Abstract
The objective of this work is to investigate the effects of the graphene content on the mechanical properties of graphene reinforced aluminum matrix composites. Samples with five distinct volume fractions of graphene reinforcement are considered, namely: 0.0% (pure aluminum), 0.3%, 0.5%, 0.7% and 1%. The composite specimens are produced using powder metallurgy, where the graphene is mix with 99.5% wt. purity aluminum powder using a vortex mixer. In the sequel, the composite samples are compacted in a mold producing cylindrical specimens, with dimensions of 10mm in diameter by 10mm in height, which are taken to furnace for sintering. The microstructure of the composite material is analyzed using a scanning electron microscope (SEM), and the mechanical characterization of the composite material is done by means of compression tests which are conducted using a conducted using a compression machine. Therefore, it will be possible to assess the influence of the graphene content on the material strength behavior, based on the experimental results, considering the different graphene volume fractions. The results are expected to contribute on the understanding and modeling of metal matrix composite materials, which are lightweight materials with interesting mechanical properties, widely employed in various engineering applications, such as, automotive, electronics, military and aerospace activities.
