摘要： A seal assembly for a gas turbine engine according to an example of the present disclosure includes, among other things, a seal housing that extends about an axis. The seal housing defines an annular groove. A contacting-type seal is at least partially received in the annular groove. The seal includes a seal member and a seal carrier that extends about and mechanically attaches to an outer diameter of the seal member. The seal member defines an annular seal face that is moveable along the axis to abut against a seal seat. The seal member includes a first material, and the seal carrier includes a second, different material.
