Abstract
A ceramic fiber blanket is inserted into a mold, and ceramic fiber slurry, preferably made with refractory ceramic fibers, binders, and water, is deposited on the blanket. Vacuum pressure is created under the blanket to pull the fibers of the slurry toward the fibers of the blanket to entangle them together. The slurry and blanket is then dried to form a rigid yet surface compliant ceramic fiber composite product with superior thermal insulating and acoustic dampening properties.
