Abstract: A method for producing a multi-component part (200) of a vehicle includes inserting an air-guiding device (10) having at least one contact portion (40) into a cavity (310) of a tool (300). The method then includes heating a composite part (100) having at least one mating contact portion (140) to a melting point of at least one material of the composite part (100), and heating the contact portion (40) of the air-guiding device (10) to a melting point of at least one material of the contact portion (40). The method further includes inserting the heated composite part (100) into the cavity (310) of the tool (300) and pressing the heated composite part (100) into a geometry of the part while simultaneously forming an integrally bonded connection between the mating contact portion (140) of the composite part (100) and the contact portion (40) of the air-guiding device (10).

Abstract: An underbody panel for a motor vehicle is composed of a lightweight sandwich material and is configured as a single part with at least one continuous folding connection (12) that is arranged between first and second portions of the underbody panel (14). The first and second portions can be folded together via the folding connection (12) and, in the folded state, are substantially parallel to each other to reduce a size of the underbody panel during transport and storage. Additionally, the underbody panel is gap-free when installed on a motor vehicle.
