Abstract
A method of making a ceramic matrix composite includes infiltrating a fiber preform comprising silicon carbide fibers with a slurry comprising a liquid, silicon carbide particles, carbon particles, and silicon particles to form a slurry-infiltrated fiber preform. The slurry-infiltrated fiber preform is infiltrated with a molten material comprising silicon. Prior to or during the infiltration with the molten material, the silicon particles are melted. The molten material is cooled, and a ceramic matrix composite including a ceramic matrix reinforced with the silicon carbide fibers is formed, where the ceramic matrix is substantially devoid of dry slurry defects.
