SACRIFICIAL FIBERS FOR COOLING AIR FLOW IN CERAMIC MATRIX COMPOSITES, METHODS OF MANUFACTURE AND ARTICLES COMPRISING THE SAME
Disclosed herein is a composite comprising a ceramic matrix composite comprising a ceramic matrix and ceramic fibers; and one or more sacrificial fibers woven into the ceramic matrix composite; where the sacrificial fibers are operative to undergo oxidation or melting upon being subjected to an elevated temperature; and wherein the sacrificial fibers leave cooling holes in the composite preform upon being subjected to oxidation or melting.
