摘要: A carbon fiber coated with a sizing agent is provided. This exhibits excellent adhesion to matrix resin, ensures stability of composite physical properties prepreg even after long-term storage, and in high-order processability. process for producing the agent, prepreg, reinforced material are also which comprises (A) an aliphatic epoxy compound (B) aromatic that contains (B1) as essential component, characterized (a)/(b) ratio 0.50 0.90 wherein (a) height (cps) peak at binding energy 284.6eV assignable CHx, C-C C=C C1S core spectrum determined by subjecting surface X-ray photoelectron spectroscopy using AlKa1.2 source emission angel 15°, (b) 286.1eV C-O therein.
