Out-of-autoclave manufacturing of thermoplastic fuselage skins with integrated stringers

Abstract

This work presents an investigation into the realisation of a thermoplastic fuselage skin with integrated stringers. In order to minimise costs for such a component, this study utilises an Out-of-Autoclave techniques and prefinished secondary parts (stringers and fillers). The stringers will be integrated during the skin manufacturing without the need for additional joining. The process is optimized for a sufficient laminate quality and a sufficient quality of the weld line. The quality is assessed via Computational Tomography (CT), microscopy, and ultrasonic scanning.
