Abstract
A manufacturing method for a ceramic matrix composite, having a woven fabric that has multiple fiber bundles and having a matrix that is disposed in the gaps between the fiber bundles, includes: a green body formation step for forming a green body by sintering the woven fabric infiltrated with a polymer that is a precursor to the matrix; and a densification step for further infiltrating the green body with a polymer and sintering same. The densification step includes: a second infiltration step for further infiltrating the green body with a polymer so as to form an infiltrated green body; a drying step for drying the infiltrated green body so as to form a dried green body; a steam treatment step for leaving the dried green body under saturation water vapor pressure so as to form a treated green body; and a sintering step for sintering the treated green body.
