Abstract
A skin-stiffener transition assembly (1) with a skin (4) and two L-shaped fiber-reinforced fabric preforms (2, 3) for a flange and a composite gusset filler (5) integrated between said skin (4) and said two L-shaped fiber-reinforced fabric preforms (2, 3). The skin (4) comprises two separate skin layers (7, 8) and the flange comprises a flange layer (6), each of said skin layers (7, 8) and said flange layer (6) being provided with cut outs (9, 10) along one side. Said skin layers (7, 8) and the flange layer (6) are attached to the composite gusset filler (5) with at least one of its cut-outs (9, 10) to one side of the essentially polygonal cross section of the composite gusset filler (5) and with at least one of its adjacent cut-outs (9, 10) to another side of the essentially polygonal cross section of the composite gusset filler (5). The present invention relates as well to a method of manufacture of said skin-stiffener transition assembly (1) and to applications of said skin-stiffener transition assembly (1).
