Abstract
A glass-impregnated, fiber-reinforced ceramic comprises a ceramic matrix having open voids, inorganic fibers embedded in the ceramic matrix in a regular or irregular orientation, and a glass matrix filling up the open voids in the ceramic matrix. The glass-impregnated, fiber-reinforced ceramic is manufactured by a manufacturing method comprising the steps of forming a fiber-reinforced ceramic comprising the ceramic matrix having open voids, and inorganic fibers embedded in the ceramic matrix, impregnating the fiber-reinforced ceramic with a glass precursor solution containing a glass precursor to stop up the open voids of the ceramic matrix with the glass precursor solution, and subjecting the fiber-reinforced ceramic impregnated with the solution to a heat treatment.
