In this study, the metal composite with a carbon nanotube sheet laminated on aluminum was manufactured using Spark Plasma Sintering (SPS), and the thermal conductivity and interface microstructure according to the direction were analyzed. Wettability was improved between aluminum and carbon nanotubes through surface treatment using oxygen plasma treatment, and it was confirmed that an oxygen functional group was formed on the surface of the carbon nanotube sheet. Thermal conductivity of the in-plane and through-plane of the manufactured metal composite was 201.7 W/mK and 149.19 W/mK respectively. The formation of an intermediate layer at the interface was confirmed through electron microscopy, which directly affects interfacial bonding strength and thermal conductivity enhancement.
