The standards recommended by the Advisory Council for Aeronautics Research in Europe (ACARE) in 2030 require the next generation of civil aircraft engines to reduce their fuel consumption and environmental footprint. Reducing the mass of structural components through the introduction of innovative composite materials, including in the hot parts of engines, is therefore a major industrial challenge. Ceramic Matrix Composites (CMC), due to their excellent mechanical properties up to over 1500°C, are therefore potential candidates for the manufacturing of some hot parts in future commercial aircraft engines. A proposal has been written to work on the characterization of the mechanical properties and modelling of CMC, in particular SiCf/SiC material, submitted to high mechanical loadings and extreme thermal conditions. Several scientific and technological objectives need to be addressed:
- Understand the damage and failure mechanisms under static loading at very high temperatures of a SiCf/SiC material
- Define standard tests to measure mechanical properties (behaviour, damage, failure) at high temperatures
- Propose damage and failure models at different scales to predict behaviour, damage, and failure
- Test and simulate CMC composite structures under static loading (evaluation of predictive capabilities of models)
- Manufacturing, testing and simulation on a CMC demonstrator to validate the developments proposed by the consortium
The project is expected to start its work in early 2027.
