Characteristics enhancement of MWCNT/AA7075 Nanocomposites for Automotive and aerospace application

Aluminium Metal Matrix Composites (MMCs) are an excellent choice for components that need to be lightweight and have superior mechanical qualities because of their exceptional performance in various engineering applications especially automotive and aerospace. An attempt has been made in the current study work to create the aluminium metal matrix composite via stir casting. A matrix consisting of Aluminium Alloy (AA) 7075 is reinforced with increasing percentages of Multi Walled Carbon Nanotubes (MWCNT) (0wt%, 0.5wt%, 0.1wt%, 1.5wt%, and 2wt%). Investigations were conducted to examine the microstructure, hardness, and additional mechanical attributes such as tensile strength & elongation. The dispersion of MWCNT in AA7075 was examined using a scanning electron microscope (SEM) on the samples. Samples examined under a microscope reveal that MWCNT is well dispersed throughout AA7075. hardness increased by 169,174,183,187 percentages and Tensile strength increased by 145,161,168,187 percentages whereas percentage elongation changed by 23,29,49,53 percentages for 0.5wt%, 0.1wt%, 1.5wt%, and 2wt% CNT, respectively among the characteristics of AA7075.
