NOVELTY - High toughness polyethersulfone resin comprises 65-85 pts. wt. polyethersulfone resin pellets, 15-24 pts. wt. composite fibers, 4-10 pts. wt. hydroxylated graphene, 5-12 pts. wt. polyethylene terephthalate, and 1-4 pts. wt. toughening agent. USE - Used as high toughness polyethersulfone resin. ADVANTAGE - The polyethersulfone resin has high toughness. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing high toughness polyethersulfone resin, comprising (i) drying the polyethersulfone resin pellets and composite fibers, and mixing dried polyethersulfone resin pellets and composite fibers to obtain primary mixture, (ii) mixing the hydroxylated graphene and polyethylene terephthalate, and mixing with the initial mixture and toughening agent to obtain a mixture, and (iii) melting the mixture, extruding and granulating, and drying to obtain finished product
