Fiber-reinforced intermetallic and ceramic matrix composites are promising materials for high temperature structural applications in oxidizing environments. The limitations of c-axis single crystal Al{sub 2}O{sub 3} fiber have led to the development of alternative single crystal oxide fibers such as MgAl{sub 2}O{sub 4}, YAG and oxide/oxide eutectic fibers, such as Al{sub 2}O{sub 3}/ZrO{sub 2}(Y{sub 2}O{sub 3}) and Y{sub 3}Al{sub 5}O{sub 12}/Al{sub 2}O{sub 3} eutectic fiber. The directionally solidified oxide-oxide eutectic fiber offers an attractive combination of mechanical property and chemical stability and, therefore, it has a promising potential for a variety of high temperature structural applications in oxidizing environment.
