Process of CNTs/Al6061Composite of compaction and sintering and its mechanical properties were studied. In this study, Al6061 powder (~30㎛) and Multi wall Carbon nanotubes (MWCNTs) were used for this research. Green density of CNTs/Al6061 composite is tested from pressure of 300 to 600 MPa. We obtain maximum green density at 600 MPa. When pressure increased, green density also increased. However Efficiency of compaction is the best at 600 MPa. Sintering process was conducted at 580, 600 and 620℃. The optimum sintering temperature was at 620℃. Analysis of mechanical property of CNTs/Al6061 composite was researched and its mechanical property test is conducted by adding CNTs by 3wt%.
