Abstract
Multi-Walled Carbon Nanotubes (MWCNTs) is considered as viable alternative filler to magnesium matrix composites in order to produce strong and light weight materials via powder metallurgy process. This research is to study the mechanical properties of Mg- MWCNTs composites and analyse the microstructure. The fabrication process of Mg- MWCNTs composites involves mixing of magnesium and MWCNTs, compacting the mixed powder and heating the compact in controlled environment or sintering. The Mg- MWCNTs then will go through density and porosity test, Vickers Hardness test and bending test to study the mechanical properties of the Mg-MWCNTs composites. Scanning Electron Microscope (SEM), optical microscope, and X-Ray Diffraction (XRD) was used to analyse the molecular structure of the Mg-MWCNTs composites. The mechanical properties obtained in this research are greater than the monolithic Mg. The microstructure analysis shows no agglomeration of MWCNTs. The obtained result will be much better by increasing mixing time, increasing the compacting pressure and slowing the sintering temperature rate.
