METHOD OF MELT INFILTRATION UTILIZING A NON-WETTING COATING FOR PRODUCING A CERAMIC MATRIX COMPOSITE
A method of melt infiltration for producing a ceramic matrix composite (108) comprises applying a non-wetting coating (102) onto one or more outer surfaces of a porous fibre preform (104). The non-wetting coating comprises a non-wetting material with which molten silicon has a contact angle (¸c) of at least about 45 degrees. After applying the non-wetting coating, an uncoated portion (104b) of the porous fibre preform is immersed into a molten material (106) comprising silicon, and the molten material is infiltrated into the porous fibre preform through the uncoated portion. The non-wetting coating serves as a barrier to inhibit or prevent the molten material from penetrating the one or more outer surfaces. After infiltration of the molten material into the porous fibre preform, the molten material is cooled to form a ceramic matrix composite (108), and the non-wetting coating is removed.
