Beschreibung
Zusammenfassung:	The invention relates to a method of treatment of a fiber-reinforced epoxy composite which comprises contacting the fiber-reinforced epoxy composite with a bio-basedsolvent S chosen from levoglucosenone and/or a levoglucosenone derivative such as cyrene, wherein the treatment temperature generally exceeds by at least 10°C the glass transition temperature of the fiber-reinforced epoxy composite. L'invention concerne un procédé de traitement d'un composite époxy renforcé par des fibres qui comprend la mise en contact du composite époxy renforcé par des fibres avec un solvant biologique S choisi parmi le lévoglucosénone et/ou un dérivé de lévoglucosénone tel que le cyrène, la température de traitement étant généralement supérieure d'au moins 10 °C à la température de transition vitreuse du composite époxy renforcé par des fibres.
