<p>A ceramic casting shell mold having a pre-selected shape is described. It includes alternate, repeating layers of a ceramic coating material and a ceramic stucco, defining a total thickness of the shell mold; and a ceramic-based mat of reinforcing material disposed in the alternate, repeating layers of coating material and stucco. The reinforcing material for the mat is usually made from a ceramic material, and includes fibers having a bi-directional orientation. A method for making a ceramic casting shell mold is also described, as well as articles cast from such a mold, e.g., superalloy articles.</p> |
