DETAILED DESCRIPTION OF THE INVENTION

[0044] FIG. 1a shows a wood-plastic hybrid component 2 for use in a motor vehicle 100 without a water-impermeable plastic coating 10 for protecting a wood subsection 8, in a perspective view.

[0045] As can be seen from FIG. 1a, a plurality of wood semifinished products 8′ is arranged on an outer side of the plastic part 6′, said semifinished products being connected by material bonding to the plastic part 6′ in the present case.

[0046] FIG. 1b shows a wood-plastic hybrid component 2 as per FIG. 1a in a sectional illustration according to a section along section line I-I.

[0047] As can be seen from FIG. 1b, a wood subsection 8 of the wood semifinished product 8′ is in each case connected directly to the plastic subsection 6 of the plastic part 6′ on both sides of the plastic part 6′.

[0048] FIG. 2a shows a wood-plastic hybrid component 2 according to aspects of the invention for use in a motor vehicle 100, having a water-impermeable plastic coating 10 for protecting a wood subsection 8 in a perspective view, in accordance with a first exemplary embodiment.

[0049] As can be seen from FIG. 2a, a plurality of wood semifinished products 8′ is arranged on an outer side of the plastic part 6′, said semifinished products being arranged on the plastic part 6′ and each being completely coated with a water-impermeable plastic coating 10. In this case, the water-impermeable plastic coating 10 is also at least partially adjacent to the plastic part 6′ or the plastic subsection 6.

[0050] FIG. 2b shows a wood-plastic hybrid component according to aspects of the invention as per FIG. 2a in a sectional illustration according to a section along section line II-II.

[0051] As can be seen from FIG. 2b, the wood-plastic hybrid component has a multi-component structure 4, comprising a wood subsection 8, at least one water-impermeable plastic coating 10, arranged directly on the wood subsection 8, for protecting the wood subsection 8, and a plastic subsection 6, wherein the water-impermeable plastic coating 10 is at least partially directly adjacent to the plastic subsection 6. Here, the wood subsection 8 of the wood semifinished product 8′ is coated over its entire surface with a water-impermeable plastic coating 10 on both sides of the plastic part 6′ and is connected to the plastic subsection 6 via the water-impermeable plastic coating 10.

[0052] FIG. 3a shows a wood-plastic hybrid component 2 according to aspects of the invention in a plan view, in accordance with another exemplary embodiment.

[0053] As can be seen from FIG. 3a, the wood semifinished product 8′ is at least partially surrounded by the plastic part 6′, which is connected thereto by material bonding.

[0055] As can be seen from FIG. 3b, the wood semifinished product 8′ is firmly incorporated into the plastic part 6′. On an outer side 12, the wood semifinished product 8′ is furthermore coated with a water-impermeable plastic coating 10 in order to protect the wood semifinished product 8′ or the wood subsection 8 from the influence of moisture. On the other hand, there is no water-impermeable plastic coating 10 on an inner side 14, on which the wood-plastic hybrid component 2 is not exposed to moisture.

[0056] FIG. 4 shows individual steps of the method according to aspects of the invention for producing a wood-plastic hybrid component. In this case, the method according to aspects of the invention comprises the steps of applying 200 a water-impermeable plastic coating 10 to a wood subsection 8 of a wood semifinished product 8′, inserting 300 the wood semifinished product 8′ into a shaping tool, closing 400 the shaping tool and carrying out a shaping process, and also opening 500 the shaping tool and removing the wood-plastic hybrid component 2.
