A densified ceramic matrix composite (CMC) material densified CMC exhibits superior strength and toughness, relative to prior CMCs The material can be made by a process that includes impregnating a set of ceramic fibers with a non-fibrous ceramic material, resulting in a precursor matrix, stabilizing the precursor matrix, resulting in a stabilized matrix, and densifying the stabilized matrix using a frequency assisted sintering technology (FAST) process, resulting in the densified CMC material.
