In this study, the interfacial properties of a sustainable natural fibre, based on flax, with three potentially sustainable advanced matrices are examined. These commercial advanced matrices are (i) a vitrimer that combines the beneficial properties of both thermosets and thermoplastics, (ii) an entirely bio-based thermoset, and (iii) an advanced thermoplastic resin, are investigated for sustainable high-performance fibre reinforced polymer composites. Each of the selected matrices offers either recyclability, repairability, reusability, or the use of renewable sources and a reduction in the emissions of volatile organic compounds. Microbond tests are used to evaluate the interface performance of flax fibres coupled with each of the three matrices: interfacial shear strength and critical fibre length are reported. In conclusion, it is found that the vitrimer and the bio-based thermoset matrices have better adhesion with flax fibre compared to a traditional epoxy matrix, and the advanced thermoplastic resin shows the poorest adhesion with flax fibre.

Abstract
In this study, the interfacial properties of a sustainable natural fibre, based on flax, with three potentially sustainable advanced matrices are examined. These commercial advanced matrices are (i) a vitrimer that combines the beneficial properties of both thermosets and thermoplastics, (ii) an entirely bio-based thermoset, and (iii) an advanced thermoplastic resin, are investigated for sustainable high-performance fibre reinforced polymer composites. Each of the selected matrices offers either recyclability, repairability, reusability, or the use of renewable sources and a reduction in the emissions of volatile organic compounds. Microbond tests are used to evaluate the interface performance of flax fibres coupled with each of the three matrices: interfacial shear strength and critical fibre length are reported. In conclusion, it is found that the vitrimer and the bio-based thermoset matrices have better adhesion with flax fibre compared to a traditional epoxy matrix, and the advanced thermoplastic resin shows the poorest adhesion with flax fibre.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
