Topic description
Le sujet de thèse proposé vise à développer des méthodes de suivi in-situ de l'état de santé des structures composites à base de fibres de lin et de matrices thermoplastiques (PLA, PP). Ces matériaux, sont plus durables et respectueux de l'environnement que les composites à fibres synthétiques. De part leurs caractéristiques mécaniques intrinsèques, il est possible de les utiliser dans des infrastructures légères (éoliennes, transport, mobilier urbain…). Cependant, leur intégration dans ces structures placées en environnement extérieur pose des défis liés à l'humidité, la température, et les rayonnements UV, qui peuvent dégrader leurs propriétés mécaniques. Les résultats attendus permettront de développer une surveillance continue et une maintenance prédictive, améliorant ainsi la durabilité et la fiabilité de ces matériaux et ouvriront la voie à leur acceptation dans des applications industrielles exigeantes.

The proposed PhD proposal aims to develop in-situ monitoring methods for the health monitoring of composite structures made of flax fibers and thermoplastic matrices (PLA, PP). These materials are more sustainable and environmentally friendly compared to synthetic fiber composites. Due to their intrinsic mechanical properties, they can be used in lightweight infrastructures (wind turbines, transportation, urban furniture, etc.). However, their integration into these structures exposed to outdoor environments presents challenges related to moisture, temperature, and UV radiation, which can degrade their mechanical properties. The expected results will contribute to the development of continuous monitoring and predictive maintenance, thereby enhancing the durability and reliability of these materials and paving the way for their adoption in demanding industrial applications.
