Abstract
Disclosed herein is a ceramic matrix composite comprising a preform comprising a plurality of plies; a ceramic matrix encompassing the plies and distributed through the plies; and thermally conducting particles distributed through the ceramic matrix. Disclosed herein is a method comprising distributing thermally conducting particles between plies in a preform; infiltrating chemical vapors of a ceramic precursor into the plies; and reacting the ceramic precursor to form a matrix.
Claims19
A gas turbine engine comprising:
- a hot section component comprising:
- a preform comprising a plurality of plies;
- a ceramic matrix encompassing the plies and distributed through the plies;
- and
- thermally conducting particles distributed through the ceramic matrix, wherein a first package of particles having a first thermal conductivity is distributed in a first region and a second package of particles having a second thermal conductivity is distributed in a second region, wherein the first thermal conductivity is greater than the second thermal conductivity and heat generated in the first region is distributed by the thermally conducting particles to the second region.
