SURFACE-AIDED MELT INFILTRATION FOR PRODUCING A CERAMIC MATRIX COMPOSITE
A method of melt infiltration for producing a ceramic matrix composite comprises applying a surface slurry onto one or more outer surfaces of an impregnated porous preform. The surface slurry comprises a solvent and particulate solids, and the preform comprises a framework of ceramic fibers loaded with particulate matter. The surface slurry is dried to form a porous layer comprising the particulate solids on the one or more outer surfaces of the impregnated porous preform. After forming the porous layer, an end portion of the impregnated porous preform that includes at least part of the porous layer is immersed in a molten material, and the molten material is infiltrated into the impregnated porous preform from the end portion. The porous layer serves as a wick to transport the molten material over the one or more outer surfaces, thereby enabling melt infiltration of the impregnated porous preform from other portions thereof.
