Claim 12:
13. A gas turbine engine component comprising:
a component body to be positioned in a turbine section of an engine having a rotational axis, the component body having a radially outer face defining a sealing surface, and there being at least one brush seal having bristles extending from a mount location radially outward of said sealing surface to contact said sealing surface, said bristles which extend radially inwardly to seal between a first higher pressure chamber and a second lower pressure chamber, and the bristles defining an angle with the sealing surface having an axial component extending in a direction toward the higher pressure chamber, and the angle is less than 90° on a side of the brush seal on second lower pressure side of the bristles;
wherein the component body is formed of ceramic matrix components; and
the bristles having a first end in contact with said sealing surface and a second end mounted in a housing to define the mount location.
