METHOD FOR FILLING OPEN PORE OF CERAMIC BASE COMPOSITE MATERIAL, AND CERAMIC BASE COMPOSITE MATERIAL

Japanese Patent JP2022089299

A

To provide a method for filling an open pore in the matrix of a ceramic base composite material with a ceramic, even when the open pore formed in the matrix of the ceramic base composite material has a size (for example, width) of several μm or less.SOLUTION: A method for filling an open pore formed in the matrix of a ceramic base composite material including reinforcing fiber in the matrix, with a ceramic to make the matrix, comprises repeating the following steps (A) and (B), in a state with the ceramic base composite material disposed in a liquid material as the raw material of the matrix. (A) Heating the ceramic base composite material to make the liquid material in a film boiling state, which forms a ceramic derived from the liquid material in the open pore. (B) Cooling the ceramic base composite material to a temperature lower than the boiling point of the liquid material.SELECTED DRAWING: Figure 1
