A drive shaft includes a first shaft member made of metal, a tubular member made of CFRP, and a first exterior sleeve. The first shaft member is capable of being attached on one end side thereof to a first constant velocity joint, and has a first serrated part on which serrations are formed on another end side thereof. The tubular member is formed with a first fitting part fitted externally over the first serrated part. The first exterior sleeve covers the first fitting part by being disposed to extend over outer circumferential surfaces of the first shaft member and the tubular member. A film provided with a bonding assistance region and an adhesive are interposed between the outer circumferential surface of the tubular member and the inner circumferential surface of the first exterior sleeve.

The invention relates to a method for producing a composite component (12). At least one shaft (2) and at least one sintered part (1), preferably in the form of a rotor or a cam, are assembled into the composite component. In order to assemble the composite component, at least the following steps are carried out: —introducing the shaft (2) into a continuous bore (3) of the sintered part (1) and —calibrating the sintered part (1) at least by means of a calibrating die (4), furthermore preferably with the simultaneous application of an axial force onto the sintered part (1) by means of at least one upper punch (5) and at least one lower punch (7), wherein the shaft (2) can be found in the bore (3) of the sintered part (1) at least temporarily during the calibration process. The invention further relates to a composite component (12).
