In a processing method for a ceramic-based composite material in which the ceramic-based composite material is molded by layering sheets obtained by impregnating reinforced fibers with a slurry containing ceramic powder and calcining the sheets after curing, the processing method includes layering the sheets in a layering direction to form a laminate, and covering the laminate with a vacuum bag and evacuating an inside of the vacuum bag to mold a cured laminate. In molding the cured laminate, a slurry-removing material configured to absorb excess slurry is disposed with respect to the laminate, and a degassing circuit member provided on at least one side of the laminate and configured to discharge air bubbles generated inside the laminate is disposed with respect to the laminate.

A silicon resin is applied to the outer wall of the transition piece of a gas turbine subjected to the thermal barrier coating by caulking the cooling holes provided in the inner wall by a resin. Then, the transition piece is heated in an atmosphere furnace in order to burn or decompose the resin. A part of the silicon resin applied to the outer wall of the transition piece is decomposed or evaporated by the heating to be discharged to the atmosphere in the furnace, but a part of the silicon resin remains and protects the outer wall.
