▎ 摘　　要

NOVELTY - Carbon fiber is attached with graphene oxide. USE - The carbon fiber is useful in a resin composition for a thermally conductive sheet for an electronic component, and a fiber-reinforced resin sheet (all claimed), and for fiber reinforced plastics and heat radiating sheets. The resin composition is useful for motor vehicle components, such as modules, including instrument panel, door beam, undercover, lamp housing, pedal housing, radiator support, spare tire cover and front end, notebook personal computer, mobile telephone, electrical/electronic components, such as digital still camera, plasma display, telephone, a facsimile, videotape recorder, a copy machine, a television, a microwave oven, an audio equipment, toiletry article, a laser disc, a refrigerator, and a home and office electricity product components, such as an air-conditioner. The fiber-reinforced resin sheet is useful for external reinforcement portions of containers, such as a pipe and a pressure vessel. ADVANTAGE - The carbon fiber has excellent interfacial shear strength, high mechanical strength, thermal conductivity, surface external appearance, dispersibility, electroconductivity and adhesiveness, avoids fear of rupture of graphene oxide, and improves surface elasticity rate and reinforcement effect. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a resin composition comprising the carbon fiber and a resin; (2) a fiber-reinforced resin sheet comprising the resin composition, where the carbon fibers are oriented in one direction; and (3) a method for producing the carbon fiber, involving bringing graphene oxide into contact with the carbon fiber.
