Research the Al Material Reinforced by CNT(Carbon Nanotubes)
This paper using high energy ball milling(HEM), researched the technology of preparation of Al compound material reinforced by CNT. Researched the different milling time, rotary speed, amount of CNT and sinter technology on properties of hardness and density. Preparation the Al-CNT at milling time about 30 to 100 min, rotational speed is about 300-600/rpm.the wt% of CNT is 0-5%, Analyzed the XRD patterns、SEM and STM micrograph, the results showed the Al material could be reinforced by CNT using HEM. the hardness of Al-CNT is 75 HB and the density is 2.65 g/cm3 when milling 90 min and CNT 3%.
