Abstract
A fiber-reinforced plastics component includes a component plastics body, which defines at least parts of a plastics component, and at least one fiber-reinforced rod. The component plastics body is formed at least partially from plastics foam and at least partially surrounds the at least one fiber-reinforced rod in positively locking fashion.
Claims6
A fiber-reinforced plastic component of a motor vehicle, comprising:
- a plastic component body;
- and
- at least one fiber-reinforced rod, wherein
- the plastic component body is formed at least partly from plastic foam and at least partly form-fittingly surrounds the at least one fiber-reinforced rod,
- the at least one fiber-reinforced rod includes a carbon fiber rod with a plastic matrix,
- the plastic foam and the plastic matrix are composed of a same material, the at least one fiber-reinforced rod has been subjected to in-mold coating by the plastic foam,
- the plastic foam has a noise absorption functionality,
- multiple fiber-reinforced rods are mutually arranged in a lattice structure,
- the plastic component body additionally includes an injection-molded structure, wherein the injection-molded structure is subjected to in-mold coating by the plastic foam, wherein the injection-molded structure has a lattice structure that corresponds to the lattice structure of the multiple fiber-reinforced rods such that the injection-molded structure and the multiple fiber-reinforced rods overlap, wherein the injection-molded structure is a carrier structure applied to the multiple fiber-reinforced rods, and wherein the multiple fiber-reinforced rods are secured on the carrier structure of the injection-molded structure, and
- the injection-molded structure includes binding structures, wherein the binding structures secure the fiber-reinforced plastic component to a vehicle frame of the motor vehicle.
