Abstract
An improved method for fabricating ceramic composites, particularly single crystal alumina fiber and yttrium-aluminum garnet (YAG) matrix composites. The method of this invention comprises the steps of (a) coating the fiber with a metal which is stable under oxidizing conditions, such as Pd, (b) coating the metal-coated fiber with a fugitive phase, such as Mo, (c) incorporating the coated fiber into a matrix material, (d) densifying the fiber-matrix into a composite and (e) heat treating the composite under oxidizing conditions to remove the fugitive phase.
