ABSTRACT:
A method of forming ceramic fiber and metal composite structures is disclosed. The method is particularly useful in forming such structures having a complex shape. Fibers are coated with an investment grade sticky wax as a fugitive organic binder. Aluminium oxide coated with a sticky wax binder have been found to have greater flexibility than the fibers alone or fibers coated with other binders. The coated fibers are then laid up into a preform of the desired shape. The preform is elevated to a moderate temperature prior to pressure compaction. The preform may be combined with other preforms to form a more complex shape. The preform is then installed in a casting mold and elevated to a temperature sufficient to remove the sticky wax binder. Molten metal is then introduced into the mold where it fills the voids created by the removal of the sticky wax. Subsequent to cooling, the fiber and metal composite material is removed from the casting mold.
