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.
Claims20
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, 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.

A method comprising:
- distributing thermally conducting particles between plies in a preform, wherein distributing the thermally conducting particles include a distributing first amount of particles at a first region generating a first amount of heat and distributing a second amount of particles at a second region generating a second amount of heat less than the first amount of heat so that the heat generated in the first region is redistributed to the second region;
- dispersing a ceramic precursor through the preform;
- and
- reacting the precursor to form a ceramic matrix.
