The authors have characterized the mechanical properties of carbon nanotube (CNT) reinforced copper nanocomposites which were fabricated with an innovative electrochemical co-deposition process. The mechanical strength of Cu/CNT nanocomposites is found to be more than three times greater than that of pure copper. The increased strength is attributed to the good distribution of CNTs and good interfacial bonding between CNT and copper realized by the fabrication method.
