Zusammenfassung:	An example gas turbine engine shroud (28) includes a first annular ceramic wall (30) having an inner side (38) for resisting high temperature turbine engine gases and an outer side (40) with a plurality of radial slots (36). A second annular metallic wall (32) is positioned radially outwardly of and enclosing the first annular ceramic wall and has a plurality of tabs (34) in communication with the slot of the first annular ceramic wall. The tabs of the second annular metallic wall and slots of the first annular ceramic wall are in communication such that the first annular ceramic wall and second annular metallic wall are affixed together.
