Under the direction of the project leader, the post-doctoral researcher will take charge of the installation and commissioning of a new CVD/CVI reactor. Then, as soon as possible, he/she will determine the best conditions to synthesise the first improved CMCs in the new CVD/CVI facility. He will characterise the samples obtained.


- take charge of the installation and launch of the new CVD/CVI reactor,
- choose the most relevant system / chemical precursor for the first feasibility tests,
- carry out a CVI parameter study,
- produce "full CVI" CMC matrices with improved density in optimised preforms,
- establish the relationships between the process parameters and the characteristics of the matrices obtained.


PhD in Physico-chemistry of materials with a profile as a developer/experimenter, preferably in the gaseous route.
Ability to work in a team, ability to adapt and communicate, rigour, organisation and autonomy.
(Very) strong taste for experimentation.

Work Context

Located in Pessac (33), the Laboratory for Thermostructural Composites (LCTS) carries out fundamental and applied research on ceramic matrix composites (CMs). The LCTS is the oldest joint CNRS-University research unit with an industrial partner: the Safran group. The laboratory is also associated with the French Atomic Energy Commission (CEA). CMCs are developed for applications in extreme environments such as aeronautics, space and energy applications.
The proposed position is part of the GaMA project, which concerns the development of next-generation aerospace materials via the gaseous route: the future ceramic matrix composites (CMCs). The objectives are: (i) to increase the densification of preforms, whose initial architecture will have been optimised to reduce the final porosity, and (ii) to obtain materials with new compositions and microstructures that increase their performance. For this purpose, a reactor combining different variants of chemical vapour infiltration/chemical vapour deposition (CVD/CVI) is being designed. This versatile reactor will be a new experimental tool for validating CVD/CVI models and/or applying new development concepts.
