Despite the interest in using natural fibres as reinforcements in polymer composites to replace glass fibres, the use of composites based on natural fibres in semi- or structural applications is still limited. This is mainly due to the weak adhesion property between the natural fibres and the polymeric matrix. The present experimental work is focused on the assessment of the effect of different physical and chemical treatments able to increase the adhesion of flax fibres with hydrophobic polymer matrices but with a limited use of chemicals, in an attempt to preserve the environmentally friendly character of plant fibres. In particular a plasma polymerization treatment and enzymatic treatments have been performed on flax yarns. Single-fibre fragmentation test (SFFT) has been performed to investigate the degree of adhesion between the untreated and treated flax yarns and resins (epoxy and vinylester). Depending on the quality of the adhesion, more or fewer fragments were observed and an estimate of the interfacial shear strength (IFSS) has been obtained. Micro-CT analysis has also been used to assess interfacial properties of the single yarn composites and to perform a reconstruction of the breaking area of the flax yarn.
