1. A prepreg obtained by impregnating carbon fiber with a matrix resin comprising a mixture of a thermoplastic resin, a thermosetting resin, and a curing agent,
wherein the prepreg is characterized in that:
the thermoplastic resin is a phenoxy resin;
the thermosetting resin is a urethane acrylate resin;
the thermoplastic resin and the thermosetting resin are compounded in a mass ratio of 15:85-35:65 (thermoplastic resin/thermosetting resin);
the carbon fiber is a carbon cloth or a unidirectional fiber; and
the curing agent is formed so as to include a first peroxide, a second peroxide, and a third peroxide having different one-minute half-life temperatures, the one-minute half-life temperature of the second peroxide being 20-60° C. higher than that of the first peroxide, and the one-minute half-life temperature of the third peroxide being 10-40° C. higher than that of the second peroxide.
