“…This is due to the CNTs capabilities for an effective load transfer from the aluminum matrix during mechanical testing, product of their homogeneous dispersion into the aluminum matrix. Depending on the effectivity of the dispersion technique, a positive effect on the mechanical properties of AMCs reinforced with CNTs has been reported in a wide range of CNTs contents 12,13 . Previous studies have concluded that a good dispersion of CNTs in the matrix is very critical for obtaining high strengthening in the final composite 14,15 the incorporation of uniformly dispersed CNTs into AMCs without losing their unique properties is rather difficult.…”

The aim of the experiment is to study the effect of variation of the percentage composition Al2020 / CNT composite to predict the mechanical, wear properties and Microstructure characterization studies of MMCs and comparing the result with as-cast 7005 alloy. Metal matrix composites are attaining more prominence in the modern-day engineering world. It finds wide applications in various sectors such as defense, aircraft and sports industry. Conclusions from the literature review prompted for the need of a systematic study of various mechanical properties of carbon nanotubes reinforced Al2020 composites. Aluminum 2020 has good strength and is used for manufacturing of variety of components. Composites required for the present study will be prepared by Liquid metallurgy route (Stir casting process). As compared to any other process available for manufacturing of MMCs, Stir casting is generally accepted as competent route and currently practiced commercially. The composite developed by this study will contain varying percentage composition of Al2020 alloy+0.5% CNT, Al2020 alloy+1% CNT and Al2020. The Hardness test was carried out using Brinell testing machine, Compression on Universal testing machine, wear tests were carried out using pin on disc tester and Microstructure characterization is done using Optical Microscope. The hardness and compression test revealed that there is increase in hardness and compression strength of Al2020 alloy with percentage of CNT increased. Microstructure characterization of Al2020 alloy shows the spreading of Carbon nanotube is found to be even in Al2020 alloy matrix and the CNT particles with the Al2020 matrix added to the enhancements of the mechanical and wear properties. Wear test revealed the wear surface morphology of Al2020 alloy shows rough surface with more trenches and crests compared to wear surface morphology of Al2020-CNTs composites.

This research work focus on the formation of AA2024-carbon nanotubes-silicon hybrid metal matrixcomposites. Structure morphology, structural characterization, elemental identification and dielectric properties of AA 2024 in the presence of carbon nanotubes, silicon andits combinations at various proportions was evaluated using SEM, XRD, EDX and Hioki 3532-50 LCR Hi-Tester. A two-stage stir casting method was used for the fabrication of AA2024 hybrid metal matrix composites. It was observed that the size of the AA 2024 + 4% CNT + 2% Si composite wasfound to be 23.6 nm, this shows enhanced results than other composites prepared. Dielectric properties of composites were characterized as a function of composition and frequency. It was found that the dielectric constant, dielectric loss and dissipation factor decreases smoothly with an increase of reinforcements and also frequency.
