Beschreibung
Zusammenfassung:	The invention relates to a composite component comprising at least a first component and a second component which are joined together in a joint region, wherein the joint region has a plastic deformation region by means of which the first component and the second component are held in the joint region by cold deformation with a holding force directed towards one another. In the plastic deformation region the first component has a recess which is at least partially filled with deformed material from the second component. The deformed material forms a protuberance which projects from the second component, protrudes into the recess and forms a contact region between the first component and the second component with an undercut. The undercut counteracts a detachment of the components in the event of a force being applied to the joint region. The deformation region is cold-formed by clinching. The main material of the first component having the recess has a lower yield strength than the main material of the second component, which at least partially fills the recess with deformed material. Furthermore, at least in the joint region the first component and the second component are in the form of metal sheets or metal-sheet-like parts, and a main sheet thickness of the second component is greater than a main sheet thickness of the first component.
