The present invention relates to a complex roller used for a variety of industrial fields such printing, paper manufacturing, and film and liquid manufacturing. According to the present invention, the complex roller comprises: a metal sleeve; a roll core combined by being inserted into an inner surface of the metal sleeve; and a pair of end members individually combined and fixated with both ends of the roll core. In order to minimize and lighten a thickness of the roll core, at least one reinforcing disk inserted into an inner surface of the roll core and fixated is included; thus the thickness of the carbon fiber reinforced plastic, which is the material of the roll core, is able to be 30-50% of the thickness of the existing complex roller. As such, the roller is able to be lightweight and low costs, and secures a reinforcement corresponding to an existing complex roller. |
