Abstract:
A method of manufacturing a glass-impregnated, fiber-reinforced ceramic, comprising:forming a three-dimensional inorganic fiber structure including a plurality of inorganic fibers and a space among the inorganic fibers, the plurality of inorganic fibers being arranged in the inorganic fiber structure in a three-dimensional woven fabric with respect to each other; producing a fiber-reinforced ceramic by filling the space with a ceramic matrix, the fiber-reinforced ceramic including the ceramic matrix having voids opening to the outside and the inorganic fiber structure embedded in the ceramic matrix; impregnating the fiber-reinforced ceramic with glass precursor solution containing glass precursor to fill the voids of the ceramic matrix with the glass precursor solution; heat treating the fiber-reinforced ceramic impregnated with the glass precursor solution; and repeating the impregnating of the fiber-reinforced ceramic with the glass precursor solution and the heat treating of the fiber-reinforced ceramic impregnated with the glass precursor solution a plurality of times.
