Al 2024 Composite, GNP, MWCNT, Microstructure, Electrical Properties


In this experimental study, composite structures were obtained by reinforcing graphene nanoplate and carbon nanotube in different proportions by stir casting method into Al 2024 alloy in the first stage. Then, the microstructures of the composites were examined, and measurements were made to determine their electrical properties. It was observed that the GNP reinforcement material exhibited a more stable distribution in the Al2024 matrix, and MWCNT caused aggregation and porosity in the structure and negatively affected the structural integrity. In both GNP and MWCNT reinforced composites, it was determined that the conductive values increased up to 1% reinforcement rate and started to decrease at higher rates after that. It was determined that 1% of GNP supplemented in Al 2024 increased the electrical conductivity by approximately 20% and MWCNT by 12%. The GNP reinforcement material exhibited a slightly higher conductivity value than MWCNT. It was concluded that the unstable structure due to porosity in MWCNT reinforced composites had a negative effect on conductivity and that the shape changes and specific surface area differences between MWCNT and GNP also affected the conductivity values.
