Abstract
CARBON FIBERS IN CERAMIC CORES FOR INVESTMENT CASTING A method of producing a ceramic core for investment casting is provided. The method includes injecting a slurry into a disposable die. The slurry includes ceramic particles, a binder, and carbon fibers. The method also includes a first heating to eliminate the disposable die, leaving a cured ceramic core comprising the ceramic particles, binder, and carbon fibers. [Figure 1]
