Abstract

A fiber-reinforced plastic component includes a three-dimensional component plastic member and at least one reinforcement fiber rod. The three-dimensional component plastic member determines at least parts of a shape of the plastic component. The three-dimensional component plastic member has at least one void which is open to at least one side and in which the at least one reinforcement fiber rod is placed.

First claim

What is claimed is:

1. A fiber-reinforced plastic component comprising:
a three-dimensional component plastic member which determines at least parts of a shape of the plastic component; and
at least one reinforcement fiber rod, wherein
the three-dimensional component plastic member has at least one void which is open to at least one side and in which the at least one reinforcement fiber rod is placed,
the at least one void is a plurality of voids which form a framework structure which are provided in the component plastic member, and
the at least one reinforcement fiber rod is placed in each of the plurality of voids.

2. The fiber-reinforced plastic component as claimed in claim 1 , wherein the component plastic member is produced in a generative or additive manufacturing method.

3. The fiber-reinforced plastic component as claimed in claim 2 , wherein the plurality of voids are configured by a tub-shaped or groove-shaped depression.

4. The fiber-reinforced plastic component as claimed in claim 1 , wherein said fiber-reinforced plastic component in addition to the component plastic member has at least one mating member which is configured for closing the open side of the plurality of voids.

5. The fiber-reinforced plastic component as claimed in claim 4 , wherein the at least one mating member, at least in portions in the region of the plurality of voids, has a shape that is complementary to the component plastic member.

6. The fiber-reinforced plastic component as claimed in claim 5 , wherein the at least one reinforcement fiber rod is pressed into the plurality of voids via the mating member.

7. The fiber-reinforced plastic component as claimed in claim 6 , wherein the at least one reinforcement fiber rod is connected in a materially integral manner to the component plastic member.

8. The fiber-reinforced plastic component as claimed in claim 7 , wherein the plurality of voids extend in a parallel direction and are provided in the component plastic member.

9. The fiber-reinforced plastic component as claimed in claim 1 , wherein two of the plurality of voids are arranged adjacent to one another and one of said two voids is open to at least another side that is opposite to the at least one side.

10. A fiber-reinforced plastic component comprising:
a three-dimensional component plastic member which determines at least parts of a shape of the plastic component; and
at least one reinforcement fiber rod, wherein
the three-dimensional component plastic member has at least one void which is open to at least one side and in which the at least one reinforcement fiber rod is placed,
the at least one void has an elongated tub-shape, and
the at least one void includes two voids arranged adjacent to one another and one of the two voids is open to at least another side that is opposite to the at least one side.

11. A method for producing a fiber-reinforced plastic component, comprising:
providing a three-dimensional component plastic member which determines at least parts of a shape of the plastic component; and
providing at least one reinforcement fiber rod, wherein
the three-dimensional component plastic member has a plurality of voids which are open to at least one side and in which the at least one reinforcement fiber rod is placed,
the plurality of voids form a framework structure and are provided in the component plastic member, and
the at least one reinforcement fiber rod is placed in each of the plurality of voids.

12. The method for producing a fiber-reinforced plastic component as claimed in claim 11 , wherein the at least one reinforcement fiber rod is fastened to the component plastic member, the at least one reinforcement fiber rod is heated to a melting temperature of the component plastic member, and the at least one heated reinforcement fiber rod is placed into the plurality of voids of the component plastic member such that the at least one reinforcement fiber rod is welded to the component plastic member.

13. The method for producing a fiber-reinforced plastic component as claimed in 12 , wherein the at least one reinforcement fiber rod is placed into the plurality of voids in a robotically guided manner.
