ABSTRACT:
Fibers for use in forming fiber reinforced ceramic composites may be effectively deagglomerated and/or dispersed in the precursor from which the continuous phase of the composite is to be derived by passing the fibers through a screen with openings that are from two to ten times as wide as the fiber diameter. By using this technique, composites of alumina fibers in a partially stabilized zirconia matrix have been prepared with better fiber orientation and fiber aspect ratio than previously achieved.
