PURPOSE:A mixture of SiO2 and carbon or the like is heated in the presence of a Y compound and the resultant gas is brought into contact with active carbon fiber under prescribed conditions to produce easy-to-handle fibers for reinforcement, because they are obtained in a collective form of silicon carbide whiskers. CONSTITUTION:A mixture of SiO2 or its precursor and carbon or its precursor is heated in the presence of a Y compound in a non-oxidative atmosphere to generate a gas. The resultant gas is brought into contact with active carbon or organic fibers containing Si components in a nonoxidative atmosphere at 1,200- 1,700 deg.C to give the objective easy-to-handle collective fibers which is used in combination with other substances as a reinforced composite. |
