Résumé
Elium resin from Arkema is an excellent substitute for many thermosetting resins used in the manufacture of structural composites. Indeed, it offers mechanical properties very similar to those of its competitors, but it stands out above all because of its recyclability potential, thus offering the possibility of recovering the fibres at the end of the composites' life for reuse. This opportunity makes it a prime candidate for the eco-design of tomorrow's composite structures, particularly in the transport sector.The aim of this work is to study the durability of a carbon fibre reinforced Elium composite in a wet environment through accelerated ageing tests. The evolution of its mechanical properties was monitored over time, and the reversibility of ageing was also evaluated by completely drying the aged material.It was thus shown that this carbon fibre reinforced Elium composite had good durability properties under harsh ageing conditions, with a loss of longitudinal properties after ageing of less than 10% and in shear of around 20%, but above all an almost complete recovery of its properties after drying.
