  • Method for fabrication of a ceramic matrix composite sandwich structure
    Patent number: 10974995
    Abstract: A method for fabricating a ceramic matrix composite structure. A core having an ordered structure is fabricated of a preceramic polymer and pyrolyzed. Facesheets, either uncured or cured, are placed on the core (with a bonding layer of preceramic polymer resin if the facesheets are cured) and the assembly is cured and pyrolyzed. The pyrolyzed assembly is re-infiltrated with preceramic polymer resin and re-pyrolyzed. The cycle of re-infiltration and re-pyrolyzation is repeated until the mass gain per cycle stabilizes.

  • Thermal barrier coating with temperature-following layer
    Patent number: 10851711
    Abstract: A temperature-following layer may be applied to a surface of components within an internal combustion engine. The temperature-following layer follows the temperature swing of adjacent gases (for example, in a combustion chamber). The temperature-following layer may be applied directly to a substrate, or the temperature-following layer may be an outer layer of a multi-layer thermal barrier coating. The multi-layer thermal barrier coating may include, for example, an insulating layer, a sealing layer bonded to the insulating layer, and a porous temperature-following layer disposed on the sealing layer. The sealing layer is substantially non-permeable and configured to seal against the insulating layer.
