1. 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. 2. The laminate as claimed in claim 1, wherein the second series comprises at least one further discontinuous layer, said at least one further discontinuous layer not extending past the transition. 3. The laminate as claimed in claim 1, in which one series has a different number of layers from another series. 4. The laminate as claimed in claim 3, in which at least one of the metal layers is discontinuous and does not extend past the transition. 5. The laminate as claimed in claim 4, in which there is at least one first set of at least two plastic layers between two metal layers, and the first set is split at the end of a discontinuous metal layer, in such a manner that the at least one of the plastic layers of this first set is located in a plane on a side of the discontinuous metal layer and at least another of said plastic layers of this first set is located in a plane on the opposite side of the discontinuous metal layer. 6. The laminate as claimed in claim 5, in which a second set in the second series has an additional or fewer number of plastic layers from the first set in the first series without a discontinuous metal layer. 7. The laminate as claimed in claim 1, in which the first series comprises three metal layers, and a first set comprising three plastic layers located between each of the metal layers, and a second series that comprises four metal layers, of which three layers extend from the first region and of which an intermediate metal layer is discontinuous and does not extend past the transition into the first series, between each of the four metal layers there is a second set comprising two plastic layers, the second set defined by either:the first set being split at the end of the discontinuous metal layer, in such a manner that two of the plastic layers of this first set are located in a plane on one side of the discontinuous metal layer;the third plastic layer located in a plane on the other side of the discontinuous metal layer and a fiber-reinforced plastic layer that is discontinuous and does not extend past the transition into the first series; orthe first set having a discontinuous plastic layer that does not extend past the transition into the second series. 8. The laminate as claimed in claim 1, in which at least one of the fiber-reinforced plastic layers is discontinuous and does not extend past the transition into the first series. 9. The laminate as claimed in claim 8, in which there are four metal layers, a first set of two plastic layers between each metal layer in the first series, and a second set of three plastic layers between each metal layer in the second series, the second set being defined by the two plastic layers extending from the first series to the second series and a discontinuous plastic layer that does not extend past the second series into the first series. 10. The laminate as claimed in claim 1, in which at least one layer comprises a bonding agent without fiber reinforcement. 11. The laminate as claimed in claim 1, in which at least one of the fibre-reinforced plastic layers is discontinuous at the transition and does not extend past the transition. 12. The laminate as claimed in claim 1 wherein the laminate is used in the construction of an aircraft. 13. 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. 14. 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. 15. 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.
