| Sumario: | Composites have been developed with great success by the use of carbon structure reinforcements in metallic materials. Carbon structures reinforced metal matrices possess great potential to be the next generation of advanced composites. Specific advantages include high temperature capability, superior environmental stability, better transverse modulus, shear and fatigue properties. Although many Metal Matrix Composites (MMCs) are attractive for use in different industrial applications, Aluminium Matrix Composites (AMCs) are the most used in advanced applications because they combine acceptable strength, low density, durability, machinability, availability, effectiveness and cost. The present study focuses on the fabrication of aluminium 6061 matrix composite by mechanical milling using carbon particles and fullerenes soots as reinforcements. The aim was to investigate the process feasibility and resulting materials properties such as hardness. The properties obtained were compared with those of the aluminum 6061 without reinforcement. The effect of reinforcement fraction on the properties was also investigated, as well as the milling time. The characterization of the microstructure was done using scanning electron microscopy (SEM), Xray diffraction (XRD) and Raman spectroscopy in order to establish relationships between the structure and mechanical properties of the composites. Furthermore, numerical studies were conducted to obtain the strength of composites. In conclusion, carbon structures reinforced aluminum 6061 composites were successfully produced. The composites showed good mechanical properties. The hardness of the composites increases by over 12%. |
