▎ 摘　　要

NOVELTY - Conductive network based carbon fiber/phenolic resin reinforced composite material comprises carbon fiber material, phenolic resin, and nano-conductive carbon material; the nano-conductive carbon material is electrochemically deposited on the surface of the carbon fiber and physically dispersed in the phenolic resin. The conductive network based carbon fiber/phenolic resin reinforced composite material is prepared by smearing phenolic resin containing nano-conductive carbon material on the carbon fiber material modified by nano-conductive carbon material, and then curing by hot pressing; the nano conductive carbon material is a composite of carbon nanotubes and graphene. USE - Used as conductive network based carbon fiber/phenolic resin reinforced composite material. ADVANTAGE - The composite material: has improved interface bonding force, and enhanced force electric coupling performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the conductive network based carbon fiber/phenolic resin reinforced composite material comprising (1) dispersing the nano-conductive carbon material I in an aqueous alcohol solution to prepare a dispersion liquid I (3-5 wt.%), using the dispersion liquid I as electrolyte and carbon fiber cloth as anode, adding it into the electrodeposition reaction tank containing the dispersion liquid for electrochemical deposition, carrying electrochemical deposition, taking out carbon fiber cloth and drying to obtain a surface-modified carbon fiber cloth; (2) dispersing the nano-conductive carbon material II in an aqueous alcohol solution to prepare a dispersion liquid II (1-5 wt.%), uniformly mixing the phenolic resin and the dispersion liquid II, making the mass concentration of the nano-conductive carbon material in the phenolic resin be 0.1-0.5 wt.%, and obtaining the phenolic resin containing the nano-conductive carbon material; and (3) applying the phenolic resin containing nano-conductive carbon material obtained in step (2) evenly on the carbon fiber cloth, repeating the application and superimpose the applied carbon fiber cloth up and down to obtain 4-10 layers of carbon fiber cloth, and performing hot-press curing.
