ABSTRACT:
A specific sizing agent comprising as the main component an adduct of mono- or poly-cyclic phenol with alkylene oxide is applied in a specified amount to the surface of a high-strength and high-elasticity carbon fiber or a precursor fiber thereof and then dried to prepare a reinforcing carbon fiber according to the present invention, which is then preformed into a fiber arrangement, impregnated with a precursor of matrix carbon, and carbonized to produce a high-strength and high-elasticity carbon-carbon composite material.
