The invention relates to a method for connecting two fuselage sections (1, 2, 21, 22) formed from a fibre-reinforced plastics material, more particularly wound fuselage sections (1, 2, 21, 22) for aircraft fuselage cells, with a number of stringers (10, 11, 35, 36) arranged uniformly parallel to one another spaced out inside on an outer skin (3, 4, 25, 26) to provide a transverse butt joint (5, 30). In order to be able to join together in particular wound carbon fibre reinforced plastics fuselage sections wherein a simple tolerance compensation is possible in a continuous industrial manufacturing process, the method according to the invention has the steps: Aligning a first and second fuselage section (1, 2, 21, 22) relative to one another, heating and customizing at least one transverse butt strap (9, 23) formed from a fibre reinforced thermosoftening plastics material so that a tolerance compensation is possible between deviating cross-sectional geometries of the first and second fuselage section (1, 2, 21, 22) or heating at least one end area (27) of a second fuselage section (2, 22) formed from a fibre-reinforced thermosoftening plastics material and joining the two fuselage sections (1, 2, 21, 22) together.

L'invention concerne un procédé pour relier deux sections de fuselage (1, 2, 21, 22) formées par une matière plastique renforcée par des fibres, notamment des sections de fuselage enroulées (1, 2, 21, 22) pour des cellules de fuselage, comprenant un grand nombre de raidisseurs (10, 11, 35, 36) disposés parallèlement à une distance égale les uns des autres, depuis l'intérieur, sur une surface extérieure (3, 4, 25, 26) en créant un joint transversal (5, 30). Pour pouvoir assembler notamment des sections de fuselage CFC enroulées - une simple compensation des tolérances étant possible dans un processus de fabrication industriel continu - le procédé selon l'invention présente les étapes suivantes : alignement d'une première et d'une deuxième section de fuselage (1, 2, 21, 22) l'une par rapport à l'autre, chauffage et adaptation d'au moins une éclisse de raccordement transversale (9, 23) formée en matière thermoplastique renforcée par des fibres, de manière à ce qu'une compensation des tolérances soit possible entre les géométries variables de la coupe transversale de la première et de la deuxième section de fuselage (1, 2, 21, 22), ou chauffage d'au moins une zone terminale (27) d'une deuxième section de fuselage (2, 22) en matière thermoplastique renforcée par des fibres et assemblage des deux sections de fuselage (1, 2, 21, 22).
