Abstract: A lining for a compressor case in use with a gas turbine engine compressor is provided. The compressor includes a compressor casing, which is generally comprised of a first and second half. Inside the casing is a plurality of vanes attached to a plurality of vane bands. The vane bands are affixed to the interior of the compressor casing. A lining, comprising a carbon fiber reinforced-type material is applied to the interior of the compressor casing over the vane bands. The lining allows a minimal clearance to be between the lining and wheel blade tips spinning within the compressor casing. The carbon fiber in the lining allows the lining to withstand a high number of temperature cycles due to the use of the compressor and the gas turbine engine.
