The invention relates to a method of connecting two fuselage sections (1, 2, 21, 22) formed by a fiber-reinforced plastics material, in particular wound fuselage sections (1, 2, 21, 22) for aircraft fuselage cells, having a multiplicity of stringers (10, 11, 35, 36) arranged with a uniform distribut
The invention relates to a method of connecting two fuselage sections (1, 2, 21, 22) formed by a fiber-reinforced plastics material, in particular wound fuselage sections (1, 2, 21, 22) for aircraft fuselage cells, having a multiplicity of stringers (10, 11, 35, 36) arranged with a uniform distribution at a distance from and parallel to one another on the inner side of an outer skin (3, 4, 25, 26), with the formation of a transverse joint (5, 30). In order to be able in particular to join together wound CFRP fuselage sections so that simple tolerance compensation is made possible in a continuous, industrial production process, the method according to the invention comprises the following steps: aligning a first and a second fuselage section (1, 2, 21, 22) with respect to one another, heating and adapting at least one transverse butt strap (9, 23), formed by a fiber-reinforced thermoplastic material, in such a way that tolerance compensation between differing cross-sectional geometries of the first and second fuselage sections (1, 2, 21, 22) is made possible, or heating at least one end region (27) of a second fuselage section (2, 22) formed by a fiber-reinforced thermoplastic material, and joining together the two fuselage sections (1, 2, 21, 22).

1. A method for connecting two fuselage sections formed from a fibre-reinforced plastics material, with a number of stringers arranged uniformly spaced out parallel to one another on an inside of an outer skin to produce a transverse butt joint, the method comprising the steps of: a) aligning a first and a second fuselage section relative to one another,b) connecting at least one transverse butt strap to an end area of the first fuselage section,c) only heating at least one end area of the second fuselage section, which is formed from a fibre-reinforced thermosoftening plastics material, until a temperature corresponding at least to a softening temperature of the fibre-reinforced thermosoftening plastics material is reached,d) pushing the at least one heated end area of the second fuselage section onto the transverse butt strap connected to the first fuselage section,e) compensating for tolerances by one or more of expanding or compressing the heated end area of the second fuselage section, andf) joining the two fuselage sections together. 2. The method according to claim 1, wherein the at least one transverse butt strap is connected to each end area of the first and second fuselage sections by at least one of rivets, screws, adhesive, welding. 3. The method according to claim 1, wherein at least one stringer coupling is heated and customized to enable tolerance compensation. 4. The method according to claim 1, wherein each opposing stringer of the first and second fuselage sections is connected to each at least one stringer coupling. 5. The method according to claim 1, wherein stringer couplings are connected to the stringers by at least one of rivets, screws, adhesive, welding. 6. The method according to claim 1, wherein when heating the at least one transverse butt strap and/or at least one stringer coupling a temperature is reached which corresponds at least to the softening temperature of the fibre-reinforced thermosoftening plastics material comprising a carbon fibre reinforced thermosoftening plastics material. 7. The method according to claim 1, wherein the end area of the second fuselage section is heated by an electrically heatable heating element comprising a heating matmounted at least in the end area. 8. The method according to claim 1 wherein the end area of the second fuselage section when cooling down is shrink-fitted onto the at least one transverse butt strap to produce a press-fit engagement. 9. A transverse butt joint connection between two fuselage sections formed with a fibre-reinforced plastics material, with a number of stringers arranged uniformly parallel to one another spaced out on an inside of an outer skin, with at least one transverse butt strap and a number of stringer couplings, wherein the transverse butt joint is formed by aligning a first fuselage section and a second fuselage section relative to one another, connecting the at least one transverse butt strap to an end area of the first fuselage section, only heating at least one end area of the second fuselage section which is formed from a fibre-reinforced thermosoftening plastics material until a temperature corresponding at least to a softening temperature of the fibre-reinforced thermosoftening plastics material is reached, wherein to enable a tolerance compensation by thermal remoulding and customizing the at least one transverse butt strap and at least one stringer coupling are formed from the fibre-reinforced thermosoftening plastics material comprising a carbon fibre reinforced polyether ether ketone, pushing the at least one heated end area of the second fuselage section onto the transverse butt strap connected to the first fuselage section, compensating for tolerances by one or more of expanding or compressing the heated end area of the second fuselage section, and joining the two fuselage sections together. 10. The transverse butt joint connection according to claim 9, wherein to enable tolerance compensation by heat-conditioned plasticizing at least one of the two fuselage sections is formed from the fibre reinforced thermosoftening plastics material comprising the carbon fibre reinforced polyether ether ketone.
