METHOD FOR PRODUCING FUSELAGE CELL SECTIONS FOR AIRCRAFT WITH COMPOSITE FIBRE MATERIALS, AND A DEVICE

摘要

The invention relates to a production method for producing seamless, integral and essentially hollow cylindrical components 5, in particular fuselage sections of aircraft. The method comprises the following steps: a) Application of a first vacuum film 3 to a stable winding core 2 and evacuation of the first vacuum film 3, b) depositing of the fuselage section 5 in laminated fashion on the winding core 2 by winding the same, c) aeration of the first vacuum film 3, d) application of an outer mould 6, that is unstable compared to the stable winding core, to the fuselage section 5, wherein the winding core 2 stabilises the outer mould 6, e) application of a second vacuum film 7 to the outer mould 6 and evaluation of the second vacuum film 7 in order to drawl the fuselage section 5 closer to the outer mould 6 and detach it from the winding core 2 at least in regions, f) hardening of the entire arrangement in an autoclave to produce the finished fuselage section. This gives rise to a high surface quality of the component 5. Moreover, very high dimensional stability is achieved, particularly in terms of a cross-sectional geometry of the component 5 that is to be adhered to. In addition the invention relates to a device for executing the method.
