NOVELTY - This utility model relates to an Ultra-high strong graphene composite PET fiber electric conduction , belonging to the chemistry fiber technology area. It comprises a fiber main body (1), the fiber main body (1) of present round section, the fiber main body (1) comprises PET fiber part (2) and graphite fiber part (3), the PET fiber part (2) left right two side set with arc groove (4), the graphite fiber part (3) is embedded in arc groove (4) inside, the PET fiber part (2) is set with center has elliptic cavity (5), the fiber main body (1) outside is set with surface with coating layer (6). This utility model new one of ultrahigh strong graphene composite electric conduction PET fiber, because of the increasing of graphite fiber part in PET fiber part left right two side, so greatly reduce of resistance of fiber, fiber with good conductivity, the other PET fiber part center is set with with oval cavity, so fiber elastic modulus high, intensity is good.
