Abstract

A method for producing a product including a composite fiber part and a second part, wherein the second part includes a carrier part, wherein the carrier part is a replica of a press tool configured to be heated and to apply a pressure, the method including applying, in a non-cured state, the composite fiber part on the carrier part, arranging the carrier part including the composite fiber part on the press tool, curing the composite fiber part on the carrier part, and removing the product from the press tool, wherein after removal from the press tool the composite fiber part and the carrier part constitutes together at least a part of the finished product. Also disclosed is a composite fiber product including a composite fiber part and a second part.

Claims (14)

1. A method for producing a product comprising a composite fiber part and a second part, wherein the second part comprises a carrier part, wherein the carrier part is a replica of a press tool configured to be heated and to apply a pressure, comprising the steps of:

applying, in a non-cured state, the composite fiber part on the carrier part;

arranging the carrier part comprising the composite fiber part on the press tool;

curing the composite fiber part on the carrier part; and

removing the product from the press tool, wherein after removal from the press tool the composite fiber part and the carrier part constitutes together at least a part of the finished product; and

wherein the composite fiber part and the carrier part after the step of removal from the press tool is used as the carrier part in a step of repeating the method of producing the product, such that it comprises two or more composite fiber parts and a second part.

2. The method according to claim 1 , wherein the composite fiber part is fixedly connected to the carrier part after curing.

3. The method according to claim 1 , wherein the step of applying comprises applying one or more layers of composite fibers on the carrier part to build up the composite fiber part on the carrier part.

4. The method according to claim 3 , further comprising applying the composite fibers of the composite fiber part to the carrier part automatically or manually, wherein the composite fibers are comprised in at least one of a filament, a roving, a tow, a woven non-crimp fabric, a thermoplastic tape, a prepreg or a towpreg.

5. The method according to claim 1 , wherein the step of curing comprises applying, via interaction of the press tool and the carrier part, heat and/or pressure to the composite fiber part.

6. The method according to claim 1 , further comprising cooling the carrier part after removal from the press tool, and continuing heating the press tool for subsequent reception of at least one other carrier part comprising a composite fiber part.

7. The method according to claim 1 , further comprising storing the carrier part with the applied non-cured composite fiber part during a period of time before it is arranged in the press tool.

8. The method according to claim 1 , wherein the composite fiber part comprises one or more of a glass fiber, a carbon fiber, a aramid fiber, a basalt fiber, a natural fiber, a flax fiber, or a hemp fiber.

9. The method according to claim 1 , wherein the carrier part comprises cured composite fibers.
