NOVELTY - Interlayer modification of fiber reinforced composite material comprises (i) mixing and heating graphene oxide, amino-terminated silicone oil, amino-containing silane coupling agent and reaction solvent through heater, reacting at 150℃ for 13 hours to obtain modified graphene oxide, and mixing and stirring modified graphene oxide, carbon black oxide and organic solvent through stirrer to make binary nanocomposite reinforced phase slurry, (ii) mixing binary nano composite reinforced slurry with matrix resin to obtain first mixed material, removing organic solvent in the first mixture, mixing with curing agent to obtain second mixture, and (iii) coating second mixture on the surface of at least two layers of fiber-reinforced composite material sub-layers, laminating and curing the at least two layers of fiber-reinforced composite material sub-layers to obtain layer intermodified fiber reinforced composites. USE - The method is useful for interlayer modification of fiber reinforced composite material e.g. glass fiber, carbon fiber, aramid fiber and base material. ADVANTAGE - The method enables controlling the feeding device to feed in time when the raw material amount is not enough, so as to ensure stirrer can maintain normal work and improves the stirring efficiency.
