This research is about developing carbon nanotubes reinforced copper matrix composite by using the powder metallurgy process. The test samples were mixed with different 1-2% volume of carbon nanotube and compacted at 80 kN. The green and sintered density of the samples was recorded. The samples sintered at 900°C in Argon gas for different times. Sintered samples were examined for micro structure in optical microscope and scanning electron microscope. The results of the sintered and theoretical densities showed 98% of the theoretical density.
