The SIDEFFECT project aims to develop and evaluate dynamic induction welding for thermoplastic fuselage in a low-cost and high-speed context. The final demonstrator integrates the geometric complexities representative of a fuselage panel.
Continuous Induction Welding: a technical challenge for thermoplastic fuselage
Continuous Induction Welding: a technical challenge for thermoplastic fuselage
As part of the constant evolution of the aeronautical market, the sector must meet the objectives of high speed and cost control. Thermoplastic composites offer real advantages such as mechanical performance, excellent environmental performance (fire, fluids, temperature), and industrial perspectives for automation – particularly through the introduction of welding.
The SIDEFFECT project is part of the process of strengthening French thermoplastic sector initiated by the Groupement des Industries Français Aéronautiques et Spatiales (GIFAS).
One innovative feature includes the development of a modelling tool for inductive welding based on the characterisation of the thermal and electrical behaviour, and on the adhesion and degradation phenomena of the composite.
Another involves designing effectors that ensure a perfect welding mastery and good mechanical performance at the interface. And further features include the development of inductors, tools and welding parameters adapted to the complexities of the fuselage panels, including the presence of lightning protection, and demonstrating the validity of induction welding on a stiffened panel representative of the intended application.
The results of the project will raise induction welding maturity and contribute to the emergence of this technology. This technology is intended for the assembly of stiffened thermoplastic panels in general (fuselage, door, gearbox, car) and could be introduced on the next generation of single-aisle civil aircraft.
