The production of fibre-reinforced composites for use in applications such as type-4 pressure vessels hydrogen storage is achieved through the a thermoset matrix. However, recycling thermosets presents significant challenge due to lack established methods. Epoxy-based vitrimers show characteristics during manufacturing and utilisation phases but exhibit thermoplastic behaviour at elevated temperatures 190 °C. This study investigates industrial-scale carbon fibre reinforced via wet filament winding, exemplified by vessel demonstrator. Processing conditions industrial processes have yet be applied vitrimers; therefore, two vitrimer formulations are compared conventional epoxy thermoset. processability resulting composite quality wound using these materials matrices compared. mechanical properties an interlaminar shear strength test, demonstrating that vitrimeric 19.8% (23 °C) 49.2% (140 improved strength. Consequently, epoxy-based investigated this can employed direct replacement matrix applications, with potential composite. To increase qualities, winding process must adapted vitrimers, since pore free could not achieved.
