A method (200) of making a nano-reinforcement filler material (150) for an epoxy resin system (62) for a composite structure (28) is provided. The method (200) includes forming a polymer suspension (100) of polymer nanoparticles (80) suspended in deionized (DI) water (102), and sonicating the polymer suspension (100). The method includes forming a graphene oxide (GO) suspension (106) of GO sheets (90) suspended in DI water (102), and sonicating the GO suspension (106). The method (200) includes mixing the sonicated polymer suspension (100a) and the sonicated GO suspension (106a) to obtain a sonicated mixture (130). The method (200) includes heating the sonicated mixture (130) in an inert atmosphere (132) at an effective temperature (136), and using an electrostatic process (140) to uniformly wrap individual polymer nanoparticles (80a) with individual GO sheets (90a), via an electrostatic interaction reaction (142), to obtain the nano-reinforcement filler material (150) comprising polymer-GO core-shell nanoparticles (152). The method (200) includes washing and drying the nano-reinforcement filler material (150), and using it in the epoxy resin system (62) for the composite structure (28).
