ABSTRACT:
There is provided a ceramic fiber casting core used in making cast metal parts comprised of a ceramic fiber structure. The casting core may further comprise a support tube in structural supporting relation to the ceramic fiber structure. There is also provided a method to manufacture the ceramic fiber casting core that comprises mixing ceramic fibers and a binder in a mix tank. Pouring the resultant mixed slurry into a vacuum forming tank. Inserting a perforated mandrel into the vacuum forming tank. Forming a vacuum inside the mandrel resulting in vacuum depositing of the ceramic fiber on the mandrel. Removing the ceramic fiber casting core and mandrel from the vacuum forming tank. Removing the mandrel, and then drying and curing the ceramic fiber structure. When necessary, locating a support member in structural supporting relation to the ceramic fiber structure. Machining the unfinished casting core to a desired outside dimensions.
