Important results from the project
The project successfully developed graphene-coated flax fibers at both the dry fabric and prepreg composite levels. Testing demonstrated significant improvements in water resistance and mechanical properties at graphene coating loadings of 0.75–1.5 wt.% for dry fabric composites. A 1-meter boat hull was manufactured using coted flax fibers, vacuum infusion and immersed in water at room temperature under ambient conditions to evaluate its water absorption.
Expected long term effects
The project is expected to advance the development of sustainable graphene-based materials by improving water resistance and mechanical properties for marine applications. It also strengthens international collaboration through the G3-DEMO project and the partnership with the University of Sfax. Presentations at international conferences have increased the project´s visibility, fostering further research collaborations and supporting future industrial adoption.
Approach and implementation
The project followed a structured plan focused on the graphene coating of flax fibers and the fabrication of bio-based epoxy composites. Activities included evaluating different graphene coating loadings, assessing mechanical properties and water resistance, and developing a 1-meter boat hull demonstrator. External challenges, such as supply chain limitations, were managed effectively. Collaboration among the project partners was strong and efficient throughout the project.
