▎ 摘　　要

NOVELTY - Preparing graphene high temperature resistant functional fibre involves weighing each raw material includes graphene, modified aerogel, carbon fibre powder, high-strength and high-modulus polyethylene fibre, ceramic powder, resin slurry, additive, modifier, preparing graphene composite resin fibre, preparing high-strength high-temperature resistant functional coating slurry, coating the graphene composite resin fibre obtained slurry to obtain graphene high temperature resistant functional fibre. The fibre obtained winding into the needed specification of the cylinder yarn. USE - Method for preparing graphene high temperature resistant functional fibre. ADVANTAGE - The method has good high temperature resistant effect and long service life.
