Toughness Effect of Graphene Oxide-Nano Silica on Thermal-Mechanical Performance of Epoxy Resin

A graphene oxide/nano-silica(GOS) hybrid was rapidly and easily synthesized using graphene oxide(GO) and nano-silica(nano-SiO₂) as raw materials, and the synthesized GOS was used to improve the mechanical properties of epoxy resin(EP). The modified EP with different mass fractions of GOS(0, 0.1%, 0.2%, 0.3% and 0.4%) were prepared and studied. The structure, thermal stability, mechanical properties, fracture toughness and failure morphology of the modified EP were analyzed. The result...
