ABSTRACT
Fibers or whiskers having high strengths and Young's moduli are required for useful reinforcement of ceramics. In addition, chemical compatability between the fibers and matrix are required. Also, for elevated temperature applications, the fibers must be acceptably thermally stable at the application temperature. Low fiber density is obviously an advantage. Finally, cost (or, in the case of experimental fibers, projected cost based on commercial production) must not be prohibitive for intended applications.
