Composite tubular woven seal for an inner compressor discharge case

An inner compressor discharge case for a gas turbine, comprising:

• a cylindrical barrel formed of upper and lower halves joined to one another at margins thereof along a horizontal midline to form a pair of diametrically opposed joints along opposite sides of the barrel, each of the margins of one of said halves having a groove extending generally parallel to an axis of the cylindrical barrel, each of the margins of another of said halves having a sealing surface extending generally parallel to the axis of the cylindrical barrel;
• a compliant seal disposed in each of said grooves including a seal body formed of multiple layers of different materials for compliantly and sealingly engaging against the margin of said another of said halves upon securing said halves to one another;
• each of said grooves having a generally rectilinear cross-section, said compliant seal in an uncompressed condition having a generally circular cross-section, said seal substantially compliantly filling said groove upon securement of said case halves to one another;
• said materials of said seal body comprising a woven metal core, a fiber, a metallic foil and a protective layer.
