Abstract
The invention relates to a method for producing a molding with tapered thickness made of a laminate comprising at least one metal layer and one fiber-reinforced plastic layer connected thereto. The method at least comprises partly pressurizing the laminate at least in the direction of thickness using a pressurizing means, provided that deformation in the plane of the laminate is substantially unimpeded. The invention also relates to a device for implementing the method.

1-22. (canceled)
A method for forming a laminate comprising:
- providing a fiber metal laminate having at least one metal layer and at least one fiber-reinforced plastic layer connected thereto, wherein a thickness of the fiber metal laminate tapers in a longitudinal direction;
- and
- pressurizing the fiber metal laminate at least in the direction of thickness such that a compressive force is exerted on the fiber metal laminate while allowing a deformation of the fiber metal laminate to occur umimpeded to result in a pre-stressed laminate,
- wherein the pre-stressed laminate has an average compressive stress in the at least one metal layer and an average tensile stress in the at least one fiber-reinforced plastic layer in an unloaded state.

A device for producing a laminate comprising:
- a pressurizing means for exerting pressure on a fiber metal laminate having a thickness that tapers in a longitudinal direction, the fiber metal laminate having at least one metal layer and at least one fiber-reinforced plastic layer connected thereto, wherein a compressive force is exerted on the fiber metal laminate while allowing a deformation of the fiber metal laminate to occur umimpeded to result in a pre-stressed laminate,
- wherein the pre-stressed laminate has an average compressive stress in the at least one metal layer and an average tensile stress in the at least one fiber-reinforced plastic layer in an unloaded state.
