▎ 摘　　要

NOVELTY - Preparing graphene modified phenolic resin involves adding the graphene into the butanol and mixing uniformly to obtain the graphene solution, melting the phenolic resin to obtain the molten phenolic resin, adding the molten phenolic resin into the graphene solution and mixing uniformly to obtain the composite solution, heating up the composite solution and ultrasonically dispersing to obtain dispersion liquid, heating the dispersion liquid to finish the modification reaction while removing the solvent to obtain product. USE - Method for preparing graphene modified phenolic resin used in composite material. ADVANTAGE - The method has high toughness and low curing temperature, in simple manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing graphene modified phenolic resin composite material, involving: using the graphene modified phenolic resin impregnated fibre preform and curing to obtain product.
