Abstract
This research paper presents the outcomes of a study aimed at assessing the viability of recycling fibers derived from flax fiber reinforced polymer (FFRP) composites. By implementing solvolysis on a composite panel constructed with flax fabrics and vitrimer resin, the fibers were separated from the covalent adaptable network (CAN) matrix. Microscopy evidence supported by tensile testing of the fabric revealed complete dissolution of the resin with no effect on the mechanical properties. The recycled fibers were incorporated into a second panel with vitrimer resin and tensile testing was conducted to evaluate the impact on the panel’s mechanical properties. The findings revealed a distinct decrease in strength by 22% and a reduction in modulus of elasticity by 13%. These outcomes shed light on the effect of reusing flax fabric, ultimately contributing to our understanding of the feasibility of incorporating recycled fibers into FFRP composites.
