Reprocessable, repairable and recyclable epoxy resins for composites
3R epoxy resins, more sustainable composites CIDETEC’s patented epoxy vitrimer resins provide cure cycles and properties comparable to conventional aerospace epoxies but also allow a range of behaviors more akin to thermoplastics: reprocessing via thermoforming (left), joining via welding, repair of delaminations using heat and pressure (center) and recycling by solvolysis (right) as well as by remolding ground up scraps.
