Abstract: PURPOSE:To manufacture an inorganic fiber material for composite reinforcement having superior wettability, by allowing polytitanocarbosilane or polyzirconocarbosilane to an inorganic fiber material and subjecting the above material to heat treatments in an oxygen-containing gaseous atmosphere and then in a nonoxidizing atmosphere. CONSTITUTION:Polytitanocarbosilane or polyzirconocarbosilane is allowed to adhere to an inorganic fiber material such as C, Al2O3, etc., forming a central layer, which is heated in an oxygen-containing gaseous atmosphere so as to be made infusible. Subsequently, the resulting fusible inorganic fiber material is heat-treated in a nonoxidizing atmosphere. By the above treatments, a surface layer which consists of an amorphous substance essentially composed of Si, M (M means Ti or Zr), C, and O, an aggregate essentially containing
