Claim 17:
18. A method of damping for a gas turbine engine comprising:
positioning a gas turbine engine component adjacent to at least one metallic damper, wherein:
the at least one damper includes a first contact surface; and
the gas turbine engine component includes a main body extending between a gaspath surface and a second contact surface, the first and second contact surfaces are spaced apart along the interface in a cold assembly state, and the main body is established by a composite including fibers arranged to establish a plurality of cooling passages aligned with the interface;

damping the gas turbine engine component in response to contact between the first and second contact surfaces along the interface; and
conveying cooling flow through the cooling passages to provide cooling augmentation to a portion of the at least one damper in contact with the gas turbine engine component along the interface.
