The present invention relates to a method for producing composite laminate (30) comprising at least a first (21) and second (22) face sheet of a fibrous reinforcing material sandwiching between them a sheet of a core material (5), the method comprising the steps of applying the core material (5) between the first and second face sheet (21, 22) and connecting the first and second face sheet (21, 22) to the core material (5). In the composite laminate of this invention the first and second face sheet (21, 22) and the sheet of core material (5) are connected to each other by tufting together the first layer (21), the core (5) and the second layer (22) using a substantially continuous fibrous reinforcing material, at least part of the fibrous reinforcing material extending in Z-direction of the laminate (30).
