Abstract

A connection between two components and a method for connecting two components. The two components have plug-together portions with profiles which can be plugged into one another, the plug-together portions of the two components being plugged into one another in an overlapping region, and a winding region of the two components which at least partially coincides with the overlapping region being wound around by a winding of fiber-reinforced plastic.

First claim

What is claimed is:

1. A connection, comprising:
a first component having a first plug-in portion;
a second component having a second plug-in portion for receipt by the first plug-in portion to define an overlapping region; and
a winding of fiber-reinforced plastic provided around the first component and the second component to define a winding region which overlaps the overlapping region,
wherein the first component and the second component respectively have grooves running around in a circumferential direction of the winding region and outside the overlapping region, to permit a connection of the winding to the first component and the second component with an interlocking engagement in a longitudinal direction.

2. The connection of claim 1 , wherein the first component comprises a first material.

3. The connection of claim 2 , wherein the second component comprises a second material that is different from the first material.

4. The connection of claim 3 , wherein one of the first component and the second component comprises fiber-reinforced plastic.

5. The connection of claim 1 , wherein the first component and the second component each comprises fiber-reinforced plastic.

6. The connection of claim 1 , wherein at least one of the first component and the second component has at least one formation at the winding region.

7. The connection of claim 6 , wherein the at least one formation permits connection of the winding to the first component and the second component with interlocking engagement.

8. The connection of claim 7 , wherein the at least one formation comprises the grooves.

9. A connection, comprising:
a first component having a first plug-in portion;
a second component having a second plug-in portion for receipt by the first plug-in portion to define a first overlapping region;
a third component having a third plug-in portion for receipt by the first plug-in portion and the second plug-in portion to define a second overlapping region; and
a winding of fiber-reinforced plastic provided around the first component, the second component and the third component to define a winding region which overlaps the first overlapping region and the second overlapping region,
wherein the first component, the second component, and the third component respectively have grooves running around in a circumferential direction of the winding region and outside the first overlapping region and the second overlapping region, to permit a connection of the winding to the first component, the second component, and the third component with an interlocking engagement in a longitudinal direction.

10. The connection of claim 9 , wherein at least one of the first component, the second component and the third component has at least one formation at the winding region.

11. The connection of claim 10 , wherein the at least one formation permits connection of the winding to the first component, the second component and the third component with interlocking engagement.

12. The connection of claim 11 , wherein the at least one formation comprises the grooves.

13. A method for connection components, the method comprising:
providing a first component having a first plug-in portion and a second component having a second plug-in portion;
receiving the second plug-in portion into the first plug-in portion to define an overlapping region;
providing a winding of fiber-reinforced plastic around the first component and the second component to define a winding region which overlaps the overlapping region;
curing a matrix material of the winding in a mold, and
wherein the first component and the second component respectively have grooves running around in a circumferential direction of the winding region and outside the overlapping region, to permit a connection of the winding to the first component and the second component with an interlocking engagement in a longitudinal direction.

14. The method of claim 13 , wherein before providing the winding, the winding is formed as a pre-impregnated semi-finished product.

15. The method of claim 13 , comprising, after providing the winding, introducing the matrix material into a dry fiber material of the winding.

16. The method of claim 13 , wherein curing the matrix material comprises winding a dry fiber material without a matrix material, and then injecting the matrix material into the dry fiber material in a mold.

17. The method of claim 13 , further comprising after providing the winding, pouring the matrix material into a dry fiber material in a mold.
