Abstract

A fiber composite component with a lighting function includes a fiber reinforced unit with at least two fiber layers integrated into a plastics matrix, and an electroluminescent light having a light source arranged between two adjacent fiber layers, the light source including a first insulating layer and a second insulating layer which electrically insulate the light source from the two adjacent fiber layers.

Claims (27)

1. A fiber composite component with a lighting function, the fiber composite component comprising:

a fiber reinforcement comprising at least two fiber layers incorporated into a polymer matrix, and

an electroluminescent lamp having a lighting element disposed between two adjacent fiber layers, wherein:

the lighting element has a first insulation layer and a second insulation layer that electrically isolate the lighting element from the two adjacent fiber layers.

2. The fiber composite component according to claim 1 , wherein:

the first insulation layer is directed to a visible side of the fiber composite component and takes a form of a color layer.

3. The fiber composite component according to claim 2 , wherein:

the second insulation layer faces away from the visible side of the fiber composite component and is formed by a polymer film.

4. The fiber composite component according to claim 3 , wherein the second insulation layer is formed by a PES film bonded to the lighting element by an acrylic adhesive.

5. The fiber composite component according to claim 1 , wherein:

the electroluminescent lamp has a contacting section disposed in an edge region of the fiber composite component.

6. The fiber composite component according to claim 5 , wherein:

a component section of the fiber composite component that surrounds the contacting section is free of reinforcement fibers.

7. The fiber composite component according to claim 1 , wherein:

the lighting element, viewed from a visible side of the fiber composite component, is covered by the polymer matrix and exactly one fiber layer.

8. The fiber composite component according to claim 1 , wherein:

a visible layer of the fiber reinforcement is formed from directed continuous fibers.

9. The fiber composite component according to claim 1 , wherein:

a visible layer of the fiber reinforcement is formed from at least one of carbon fibers, metallized glass fibers or metal fibers.

10. The fiber composite component according to claim 1 , wherein:

the polymer matrix is at least partly transparent.

11. The fiber composite component according to claim 1 , wherein:

the polymer matrix is a thermoset polymer matrix.

12. The fiber composite component according to claim 1 , wherein:

the fiber composite component is an exterior or an interior component of a vehicle.

13. The fiber composite component according to claim 1 , wherein:

the fiber composite component is a structural component of a vehicle body.
