Title:
METHOD FOR PRODUCING SILICON-IMPREGNATED CERAMIC COMPOSITE MATERIAL, METHOD FOR PRODUCING FRICTION PLATE, AND METHOD FOR PRODUCING BRAKE DISC
Document Type and Number:
WIPO Patent Application WO/2019/176896
Kind Code:
A1
Abstract:
A method for producing a silicon-impregnated ceramic composite material comprising: a firing step in which a molded article comprising ceramic fibers and a ceramic precursor is heated, and a ceramic composite material is obtained by converting the ceramic precursor into a ceramic; and an impregnating step in which a metallic silicon is impregnated into the ceramic composite material. The molded article is disposed inside of a container that houses the solid metallic silicon with a support tool therebetween. After the firing step is performed at a first temperature, which is the temperature within the container that is a temperature less than the melting point of the metallic silicon and at which the ceramic precursor is converted into a ceramic, the impregnating step is performed where, by raising the temperature to a second temperature, which is a temperature greater than or equal to the melting point of the metallic silicon, the molten metallic silicon is impregnated into the ceramic composite material through the support tool, which comprises a porous material.
