International Classification:

C04B 37/00
US Classification:

156 8911, 156 8916, 156 8925
Abstract:

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.

US Patent:

20060197244, Sep 7, 2006
Filed:

Mar 7, 2005
Appl. No.:

11/073907
Inventors:

Allen Simpson - Buchanan MI, US
Mark La Forest - Granger IN, US
Slawomir Fryska - Granger IN, US
Roger Klinedinst - North Liberty IN, US
Robert De Ferbrache - Elkhart IN, US
International Classification:

C01B 31/00
US Classification:

264029700, 264328400, 264101000, 425129100
Abstract:

A resin transfer molding (RTM) apparatus () that includes: an extruder (); at least two mold cavities () contained within a mold () in the apparatus, arranged so that resin can be extruded from the extruder () into the mold; a nozzle () for delivering resin from the extruder () into the mold; runners () in the body of the mold to deliver resin from the nozzle () to a mold cavity () within the mold; a venting area () contiguous to each mold cavity to permit gases to escape from the mold cavity () when the mold cavity is infiltrated with resin; and a press () to force the mold () closed during at least resin injection. An advantageous feature of the present invention is that the mold may be configured to accept a part () that is characterized by variations in length, width, and/or thickness, such as a wheel beam key. Also, an RTM process. The process includes: placing a porous preform, e.g., a wheel beam key preform, that is characterized by variations in length, width, and/or thickness into a mold held in a press; injecting a molten resin or pitch into the mold, wherein an extruder is used for injecting the resin; allowing the resin to cool below the melting point; and removing the impregnated preform from the mold. This process is especially adapted for processing fibrous preforms, carbon fiber preforms, nonwoven preforms, random fiber preforms with binder, and foam preforms.

US Patent:

20120104641, May 3, 2012
Filed:

Nov 2, 2010
Appl. No.:

12/938201
Inventors:

Mark L. La Forest - Granger IN, US
Roger L. Klinedinst - North Liberty IN, US
David M. Wright - Springfield MA, US
Assignee:

HONEYWELL INTERNATIONAL INC. - Morristown NJ
International Classification:

C01B 31/04
C01B 31/00
B28B 21/36
US Classification:

264 295, 425504
Abstract:

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.
