Abstract

In a method and a device for recycling a thermoplastic fibre-reinforced composite material, which is in at least one deposition layer in a component ( 1 ), it is suggested that said fibre-reinforced composite material should be pulled off from the remaining component ( 1 ), in the direction of a main fibre direction, in at least one pull-off layer ( 10 ) comprising fibres and matrix material.

Claims (18)

1. A method for recycling thermoplastic fiber composite material which is arranged in at least one deposition layer in a component, in which, in the direction of a main fiber direction, fiber composite material is pulled off the remaining component in at least one pull-off layer comprising fibers and matrix material, wherein during the production of the component, component data relating to the fiber layer and/or laying direction, is stored and is used to assist the recycling method for determining a pull-off direction and/or a starting point for the pull-off process.

2. The method as claimed in claim 1 , wherein the at least one pull-off layer is pulled off a further layer of the fiber composite material or off a base element of another material.

3. The method as claimed in claim 1 , wherein the fiber composite material is heated, at least in a detachment area.

4. The method as claimed in claim 1 , wherein the fiber composite material is pulled off in tape form.

5. The method as claimed in claim 1 , wherein the detached fiber composite material is collected on a storage element.

6. The method as claimed in claim 4 , wherein the detached fiber composite material is collected on a storage element.

7. The method as claimed in claim 1 , wherein a separating tool is used to separate the at least one pull-off layer from the component.

8. The method as claimed in claim 7 , wherein the separating tool is heated.

9. The method as claimed in claim 7 , wherein the at least one pull-off layer is guided by means of a guide roller arranged opposite the separating tool.

10. The method as claimed in claim 1 , wherein the component data is stored in readable form in or on the component.

11. The method as claimed in claim 1 , wherein, by means of at least one non-destructive material testing method, the fiber composite material is examined before, during and/or after the detachment from the rest of the component, and the result of the examination is used to control or regulate the pull-off process or stored for documentation purposes.

12. The method as claimed in claim 1 , wherein markers for position determination are applied to the component.

13. The method as claimed in claim 1 , wherein the shape of the pull-off layer is changed by pressing, by at least one calender, or by at least one pultrusion tool and/or by material application.

14. The method as claimed in claim 1 , wherein fibers and matrix material are separated from each other after being pulled off the component.

15. A method for recycling thermoplastic fiber composite material which is arranged in at least one deposition layer in a component, in which, in the direction of a main fiber direction, fiber composite material is pulled off the remaining component in at least one pull-off layer comprising fibers and matrix material, wherein the shape of the pull-off layer is changed by pressing, by at least one calender, or by at least one pultrusion tool and/or by material application.

16. A device for recycling thermoplastic fiber composite material which is arranged in at least one deposition layer in a component, comprising:

means for pulling off at least one pull-off layer comprising fibers and matrix material of the fiber composite material from the remaining component in the direction of a main fiber direction, and

means for changing the shape of the pull-off layer by pressing by at least one calender, at least one pultrusion tool and/or by material application.
