    • A fiber-reinforced ceramic composite material reinforced by particle dispersion with improved fracture toughness comprised of a mullite matrix, and fibers and same or different kind of ceramic fine particles both dispersed within the mullite matrix is produced by a method comprising: dispersing mullite particles forming a matrix in a solution dissolving an organometallic macromolecular substance to prepare an impregnating solution, continuously passing fibers through said impregnating solution to uniformly impregnate the fibers with said impregnating solution, laminating said fibers to provide a laminated body, converting the organometallic macromolecular substance within said laminated body into a nonmeltable state, and performing sintering (or press sintering) of said laminated body in an inert gas and/or nitrogen gas. By press sintering K.sub.Ic of 10 MN/m.sup.3/2 or more is achieved.
