Method for fabrication of a ceramic matrix composite sandwich structure
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.
