Abstract

A method for producing a fiber composite component assembly having at least first and second plate-shaped composite structures made from synthetic resin embedded fibers, the at least first and second fiber composite components having a plurality of partial regions not containing synthetic resin is described. The method includes positioning the at least first and second fiber composite components, the partial regions having been brought to flush conformity with each other, bonding the at least first and second positioned fiber composite components by the adhesive layer arranged in between, placing mechanical reinforcement means through the partial regions, infusing the dry partial regions with synthetic resin, and curing the synthetic resin placed in the partial regions.

First claim

The invention claimed is:

1. A method for producing a fiber composite component assembly having at least first and second plate-shaped composite structures made from synthetic resin embedded fibers, the at least first and second fiber composite components having a plurality of partial regions not containing synthetic resin in an initial state, the plurality of partial regions extending from a top surface to a bottom surface of the respective first and second fiber composite components, the method comprising:
positioning the at least first and second fiber composite components, the partial regions having been brought to flush conformity with each other,
bonding the at least first and second positioned fiber composite components by an adhesive layer arranged in between,
placing mechanical reinforcement means through the partial regions,
infusing the plurality of partial regions not containing synthetic resin in the initial state with synthetic resin, and
curing the synthetic resin placed in the plurality of partial regions not containing synthetic resin in the initial state.

2. The method of claim 1 , wherein each of the plurality of partial regions not containing synthetic resin in the initial state is enclosed by a cured region of the fiber composite component.

3. The method of claim 1 , wherein each of the plurality of partial regions is essentially rectangular or oval to round in shape.

4. The method of claim 1 , wherein the mechanical reinforcement means are configured as pins to form a pin connection.

5. The method of claim 1 , wherein the mechanical reinforcement means are configured as threads to form a sewn connection.

6. The method of claim 1 , wherein the plurality of partial regions not containing synthetic resin in the initial state, are produced by inserting a filler during the production of the fiber composite components from fibers and synthetic resin.

7. A method for producing a fiber composite component assembly having at least first and second plate-shaped composite structures made from synthetic resin embedded fibers, the at least first and second fiber composite components having a plurality of partial regions not containing synthetic resin in an initial state, the method comprising:
positioning the at least first and second fiber composite components, the plurality of partial regions not containing synthetic resin having been brought to flush conformity with each other,
bonding the at least first and second positioned fiber composite components by an adhesive layer arranged in between,
placing mechanical reinforcement means through the plurality of partial regions not containing synthetic resin in the initial state,
infusing the plurality of partial regions not containing synthetic resin in the initial state with synthetic resin, and
curing the synthetic resin placed in the plurality of partial regions not containing synthetic resin in the initial state,
wherein the plurality of partial regions not containing synthetic resin in the initial state is produced by inserting a filler during the production of the fiber composite components from fibers and synthetic resin.

8. The method of claim 7 , wherein each of the plurality of partial regions not containing synthetic resin in the initial state is enclosed by a cured region of the fiber composite component.

9. The method of claim 7 , wherein each of the plurality of partial regions not containing synthetic resin in the initial state is essentially rectangular or oval to round in shape.

10. The method of claim 7 , wherein the mechanical reinforcement means are configured as pins to form a pin connection.

11. The method of claim 7 , wherein the mechanical reinforcement means are configured as threads to form a sewn connection.

12. The method of claim 7 , wherein the plurality of partial regions not containing synthetic resin in the initial state is arranged in series with an edge spacing and a web spacing.

13. A method for producing a fiber composite component assembly having at least first and second plate-shaped composite structures made from synthetic resin embedded fibers, the at least first and second fiber composite components having a plurality of partial regions not containing synthetic resin in an initial state, the method comprising:
positioning the at least first and second fiber composite components, the plurality of partial regions not containing synthetic resin in the initial state having been brought to flush conformity with each other,
bonding the at least first and second positioned fiber composite components by an adhesive layer arranged in between,
placing mechanical reinforcement means through the plurality of partial regions not containing synthetic resin in the initial state,
infusing the plurality of partial regions not containing synthetic resin in the initial state with synthetic resin, and
curing the synthetic resin placed in the plurality of partial regions not containing synthetic resin in the initial state,
wherein the plurality of partial regions not containing synthetic resin in the initial state is arranged in series with an edge spacing and a web spacing.

14. The method of claim 13 , wherein the plurality of partial regions not containing synthetic resin in the initial state, are produced by inserting a filler during the production of the fiber composite components from fibers and synthetic resin.

15. The method of claim 13 , wherein each of the plurality of partial regions not containing synthetic resin in the initial state is enclosed by a cured region of the fiber composite component.

16. The method of claim 13 , wherein each of the plurality of partial regions not containing synthetic resin in the initial state is essentially rectangular or oval to round in shape.

17. The method of claim 13 , wherein the mechanical reinforcement means are configured as pins to form a pin connection.

18. The method of claim 13 , wherein the mechanical reinforcement means are configured as threads to form a sewn connection.
