The present invention provides a process for preparing an interply-hybridized laminated material which comprises impregnating carbon fiber and inorganic fiber composed of Si, Ti or Zr, C and O with thermosetting resin to form respective prepregs and laminating the prepregs, wherein (i) the ratio of the tensile modulus of said carbon fiber to that of said inorganic fiber is 0.6/1 to 1.4/1, or (ii) the lamination structure is symmetrical along the lamination thickness with regard to the central planar area, or (iii) one of the outermost two layers is a carbon fiber-containing prepreg and the other is an inorganic fiber-containing prepreg.
