The objective is to perform fibre-scale tests to characterise the interfacial bonding of ceramic matrix composite materials.
The work consists in preparing samples for push-in and/or push-out tests by nanoindentation and developing numerical models to simulate these tests:
- Set up the methodology of the tests (sample preparation, microscopic analyse, tests)
- Perform tests on different materials, analyse results and determine the materials properties
- Develop numerical models for a best analysis of the tests and to simulate the microstructural behaviour of the materials.
- Mechanics of materials
- Microstructural characterisation
- Numerical modelling & simulation
The position will take place at the LCTS (Laboratoire des Composites Thermostructuraux), on the campus of the University of Bordeaux (Pessac), with the collaboration of Safran Ceramics.
LCTS is a joint unit of CNRS, University of Bordeaux, the Safran group and CEA with 30 years of experience in refractory composites which are high-performance materials used in aerospace and energy applications. LCTS is a single team working in close contact with its non-academic partners, with 33 staff, some 20 PhD candidates and 4 post-doc positions.
Thanks to the excellent thermomechanical properties and low density of ceramic matrix composite (CMCs), Safran Ceramics has the objective to use CMCs in hot parts of the next generation aviation turbines and develops carbide-based CMCs in this aim. The concept of SiC/SiC CMCs developed by Safran Ceramics is to increase the ceramic material toughness with an interphase located between fibres and matrix and working as a mechanical fuse. It is essential to have a good quantification of the interfacial properties to ensure a good mechanical engineering of CMCs parts.
