Definitions
- the invention relates to a structural or chassis part of a motor vehicle, wherein the structural or chassis part consists of a composite material with an outer metallic layer, a middle plastic or plastic foam layer and an outer fiber-reinforced plastic layer.
- Safety requirements are ensured by structural or chassis parts.
- Structural parts in the context of the present invention are therefore, for example, parts of the subfloor, floor panels,
- the said structural parts have in common that they are not part of the visible outer skin of the motor vehicle and serve mainly because of their supporting function for receiving and / or forwarding forces acting on the motor vehicle.

- Composite material serves on the one hand to protect the
- thermoplastic or thermosetting, middle layer for example, from moisture, on the other hand, as an outer skin but also as an indicator of a possible overloading of the structural part or chassis part. For example, cracks or bulges in the metallic layer may indicate overloading.
- the consistent use of the composite material in the structural or chassis parts according to the invention enables a further, significant reduction in weight Motor vehicles.
- the structure of the structural or chassis parts also allows a permanent use in the motor vehicle without property losses occur because, for example, the sensitive fiber-reinforced plastic layer can be protected by the other layers.

- thermoplastic are based Plastic layers on a polyamide and / or polyethylene.
- both thermoplastics can be processed very well; on the other hand, they have advantageous properties with respect to their formability when hot.
- Polyamide is generally more stable in temperature compared to polyethylene and can also be used in
- Thermosets are thermally stable and can be used, for example, in areas where higher temperatures, in particular, may occur for a short time.
