METHOD FOR PRODUCING CARBON FIBER-REINFORCED SILICON CARBIDE COMPOSITE MATERIAL, AND CARBON FIBER REINFORCED SILICON CARBIDE COMPOSITE MATERIAL
To provide a method for producing a carbon fiber-reinforced silicon carbide composite material, the method exhibiting excellent productivity, reducing a processing cost, and capable of producing the carbon fiber-reinforced silicon carbide composite material that has high impact strength, and to provide the carbon fiber-reinforced silicon carbide composite material.SOLUTION: A carbon fiber-reinforced silicon carbide composite material is produced by conducting the steps of: impregnating carbon fibers with a thermosetting resin to obtain a sheet-molding compound; aging the sheet-molding compound by exposing it to an atmosphere of at least 130°C or less and higher than the boiling point of a solvent component under atmospheric pressure if the thermosetting resin contains a solvent component, or to an atmosphere of 75°C or more to 130°C or less if the thermosetting resin does not contain a solvent component; forming the sheet-molding compound obtained after aging to obtain a carbon fiber-reinforced plastic; sintering the carbon fiber-reinforced plastic to obtain a carbon fiber-reinforced carbon composite material; and melt-impregnating the carbon fiber-reinforced carbon composite material with a metallic Si.SELECTED DRAWING: None
