PREPREG, AND CARBON FIBER REINFORCED COMPOSITE MATERIAL |
摘要 |
To provide a prepreg and a carbon fiber reinforced composite material that are excellent in adhesion between a matrix resin and carbon fibers and long-term storage stability and also excellent in microcrack resistance due to the increased toughness. The present invention provides a prepreg that includes; agent-coated carbon fibers coated with a sizing agent; and a thermosetting resin composition impregnated into the sizing agent-coated carbon fibers. The sizing agent includes an aliphatic epoxy compound (A) and an aromatic epoxy compound (B1). The sizing agent-coated carbon fibers are in a shape of woven fabric or braid. The thermosetting resin composition includes a thermosetting resin (D), a thermoplastic resin (F), and a latent hardener (G). The sizing agent-coated carbon fibers have an (a)/(b) ratio in a certain range where (a) is the height of a component at a binding energy assigned to CHx, C-C, and C=C and (b) is the height of a component at a binding energy assigned to C-O in a C 1s core spectrum of the surfaces of the sizing agent-coated carbon fibers analyzed by X-ray photoelectron spectroscopy. |
