Claims20
A ceramic matrix composite (CMC) material comprising rare earth phosphate ceramic fibers embedded in a ceramic matrix.
A method for manufacturing a ceramic matrix composite (CMC) material comprising the steps of:
- weaving ceramic fibers into a mat structure, wherein the ceramic fibers comprise rare earth phosphate ceramic fibers;
- infiltrating the ceramic fiber mat structure with a ceramic matrix precursor slurry to form a slurry-infiltrated ceramic fiber mat structure;
- and
- heating the slurry-infiltrated ceramic fiber mat structure to form the CMC material.
A gas turbine engine comprising a gas turbine engine component, wherein the gas turbine engine component is formed at least in part of a ceramic matrix composite (CMC) material, and wherein the CMC material comprises rare earth phosphate ceramic fibers embedded in a ceramic matrix.
