Tomorrow's aircraft fuselage will have to meet increasingly optimized performance requirements and cost reduction objectives. The use of composite materials, associated with the development of new industrial scenarios should enable both these objectives to be achieved. For the last three years, a thermoplastic composite fuselage has been under study [1] and development within the framework of a research project associating Aerospatiale Aircraft, Eurocopter and Dassault-Aviation. Two technological processes studied in this research project, a thermoplastic "sheet forming" process and a process called "in-situ consolidation" are presented and several examples of aeronautical applications are given.
