A stiffening element 11 comprising at least a first stiffening profile 1and at least a second stiffening profile 2. The first stiffening profile 1 comprises a profile member 4, at least one structural flange 8 is connected to the profile member 4, a through-passage 9 extending through the profile member 4,and at least one support flange 10 is connected to the profile member 4.The second stiffening profile 2 comprises a bottom portion 12 and at least one support side portion 13 connected to the bottom portion 12. Furthermore, the invention relates to a method for manufacturing a stiffening element 11 and a method for manufacturing a reinforced structure 15, wherein the reinforced structure 15 comprises at least one structural element 14 and at least one stiffening element 11.

Method for manufacturing a flexible skin (1) which has at least one insert (2) adhered thereto. In a first step, the skin (1) is moulded on a mould surface (6). In order to adhere the insert (2) to the skin (1), an opening (13) is first made in the skin (1) giving access to the back face (14) of the insert (2). The insert (2) is positioned with its back face against the front face (12) of the skin (1) and an adhering layer (17) is provided which is adhesively connected to the back face (18) of the skin layer (1) which surrounds the opening (13) in the skin layer (1) and, through this opening (13), to the back face (14) of the insert (2). The adhering layer (17) is preferably produced by applying a layer of a hardenable material, in particular a curable polyurethane composition. Since the back face (14) of the insert (2) engages the front side (12) of the skin (1) penetration of hardenable material to the front face (24) of the insert (2) is avoided.
