Abstract
In a laminate, comprising at least one series of metal layers and fiber-reinforced plastic layers which are attached to one another, at least two different series are provided, these series including a transition, and at the location of the transition at least one of the internal layers is discontinuous and all the other layers are continuous.

A laminate, comprising a first series of continuous metal layers and at least one set of at least two continuous fibre-reinforced plastic layers between and directly bonded with two adjacent metal layers, and a second series of the continuous metal layers and at least one set of the at least two continuous fibre-reinforced plastic layers between and directly bonded with two adjacent metal layers, a transition between the first series and the second series with the continuous metal layers and the continuous fiber-reinforced layers continuing from the first series to the second series through the transition, and the transition including at least one fibre-reinforced plastic layer that is discontinuous at the transition and does not extend through the transition, said continuous layers including outer (metal) layers defining the outer surfaces of the laminate, all of said continuous layers running all the way through said transition without interruption and all of said discontinuous layers ending at the location of said transition.
A laminate, comprising:
- a first series including at least two continuous metal layers defining the outer surfaces of the laminate, and at least one set of at least two fibre-reinforced continuous plastic layers between the surfaces and directly bonded with two adjacent metal layers;
- a second series including the at least two continuous metal layers defining the outer surfaces of the laminate, and the at least one set of at least two fibre-reinforced continuous plastic layers between the surfaces and directly bonded with two adjacent metal layers;
- a transition region between the first series and the second series, wherein the metal layers of the first and second series defining the outer surfaces of the laminate are connected with each other continuously through the transition;
- wherein one of the first and second series comprises a total of 2 metal layers and the other series comprises a total of 3 metal layers, all of said continuous layers running all the way through said transition without interruption, wherein at least one of the fiber-reinforced plastic layers being discontinuous and does not extend through the transition.
A laminate, comprising:
- a first series including at least two continuous metal layers defining the outer surfaces of the laminate, and at least one set of at least two fibre-reinforced continuous plastic layers between the surfaces and directly bonded with two adjacent metal layers;
- a second series including the at least two continuous metal layers defining the outer surfaces of the laminate, and the at least one set of at least two fibre-reinforced continuous plastic layers between the surfaces and directly bonded with two adjacent metal layers;
- a transition region between the first series and the second series, wherein the metal layers of the first and second series defining the outer surfaces of the laminate are connected with each other continuously through the transition;
- wherein one of the first and second series comprises a total of 3 metal layers and the other series comprises a total of 4 metal layers, all of said continuous layers running all the way through said transition without interruption, at least one of the fiber-reinforced plastic layers being discontinuous and does not extend through the transition.
A laminate, comprising:
- a first series including at least two continuous metal layers defining the outer surfaces of the laminate, and at least one set of at least two fibre-reinforced continuous plastic layers between the surfaces and directly bonded with two adjacent metal layers;
- a second series including the at least two continuous metal layers defining the outer surfaces of the laminate, and the at least one set of at least two fibre-reinforced continuous plastic layers between the surfaces and directly bonded with two adjacent metal layers;
- a transition region between the first series and the second series, wherein the metal layers of the first and second series defining the outer surfaces of the laminate are connected with each other continuously through the transition;
- wherein one of the first and second series comprises a total of 4 metal layers and the other series comprises a total of 4 metal layers, all of said continuous layers running all the way through said transition without interruption, at least one of the fiber-reinforced plastic layers being discontinuous and does not extend through the transition.
