ABSTRACT:
This invention provides a hybrid yarn obtained by combining the filaments of a carbon fiber and a specific inorganic fiber composed substantially of elements Si, Ti or Zr, C and O having a ratio of tensile modulus of the inorganic fiber to tensile modulus of the carbon fiber in the range of from 0.6 to 1.4. Further, this invention provides a unidirectional prepreg obtained by unidirectionally arranging the hybrid yarn prepared from a carbon fiber and a specific inorganic fiber and impregnated with a thermosetting resin, and provides a laminated material obtained by laminating the prepregs.
