| Research Abstract |
Characteristics of copper and copper alloy matrix composites reinforced with carbon nanotubes(CNTs) have been investigated. Copper and copper alloy powders coated with un-bundled CNTs were prepared by using the surfactant solution containing CNTs. The extruded Cu-Ti composite alloy containing CNTs revealed small decreased of YS compared to the monolithic Cu-Ti alloy. On the other hand, the composites revealed a higher electrical conductivity than that of the monolithic alloy. For example, Cu-Ti with 0. 19 mass% CNTs showed 175. 8 MPa YS(Pure Cu : 83. 6 MPa) and 83. 5 IACS% conductivity.
