A powder injection moulding-like process for producing carbon nanotubes reinforced copper matrix composites was developed.The process is a promising low-cost and large scale technique for production of complex copper metal matrix nanometer composite.The result reveals that uniform dispersion of carbon nanotubes in copper matrix can be achieved by using polymer-based binder.It is found that debinding，sintering，hot rolling temperature and content of carbon nanotubes have significant effect on the microstructure and properties of composites.The composite with 1 w.t% carbon nanotubes exhibited the best mechanical performance.Furthermore，hot rolling approach plays important role not only for work-hardening effect，but also for uniform distribution of carbon nanotubes in matrix，resulting in significant improvement in density and hardness for composite.
