Abstract
An improved method for producing a fiber-reinforced ceramic composite having a monazite interface between the reinforcing fiber and the ceramic matrix, which comprises the steps of coating each filament in a continuous fiber tow with an aqueous sol that forms monazite after high temperature heat treatment, heat treating the thus-coated fiber tow to provide a coated tow having a layer of monazite thereon, embedding the fiber in a suitable ceramic matrix, and densifying the composite.
