Abstract

Disclosed herein is a device for producing composite components including at least one wound fiber reinforced polymer layer, including:
a support with a first holding device and a second holding device for mounting a liner in between, where the first and the second holding device are such that the liner can rotate around a central rotation axis which extends through the first holding device and the second holding device, and at least two movable arms for feeding a fiber structure, where the support is established such that the liner can be moved axially parallel to the central rotation axis and each movable arm for feeding the fiber structure can be moved perpendicular to the central rotation axis. Further disclosed herein is a process for producing composite components using the device.

First claim

1 . A device for producing composite components comprising at least one wound fiber reinforced polymer layer, comprising:
a support with a first holding device and a second holding device for mounting a liner in between, wherein the first and the second holding device are established such that the liner can rotate around a central rotation axis which extends through the first holding device and the second holding device, and at least two movable arms for feeding a fiber structure, wherein the support is established such that the liner can be moved axially parallel to the central rotation axis and each movable arm for feeding the fiber structure is a robotic arm which comprises at least two joints which each allow bending and twisting.

2 . The device according to claim 1 , wherein each movable arm for feeding the fiber structure comprises a device for impregnating the fiber structure.

3 . The device according to claim 2 , wherein the device for impregnating the fiber structure comprises a device to adjust fiber content by volume.

4 . The device according to claim 2 , wherein at least one device for impregnating the fiber structure is placed at an end of each movable arm for feeding the fiber structure which can be moved perpendicular to the central rotation axis.

5 . The device according to claim 2 , wherein the movable arm for feeding the fiber structure is established such that the device for impregnating the fiber structure keeps a horizontal orientation independently of the position of the end of the movable arm for feeding the fiber structure.

6 . The device according to claim 1 , wherein the support and the movable arms for feeding the fiber structure are arranged such that the central rotation axis runs in an angle in the range from 65 to 90° with respect to the horizontal.

7 . The device according to claim 1 , wherein each movable arm for feeding the fiber structure is assigned to a supply for a fiber structure.

8 . The device according to claim 1 , wherein each movable arm for feeding the fiber structure comprises a cutting device for cutting the fiber structure and/or each movable arm for feeding the fiber structure comprises a pincer for placing the fiber structure on the liner.

9 . The device according to claim 1 , wherein a cutting device and a sleeve with pincers for attaching impregnated fibers on the liner are placed on the first holding device or the second holding device.

10 . The device according to claim 1 , wherein the support is mounted to a movable arm which allows for taking a liner from a liner supply, moving the liner into a position for applying the fiber structure, and placing the liner after application of the fiber structure to a following working unit.

11 . The device according to claim 2 , further comprising a device for mixing and metering the matrix material, the device for mixing and metering the matrix material comprising a mixing head which is positioned in close proximity to the device for impregnating the fiber structure.

12 . A process for producing a composite component comprising at least one wound fiber reinforced layer, comprising:
(a) taking a liner from a liner supply with the first holding device and the second holding device of the device according to claim 1 ; (b) moving the liner into a position for applying a fiber structure; (c) attaching the fiber structure on the liner; (d) applying the fiber structure on the liner by means of the movable arms for feeding the fiber structure, wherein the fiber structure is impregnated with a matrix material in a device for impregnating the fiber structure before being applied on the liner, the liner being rotated around the central rotational axis and being moved axially parallel to the central rotational axis during application of the fiber structure to apply the fiber structure in a predefined pattern on the liner; (e) cutting each fiber structure after application of the fiber structure is finished; (f) placing the liner with the applied fiber structure to a curing station; (g) optionally injecting a resin into a mold of the curing station in which the liner with the applied fiber structure is placed to produce a surface coating layer; and (h) curing the matrix material and the resin, if injected.

13 . The process according to claim 12 , wherein the liner is a stiff liner or an inflatable bladder.

14 . The process according to claim 12 , wherein the liner is moved to a predefined position before cutting the fiber structures.

15 . The process according to claim 12 , wherein the liner with the applied fiber structure rotates around a horizontal rotation axis during curing the matrix material.

16 . The device according to claim 1 , wherein each movable arm for feeding the fiber structure comprises a device for impregnating the fiber structure, wherein the device for impregnating the fiber structure comprises a bath for receiving a matrix material, a deflection unit for pressing the fiber structure into the bath, and a draining unit.
