Title:
MANUFACTURING METHOD FOR CERAMIC-BASED COMPOSITE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2018/105670
Kind Code:
A1
Abstract:
Provided is a ceramic-based composite material manufacturing method which is unlikely to result in strength deterioration and with which it is possible to shorten manufacturing time. This manufacturing method is for a ceramic-based composite material having a woven fabric that has multiple fiber bundles and having a matrix that is disposed in the gaps between the fiber bundles, the manufacturing method comprising: a base body formation step for forming a base body by calcining the woven fabric impregnated with a polymer that is a precursor to the matrix; and a densification step for further impregnating the base body with a polymer and calcining same. The densification step comprises: a second impregnation step for further impregnating the base body with a polymer so as to form an impregnated base body; a drying step for drying the impregnated base body so as to form a dried base body; a steam treatment step for leaving the dried base body under saturation water vapor pressure so as to form a treated base body; and a calcination step for calcining the treated base body.
