    Thumbnail
    Inventor(s):
    Manuel Koucouthakis, Douglas J. Steinke, Alexander Mukasyan, Jeremiah D. E. White
    Patent Number:
    US 9321692 B2
    Description:

    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 …

    Rapid synthesis of silicon carbide-carbon composites
    Description
    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.
