Abstract

Wood-plastic hybrid component for use in a motor vehicle having a multi-component structure including a wood subsection, at least one water-impermeable plastic coating, arranged directly on the wood subsection for protecting the wood subsection, and a plastic subsection. The water-impermeable plastic coating is at least partially directly adjacent to the plastic subsection.

First claim

What is claimed is:

1. A vehicle component comprising:
a multi-component structure including (i) a plastic subsection in the form of a hollow body, (ii) a wood subsection surrounding at least a portion of the plastic subsection and forming sidewalls of the hollow body, and (ii)(iii) at least one water-impermeable plastic coating arranged directly on the wood subsection for protecting the wood subsection,
wherein the water-impermeable plastic coating is at least partially directly adjacent to the plastic subsection.

2. The vehicle component as claimed in claim 1 , wherein the wood subsection is at least partially directly connected to the plastic subsection.

3. The vehicle component as claimed in claim 1 , wherein the water-impermeable plastic coating is connected to the plastic subsection by material bonding and in a water-tight manner.

4. The vehicle component as claimed in claim 1 , wherein the wood-plastic hybrid component has at least one single-layered section, in which the plastic subsection has no direct connection to the wood subsection or the water-impermeable plastic coating.

5. The vehicle component as claimed in claim 1 , wherein the wood-plastic hybrid component has at least one two-layered section including only the wood subsection and the water-impermeable plastic coating that is arranged directly on the wood subsection, wherein neither the wood subsection nor the water-impermeable plastic coating have a direct connection to the plastic subsection.

6. The vehicle component as claimed in claim 1 , wherein the wood-plastic hybrid component has at least one three-layered section including the plastic subsection, the wood subsection and the water-impermeable plastic coating that are arranged at least partially directly on one another.

7. The vehicle component as claimed in claim 1 , wherein the wood-plastic hybrid component has at least one three-layered section including the wood subsection and a water-impermeable plastic coating on two opposite surfaces of the wood subsection.

8. The vehicle component as claimed in claim 1 , wherein the wood-plastic hybrid component has at least one four-layered section including the wood subsection, a water-impermeable plastic coating on two opposite surfaces of the wood subsection, and the plastic subsection on at least one side of the wood subsection.

9. The vehicle component as claimed in claim 1 , wherein the plastic subsection is a fiber-reinforced plastic.

10. The vehicle component as claimed in claim 1 , wherein the plastic subsection is an injection molded plastic layer.

11. The vehicle component as claimed in claim 1 ,
wherein the water-impermeable plastic coating and/or the plastic subsection are/is a thermoplastic and/or thermosetting plastic and/or a biopolymer, and
wherein the water-impermeable plastic coating and/or the plastic subsection are composed of the same material.

12. The vehicle component as claimed in claim 1 , wherein the wood subsection is a layer or part of a single- or multi-part or single- or multi-layer wood semifinished product, and wherein the wood subsection is formed from one of the following types of wood:
beech,
oak,
spruce,
fir, and
bamboo.

13. The vehicle component as claimed in claim 1 , wherein the wood subsection (i) is coated on at least one side with the water-impermeable plastic coating, (ii) is coated over an entire surface of the at least one side with the water-impermeable plastic coating, or (iii) is coated over an entire surface of more than one side with the water-impermeable plastic coating.

14. The vehicle component as claimed in claim 1 , wherein a layer thickness of the water-impermeable plastic coating is at most one-third of the layer thickness of the wood subsection and/or of the plastic subsection.

15. The vehicle component as claimed in claim 1 , wherein the water-impermeable plastic coating is a plastic film or a plastic varnish.

16. A motor vehicle having the vehicle component as claimed in claim 1 .

17. The vehicle component as claimed in claim 1 , wherein the hollow body includes opposing sides, wherein each side includes two protruding flanges, and
wherein for each side of the opposing sides, the wood subsection is positioned between the two protruding flanges.

18. The vehicle component as claimed in claim 17 , wherein a top-mounted flange of the two protruding flanges extends further outward from the wood subsection than a bottom-mounted flange of the two protruding flanges.

19. The vehicle component as claimed in claim 1 , wherein the hollow body comprises an open-ended box.

20. The vehicle component as claimed in claim 1 , wherein the wood subsection is not positioned within the hollow body.
