A process for the preparation of a fiber-reinforced ceramic matrix composite comprised of monofilament fibers having a continuous uniform coating of a ceramic matrix material is described comprising the steps of: (a) coating at least one monofilament fiber by drawing the fiber through a filament guide immersed in a slurry comprised of a ceramic matrix material in an amount sufficient to form a continuous uniform coating on the surface of the fiber and an ultraviolet curing agent in an amount sufficient to bind the continuous uniform coating of ceramic matrix material to the fiber upon curing with ultraviolet radiation; (b) rapidly curing the coating before breakup of the coating slurry on the fiber by exposure to ultraviolet radiation; (c) heat treating at least one coated and cured monofilament fiber to decompose the ultraviolet curing agent and sinter the ceramic material to form a compact; and (d) densifying the compact to produce a fiber-reinforced ceramic matrix composite comprised of at least one monofilament fiber having a continuous uniform coating of a ceramic matrix material.
