▎ 摘　　要

NOVELTY - Production of carbon composite fiber involves preparing (S10) a spinning dope by dispersing carbon nanomaterial and polyamic acid in super acid, obtaining (S20) preliminary fiber by spinning the spinning dope, and imidizing (S30) the preliminary fiber to obtain polyimide composite fiber. The spinning dope contains the carbon nanomaterial and polyimide precursor in a mass ratio of 90:10-20:80. USE - Production of carbon composite fiber (claimed). Uses include but are not limited to space, aviation, and national defense applications, polymer electrolyte fuel cell electrode, negative electrode material for lithium-ion secondary battery, and electric double layer supercapacitor electrode. ADVANTAGE - The method provides carbon composite fiber having improved specific strength, specific modulus, electrical conductivity, and thermal conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for carbon composite fiber. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart of the production of carbon composite fiber.
