Enhanced Mould for Thermoplastic Fuselage in and out of Autoclave Consolidation

ended

This project aims to develop our innovative mould for efficient high-volume production of thermoplastic fuselage skin. Within the work of this project, first a process and mould will be developed for in autoclave consolidation, including automated layup, assembly, and transport. Second a mould usable for out of autoclave consolidation e.g. in situ consolidation with enhanced functionality for heating and cooling will be developed. Consolidation of thermoplastics at process temperatures of 400°C new challenges, such as large thermal expansion, temperature stability of sealings and cables. However, it offers opportunities to reduce significantly the cycle time and energy consumption, thereby improving the competitiveness. To overcome these challenges the consortium proposes to manufacture two moulds, one for in autoclave consolidation with limited functionality due to the high environment temperature and an enhanced mould for out of autoclave consolidation. A new temperature profile for the consolidation process is also proposed to be developed. For out of autoclave consolidation adequate surface structures will be investigated.
