Claim:
1. A method for curing a shell component, comprising: placing a fibre-reinforced stringer prepreg comprising a stringer foot and a stringer web pointing away from a skin portion on the skin portion; arranging a first tool component having a cross-section having four or five sides and a wedge-shaped bevel forming a first sheared edge on a first side edge, on the skin portion, so that the first sheared edge points away from the skin portion; arranging a second tool component having a cross-section having five sides, a wedge-shaped bevel forming a second sheared edge on a first side edge, the wedge angle of the first and the second sheared edge being equal, and a first corner bevel on a second side edge diagonally opposite the first side edge, on the skin portion and at least part of the stringer foot, so that the second sheared edge rests on the first sheared edge and a flange portion of the stringer prepreg projects over the first corner bevel of the second tool component at a flange angle relative to the stringer foot; and composite-curing the stringer prepreg using the first and second tool components to form a composite together with the skin portion.
