Abstract
A rotary member is a carbon fiber-reinforced molded article in which a carbon fiber is embedded in a matrix resin, and is a rotary member that rotates integrally with a rotary body of an electric motor or a generator. The rotary member includes a helical layer in which a composite carbon fiber is oriented at an inclination angle in a range of 40° to 80° with respect to an axial direction of the rotary member, and a hoop layer in which the composite carbon fiber is oriented in a direction substantially orthogonal to the axial direction of the rotary member. The composite carbon fiber includes a structure that is provided on a surface of the carbon fiber, includes a plurality of carbon nanotubes having a bent shape and including a bent portion, and forms a network structure including a contact portion in which the carbon nanotubes are in direct contact with each other, and a sizing agent that cross-links the carbon nanotubes in direct contact with each other.
