Manufacturing method of ceramic base composite member and mold device for manufacturing ceramic base composite member

摘要

To provide a method of easily and inexpensively producing a ceramic-based composite material member having excellent dimensional accuracy and shape accuracy, and a mold device suitable for its enforcement.SOLUTION: Provided is a method for producing a ceramic-based composite material member comprising: a slurry preparation step of preparing an oxide-based ceramic powder slurry; an impregnation step of forming an impregnated sheet by impregnating an inorganic fiber sheet with the slurry; a press step of arranging the impregnated sheet between a first mold and a second mold facing each other, sandwiching a spacer at a position where the impregnated sheet is not positioned therebetween, tightening the first mold and the second mold by a first fastener in such a manner that the first mold and the second mold are made close along the facing direction, and applying pressure to the impregnated sheet; a drying step of sandwiching a spacer with a thickness different from that of the spacer, instead of the spacer, at a position where the impregnated sheet is not positioned between the first mold and the second mold, tightening the first mold and the second mold by the first fastener in such a manner that the first mold and the second mold are made close along the facing direction, and heating and drying the impregnated sheet; and a firing step of firing the sheet after drying.SELECTED DRAWING: Figure 1
