer wall, and a top press plate; selecting the relative sizes of the preform and the constraint fixture so that a layer of inert friable material may be situated between the preform and walls of the constraint fixture; placing inert friable material (e.g., activated carbon) between the preform and the top, bottom, and walls of the constraint fixture; and subjecting the pitch-infiltrated fibrous preform to carbonization in the constraint fixture. The activated carbon or other inert friable material adsorbs pitch molecules that escape the preform during carbonization, which reduces problems with foaming.Type: GrantFiled: May 18, 2006Date of Patent: December 15, 2009Assignee: Honeywell International Inc.Inventors: Allen H. Simpson, Slawomir T. Fryska, Mark L. La Forest, Barry P. Soos

Patent number: 7438839Abstract: Method for manufacturing a carbonized carbon-carbon composite preform, by: mixing (a) chopped carbon fiber, chopped stabilized pitch fiber, or chopped oxidized polyacrylonitrile (PAN) fiber, (b) thermoplastic pitch binder powder, and (c) activated carbon powder to form a mixture of 15-60 parts by weight of chopped carbon fiber or chopped stabilized pitch fiber or chopped oxidized PAN, 28-83 parts by weight of thermoplastic pitch binder powder, and 1-12 parts by weight of activated carbon powder; depositing this mixture into a mold; pressing/heating the materials in the mold to form a preform by compaction; removing the compacted preform from the mold; and carbonizing the compacted preform. The preform is preferably configured in the form of an aircraft landing system brake disc.Type: GrantFiled: October 1, 2004Date of Patent: October 21, 2008Assignee: Honeywell International Inc.Inventors: Allen H. Simpson, Slawomir T. Fryska, Mark L. La Forest, Barry P. Soos

Patent number: 7252499Abstract: Molding apparatus for rapid transfer of molten resin or pitch in an infiltration molding process. The apparatus includes e.g. an extruder (4) for melting and conveying a resin or pitch and a mold (10) arranged so that resin or pitch is conveyed to a mold insert cavity (19) within the mold. The mold insert contains an internal protrusion such as a locating ring (25) for positioning a porous body (1, 18) within the mold insert cavity in a position that brings about unidirectional flow of the molten resin or pitch through the porous body. Also, rapid resin or pitch infiltration molding process that includes injecting a high melting point, high viscosity, molten resin or pitch into the mold to effect a unidirectional impregnation of a heated preform via a pressure gradient in the mold.Type: GrantFiled: July 11, 2005Date of Patent: August 7, 2007Assignee: Honeywell International Inc.Inventors: Mark L. LaForest, Christopher S. Wahlers, Barry P. Soos

The apparatus includes e.g. an extruder (4) for melting and conveying a resin or pitch and a mold (10) arranged so that resin or pitch is conveyed to a mold insert cavity (19) within the mold. The mold insert contains an internal protrusion such as an outside diameter ring (20) for effecting a pressure gradient and flow of the resin or pitch from one side (ID) of the mold insert cavity toward an opposite side (OD) of the mold insert cavity. The mold insert also contains an internal protrusion such as a locating ring (25) for positioning a porous body (1, 18) within the mold insert cavity in a position that brings about unidirectional flow of the molten resin or pitch through the porous body.Type: ApplicationFiled: December 11, 2002Publication date: June 17, 2004Inventors: Mark L.
