Patent number: 9321692Abstract: Production of pore-free carbon/carbon-silicon carbide composite materials with mechanical properties making them suitable for use in such applications as the production of aircraft landing system brake components including brake discs. The method includes: providing a porous carbon-carbon composite preform; surrounding the porous carbon-carbon composite preform with silicon powder to form an intermediate construct; applying a uniaxial load to the construct; applying direct electrical current to an assembly containing the loaded construct of porous carbon-carbon preform surrounded by silicon powder, thereby melting the silicon powder and infiltrating the pores of the carbon-carbon preform with liquid silicon; and initiating a combustion-type reaction between the silicon and carbon in the preform, thereby forming silicon carbide in the preform.Type: GrantFiled: July 31, 2009Date of Patent: April 26, 2016Assignees: Honeywell International Inc., The University of Notre Dame du LacInventors: Manuel Koucouthakis, Douglas J. Steinke, Alexander Mukasyan, Jeremiah D. E. White

Patent number: 7588179Abstract: Resin-impregnated carbon fiber composites containing metal inserts. Carbon fibers or a carbon fiber preform are bonded to a metal structural member. Once the carbon fiber-metal bond is established, the fiber-metal assembly or hybrid preform is impregnated with resin, to form an article in which bonding between the metal structural member and the composite remainder of the article is greatly enhanced. In a process embodiment, a metal insert, e.g. a steel insert, is provided in contact with particulate carbide-forming metal, e.g. titanium, and with carbon fiber segments. Then an electric current is passed through the carbide-forming metal particles and carbon fibers to heat them to a temperature above the melting point of the carbide-forming metal. This initiates an exothermic reaction, which forms liquid phase metal carbide. Subsequently the liquid phase metal carbide is cooled and solidified, thereby bonding the carbon fiber segments to the metal insert.Type: GrantFiled: March 30, 2007Date of Patent: September 15, 2009Assignee: Honeywell International Inc.Inventors: Allen H. Simpson, Mark L. La Forest, Alexander Mukasyan, Douglas J. Steinke
