A challenge for the more environmentally friendly and recyclable fiber composites is that they are sensitive to increased humidity and temperature. Therefore, a careful design and optimization of composite properties and constituents is needed.
In her dissertation, Liva Pupure presents models that can predict the behavior of natural fiber composites.
– With these models, it becomes possible to capture the complex time-dependent material behaviour in different loading conditions. It would also facilitate the choice of materials, says Liva Pupure, PhD in Polymeric Composite Materials at Luleå University of Technology.
– Even if the thesis contributes to a better understanding of fiber composites, more research is needed, such as the simulation of more complex loads and structures. The continued development of fiber composites allows us to reduce dependence on oil-based materials.
Liva Pupure´s research was funded by Interreg IVA Nord in the project ANACOMPO, the EU-project UNELMA, and the project EXCEL, funded by the County Administrative Board of Norrbotten.
