A seal (100; 150; 200; 300) includes a ceramic matrix composite ply (109; 159) having woven ceramic-based fibers (110) in a ceramic-based matrix (112). The ceramic matrix composite ply (109; 159) has at least one bend (108) formed about a bend axis (B) and defines at least one rounded portion. A sealed assembly and a method of making a seal (100; 200; 300) are also disclosed. Preferably at least one bend defines a tube shape, the woven ceramic based fibers include a first set of fibers oriented in a first direction and a second set of fibers oriented in a second direction and woven with the first set of fibers, and the first set of fibers is angled with respect to the bend axis at an angle between about 0 and 60 degrees, or the relative volume fractions of the first set of fibers and the second set of fibers is between about 5% and 60%. T he sealed component is part of a gas turbine engine.
