Sintesi del contesto e degli obiettivi generali del progetto

Due to their high weight specific mechanical properties, fibre reinforced composite materials are increasingly utilized for high performance primary structures within aircraft wing and fuselage components. Yet, further exploitation is often limited due to rather high material and manufacturing costs including post-processing, concessions and rework. Additionally, very conservative engineering allowable are applied in order to account for uncertainties arising from manufacturing as well as operation phase. The SuCoHS project investigated potential weight and cost savings in expanding the use of composite materials in areas of demanding high thermal conditions (temperature and fire).

Lavoro eseguito dall’inizio del progetto fino alla fine del periodo coperto dalla relazione e principali risultati finora ottenuti

In particular, the SuCoHS project investigated new structural concepts with novel multi-material composites that can provide high resistivity against thermal, mechanical and fire loading. These developments also allow higher production rates. They help to make the manufacturing process cost competitive, by using minimal amounts of material and energy, while reducing the requirement for visual inspection or rework. New solutions for the monitoring of structural health are considered in order to enable maintenance activities based directly on the conditions of the structure and the load that it suffers.
3 industrial use cases were defined from real industrial design challenges to validate the new technologies and to demonstrate technical feasibility near to operation environment:
- High temperature nacelle component
- Composite aircraft interior shell
- Tail cone panel substructure

Progressi oltre lo stato dell’arte e potenziale impatto previsto (incluso l’impatto socioeconomico e le implicazioni sociali più ampie del progetto fino ad ora)

SuCoHS brought progress beyond the state of the art in the following fields:
- Material investigation, modification and testing for suiting high temperature and fire resistance requirements
- Automated manufacturing of tailored preforms made from new materials including SHM sensor integration
- Process monitoring of fibre layup and consolidation process including wireless communication and in-situ evaluation for process/ quality control
- Enhanced material models and structural analysis procedures considering uncertainties from manufacturing and loads
- Structural design concepts for temperature and fire resistant structures
