▎ 摘　　要

NOVELTY - Graphene reinforced carbon fiber composite comprises 1-5 pts. wt. graphene, 30-40 pts. wt. phenolic epoxy resin, 40-50 pts. wt. carbon fiber cloth, 1-5 pts. wt. graphite powder, 1-5 pts. wt. wollastonite powder, and 3-7 pts. wt. toughening agent. USE - Graphene reinforced carbon fiber composite. ADVANTAGE - Graphene reinforced carbon fiber composite has strong conductivity, resistivity is lower than 3.60 omega meter, high impact toughness, impact toughness value greater than or equal to 5.00 Joule/square centimeter, high hardness, strong wear resistance, shore hardness is greater than or equal to 67, high strength, compressive strength is greater than or equal to 75MPa, and meets common train and railway running need which is effectively solves problem that our country depends on import only sliding to realizes automatic production product replaces import product. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing graphene reinforced carbon fiber composite, which involves: (A) stirring mixture of graphene, phenolic epoxy powder, graphite powder, wollastonite powder, toughener; (B) mixing with mixer to get mixture; (C) gluing roller coated mixture is applied to carbon fiber cloth repeatedly and excess mixture is extruded; (D) mixture is fully bonded to carbon fiber cloth; (E) drying carbon fiber cloth after at 60-100 degrees C; (F) cutting carbon fiber cloth after dried so that four carbon fiber sheets carbon fiber lines is placed in longitudinal direction of carbon fiber cloth; (G) placing carbon fiber lines, five carbon fiber cloth superimposed to formed group according to required pantograph skateboard height required to add up total number of layers of carbon fiber cloth and number of groups superimposed into mold; (H) molding mold into hot pressed on carbon fiber sheet molding pressure is 4.9-6.8 megaPascal at 120-160 degrees C for 2-6 hours; (I) pressing block heat treatment for 3-6 hours at 130-170 degrees C so as to prepared pressure block components are fully crosslinking, cured and eliminated internal stress; and (J) sawing according to slided claim size through heat treatment to obtained pantograph.
