Abstract
A process is proposed for the fabrication of parts with large dimensions formed of a skin ( ) and stiffeners ( ) such as aircraft fuselage segments made of a composite material with a thermoplastic matrix. After stiffeners have been made separately by lay-up, consolidation and shaping, these stiffeners are placed on a tooling ( ) and the skin ( ) is simultaneously fabricated and assembled to the stiffeners ( ) by diffusion welding. More precisely, the skin ( ) is laid up and continuously consolidated by the lay-up head ( ) such that the required part is obtained directly.
