Preparation of CNTs/Al composite power by mechanical ball milling

The CNTs/Al composite powder was prepared by ball milling method,which forms good CNTs/Al composite powder.The investigation of the CNTs concentraion to the result of the composite powder found the different CNTs concentration can get very good composite powder.And for the time of ball milling it found it need some certain time to transform the twist CNTs into short and make the CNTs distribute into the Al matrix homogenously.It provides a good precondition for the fabrication of the CNTs/Al composite powder.
