Abstract

A coated composite component includes, in this order, a composite component, a fluorine-containing film and/or a fluorine-containing woven fabric, knitted fabric or crocheted fabric, and a tear-off fabric. A method for producing a coated composite component including, in this order, a composite component, a fluorine-containing film and/or a fluorine-containing woven fabric, knitted fabric or crocheted fabric, and a tear-off fabric.

First claim

What is claimed is:

1. A coated composite component comprising,
an uncured composite component;
a fluorine-containing film and/or a fluorine-containing fabric disposed on the composite component; and
a tear-off fabric disposed on the composite component and covering all edges of the fluorine-containing film and/or fabric;
wherein a surface area of the fluorine containing film and/or fabric is smaller than a surface area of the tear-off fabric and smaller than a surface area of the composite component, and
wherein the tear-off fabric only partially covers the surface area of the fluorine-containing film and/or fabric.

2. The coated composite component according to claim 1 , wherein the uncured composite component is a carbon-fiber-reinforced plastics material.

3. The coated composite component according to claim 2 , wherein the carbon-fiber-reinforced plastics material is in the form of a prepreg.

4. The coated composite component according to claim 2 , wherein the plastics material is an epoxy or vinyl ester resin.

5. The coated composite component according to claim 1 , wherein the uncured composite component is cured.

6. The coated composite component according to claim 1 , wherein the tear-off fabric and/or the fluorine-containing film and/or fabric is/are able to withstand temperatures of 120° C. or more.

7. The coated composite component according to claim 1 , wherein the fluorine-containing film and/or fabric is disposed on an area of the composite component that is to be bonded to another component.

8. The coated composite component according to claim 7 , wherein the area of the composite component that is to be bonded to another component is easily cleaned or does not require additional cleaning.

9. The coated composite component according to claim 1 , wherein the tear-off fabric does not comprise any fluorine-containing material.

10. The coated composite component according to claim 9 , wherein the tear-off fabric comprises separating agents based on silicon or hydrocarbon in order to ensure removal of the tear-off fabric from the composite component.

11. The coated composite component according to claim 1 , wherein the fluorine-containing film and/or fabric is porous or comprises holes.

12. The coated composite component according to claim 1 , wherein the fluorine-containing film fabric is covered at least in part by a metal sheet.

13. The coated composite component according to claim 1 , wherein the fluorine-containing fabric comprises a woven fabric, a knitted fabric, or a crocheted fabric.

14. A method for producing a coated composite component, comprising the steps as follows:
i) providing an uncured composite component;
ii) applying a fluorine-containing film and/or a fluorine containing fabric on the composite component; and
iii) applying a tear-off fabric on the composite component such that the tear-off fabric covers all edges of the fluorine-containing film and/or fabric;
wherein a surface area of the fluorine containing film and/or fabric is smaller than a surface area of the tear-off fabric and smaller than a surface area of the composite component, and
wherein the tear-off fabric only partially covers the surface area of the fluorine-containing film and/or fabric.

15. The method according to claim 14 , wherein the uncured composite component is a carbon-fiber reinforced plastics material, and the method comprises an additional step of iv) curing the coated raw composite component after applying the tear-off fabric.

16. The method according to claim 15 , wherein the tear-off fabric and/or the fluorine-containing film and/or fabric is/are able to withstand temperatures of 120° C. or more during the curing step.

17. The method according to claim 14 , wherein the fluorine-containing film and/or fabric is disposed on an area of the raw composite component that is to be bonded to another component.

18. The method according to claim 14 , wherein the fluorine-containing film and/or fabric is porous or comprises holes.

19. The method according to claim 14 , wherein the fluorine-containing film and/or fabric is covered at least in part by a metal sheet.

20. The method according to claim 14 , wherein the fluorine-containing fabric comprises a woven fabric, a knitted fabric, or a crocheted fabric.
