Abstract

A fiber composite component, comprising a basic element which comprises fibers embedded in a matrix material. A production method for a fiber composite component. A structural component, comprising a support element and the reinforcement element and also a production method for a structural component. The fiber composite component comprises a base element, comprising fibers embedded in a matrix material, and a reinforcement element, comprising fibers embedded in a matrix material wherein the base element and the reinforcement element are interconnected, a hole leads through the base element and the reinforcement element, wherein fibers of the base element that are adjacent to the hole are severed, and fibers of the reinforcement element that are adjacent to the hole are continuous.

First claim

The invention claimed is:

1. A fiber composite component, comprising:
a base element comprising fibers embedded in a first matrix material;
a reinforcement element comprising fibers embedded in a second matrix material, wherein the base element and the reinforcement element are interconnected, wherein the reinforcement element is mountain shaped; and
a first hole through the base element and a second hole through the reinforcement element,
wherein the fibers of the base element that are adjacent to the first hole are severed, and the fibers of the reinforcement element that are adjacent to the second hole are not severed such that the fibers are continuous and flex around the second hole,
wherein the fiber composite component is part of a component of a wind power installation.

2. The fiber composite component as claimed in claim 1 , wherein the fibers of the base element are disposed within the first matrix material as one or more of:
woven fabrics,
cross-laid structures,
multi-axis cross-laid structures, embroideries, non-woven material,
mats, and
braided fabrics,
and the fibers of the reinforcement element are fiber bundles.

3. The fiber composite component as claimed in claim 2 , wherein the fibers of the reinforcement element are rovings.

4. The fiber composite component as claimed in claim 1 , wherein at least one of: the fibers of the base element or the reinforcement element include one or more of:
organic fibers,
inorganic fibers, or
natural fibers.

5. The fiber composite component as claimed in claim 1 , wherein at least one of: the first matrix material of the base element or the second matrix material of the reinforcement element includes a plastic material.

6. The fiber composite component as claimed in claim 5 , wherein the plastic material is a thermoplastics material or a thermosetting plastics material.

7. The fiber composite component as claimed in claim 5 , wherein the plastic material includes one or more of: cement, concrete, metal, ceramics, or carbon.

8. The fiber composite component as claimed in claim 1 , wherein at least one of:
the base element and the reinforcement element are interconnected in a materially integral or form-fitting manner; or the base element and the reinforcement element are interconnected by way of the fibers embedded in the first matrix material of the base element and in the second matrix material of the reinforcement element.

9. A wind power installation comprising:
a tower;
a nacelle;
a rotor; and
the component that includes the fiber composite component as claimed in claim 1 .

10. A method for producing the fiber composite component as claimed in claim 1 , the method comprising:
producing the base element such that the fibers adjacent to the first hole are severed,
producing the reinforcement element such that the fibers adjacent to the second hole are continuous, and
mutually arranging and interconnecting the base element and the reinforcement element such that the first hole and the second hole are interconnected.

11. The method for producing the fiber composite component as claimed in claim 10 , wherein interconnecting the base element and the reinforcement element comprises using an adhesive that is composed of one of the first or second matrix materials of the base element or the reinforcement element.

12. The method for producing the fiber composite component as claimed in claim 11 , wherein a placeholder is used when producing the second hole.

13. The fiber composite component as claimed in claim 1 , wherein the reinforcement element at an end of the second hole that faces away from the base element has a bearing face for receiving a connection element, the bearing face being planar in a manner orthogonal to a passage direction of the first and second holes.

14. A structural component for a wind turbine, comprising:
a reinforcement element comprising fibers embedded in a matrix material,
wherein the reinforcement element has sloped side portions forming a mountainous shape,
wherein a hole extends through the reinforcement element, and
wherein the fibers of the reinforcement element are not severed such that the fibers adjacent to the hole of the reinforcement element are continuous and flex around the hole,
a support element coupled to the reinforcement element, and
a hole extending through the support element, wherein the hole extending through the support element is aligned with the hole extending through the reinforcement element.

15. A method for producing the reinforcement element as claimed in claim 6 , the method comprising:
producing the reinforcement element from the fibers and from the matrix material,
wherein producing the reinforcement element includes forming the hole, wherein all of the fibers that are adjacent to the hole remain continuous.

16. A method for producing the structural component as claimed in claim 14 , the method comprising:
producing the support element,
forming the hole in the support element,
producing the reinforcement element having the hole, and
mutually arranging and interconnecting the support element and the reinforcement element in such a manner that the hole of the support element and the hole of the reinforcement element are interconnected.
