▎ 摘　　要

NOVELTY - Manufacture of a metal-carbon composite material involves performing primary pulverization on the nanocarbon material to form a pulverized nanocarbon material, forming a mixed powder by adding a metal powder to the nanocarbon pulverized product and performing secondary pulverization, performing tertiary pulverization on the mixed powder to form a composite powder, sintering the composite powder to form a sintered material, and heat-treating the sintered material at 400-650° C. USE - Manufacture of metal-carbon composite material used in transport device (all claimed) such as car, ship, train, aircraft, rocket, tank, bearing, wheel, disk, motor, battery pack, fuel tank and aerospace applications. ADVANTAGE - The method provides metal-carbon composite material which is lightweight and having ultra-high strength properties, excellent tensile strength and excellent hardness, and reduces the weight of transportation equipment which reduces fuel efficiency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the metal-carbon composite.
