Abstract

A fiber composite component includes a composite including cured matrix material and a fiber material embedded therein. At least one partial area of the fiber composite component is provided with at least one thread, which undulates as it extends along a surface area of the composite, so that sections of the thread alternately run inside of the composite and outside of the composite. An adhesive arrangement for such fiber composite components is also disclosed. Finally, methods for manufacturing such a fiber composite component or for manufacturing such an adhesive arrangement are disclosed.

First claim

The invention claimed is:

1. A method for manufacturing a fiber composite component comprising:
a) providing a fiber material with a separating foil on a surface area;
b) introducing at least one thread into at least one partial area of the fiber material, such that the thread undulates as the thread extends along the surface area of the fiber material, such that sections of the thread alternately run inside of the fiber material and outside of the fiber material;
c) infiltrating the fiber material with a curable matrix material;
d) curing the matrix material; and
e) peeling away the separating foil from the fiber material, so that the thread loops are free of the matrix material.

2. The method of claim 1 , wherein the at least one thread includes a plurality of several fibers.

3. The method of claim 1 , wherein the thread sections running outside of the composite each have a length of at least 0.2 mm.

4. The method of claim 1 , wherein the thread sections running outside of the composite each have a length of at least 0.4 mm.

5. The method of claim 1 , wherein at least 20% of the at least one thread runs inside of the composite and/or at least 30% of the at least one thread runs outside of the composite.

6. The method of claim 1 , wherein at least 30% of the at least one thread runs inside of the composite and/or at least 40% of the at least one thread runs outside of the composite.

7. The method of claim 1 , wherein the thread sections running outside of the composite in the surface area of a partial area are provided with a density of at least 5,000/qm.

8. The method of claim 1 , wherein the thread sections running outside of the composite in the surface area of a partial area are provided with a density of at least 10,000/qm.
