Claim 17:
18. A shroud segment made of ceramic matrix composite materials for use with a gas turbine engine, the shroud segment comprising:
a shroud wall that extends circumferentially partway around a central axis of the gas turbine engine,
a first attachment flange that extends radially outward away from the shroud wall, and
a second attachment flange spaced apart axially from the first attachment flange that extends radially outward away from the shroud wall,
wherein the first attachment flange of the blade track segment includes a first axially aft-facing surface that faces the second attachment flange and extends radially outward and axially forward away from the shroud wall at a first angle relative to a first radial plane that extends radially and circumferentially relative to the central axis of the gas turbine engine, the second attachment flange of the blade track segment includes a first axially forward-facing surface that faces the first attachment flange and extends radially outward and axially aft away from the shroud wall at a second angle relative to a second radial plane parallel to the first radial plane,
wherein one of the first attachment flange and the second attachment flange of the blade track segment includes a second axially facing surface opposite one of the first axially aft-facing surface of the first attachment flange and the first axially forward-facing surface of the second attachment flange that extends radially outward and axially away from the shroud wall at a third angle relative to a third radial plane that is parallel to the first and second radial planes and the third angle is different from the first angle and the second angle.
