Abstract
Disclosed herein is a method of manufacturing a high-density fiber reinforced ceramic composite material, including the steps of: 1) impregnating a fiber preform material multi-coated with pyrolytic carbon and silicon carbide to form impregnated fiber reinforced plastic composite material; 2)carbonizing the impregnated fiber reinforced plastic composite material to form carbonized fiber composite material; 3) a primary reaction-sintering of the fiber composite material; 4) cooling the primarily reaction-sintered fiber composite material down to room temperature and then impregnating the primarily reaction-sintered fiber composite material with a solution in which a polymer precursor for producing silicon carbide (SiC) is dissolved in a hexane (n-hexane) solvent; and 5) a secondary reaction-sintering of the fiber composite material; and a high-density fiber reinforced ceramic composite material manufactured using the method.
