NOVELTY - Composite material comprises 80-100 pts. wt. epoxy resin, 10-20 pts. wt. curing agent, 10-25 pts. wt. polysulfone (PSF) and 0.01-1 pts. wt. carbon nanotubes and 0.01-1 pts. wt. graphene. USE - Used as composite material comprising epoxy resin . ADVANTAGE - The material improves impact toughness, bending strength, tensile strength and modulus. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparing composite material comprising (a) mixing dry epoxy resin and polysulfone, heating and stirring in an oil bath until the system becomes clear from cloudy, adding carbon nanotubes and/or graphene dispersion liquid, stirring, vacuum defoaming and adding curing agent to obtain curing system and (b) pouring the curing system into a casting grinder with release agent, vacuum degassing and curing; and (2) epoxy resin composite material prepared by the method mentioned above.
