ABSTRACT:
A method of forming a breakage resistant, erosion resistant ceramic liner for a part comprising the steps of, forming a liner of a ceramic material containing pores; filling the pores with a pre-ceramic polymer resin; and, firing the liner saturated with a pre-ceramic polymer resin at a temperature and for a time which converts the resin into a ceramic within the pores. The liner can be mechanically attached, adhesively bonded or, a metal part can be cast onto the liner by placing the liner within the metal casting mold for the part as a sidewall or integral element thereof. The invention also includes method for producing parts and liners of fiber reinforced ceramic matrix composite by a resin transfer molding process or the like wherein fiber preforms are saturated with liquid pre-ceramic polymer resin. The preforms are then polymerized in a mold, the part removed from the mold, and then fired to transform the polymer to ceramic. The process can also be employed to form hollow parts such as manifolds.
