The present invention relates to a composite pipe, a composite roller, a composite pipe manufacturing method, and a composite roller manufacturing method using the composite pipe and, more specifically, to a composite pipe, a composite roller, a composite pipe manufacturing method, and a composite roller manufacturing method using the composite pipe capable of reducing a capacity of a motor for rotating and controlling the composite roller by remarkably reducing weight increases of the composite pipe and composite roller in comparison with an existing metallic roller. A composite pipe according to an embodiment of the present invention includes a cylindrical inner pipe made of a reinforcing fiber with impregnated thermo-hardening resin; a middle supporting unit covering the surface of the inner pipe in the circumferential direction and composed of a plurality of core members; and an outer pipe covering the surface of the middle supporting unit in the circumferential direction and made of a reinforcing fiber with impregnated thermo-hardening resin. |
