Process for producing ceramic fiber-reinforced composite material
To provide a process for producing a ceramic fiber-reinforced composite material, which suppresses the deterioration of an interface layer, improves mechanistic properties and has excellent durability even under a high temperature, even ceramic fibers formed of silicon carbide fibers are used, without complicating the production steps. To obtain a ceramic fiber-reinforced composite material, by melt-infiltrating a composite material substrate obtained by forming ceramic fibers, formed of silicon carbide fibers and having an amorphous structure, into a composite with a matrix formed of an inorganic substance, with an alloy having a composition that is constituted by a disilicide of at least one or more transition metal among transition metals selected from scandium, yttrium, titanium, zirconium, hafnium, and tantalum, and silicon as the remainder, and having the silicon content ratio of 66.7 at % or more and less than 90.0 at %.
