This study shows the vibration and low velocity impact behaviour of AlMg4.5Mn reinforced nanoclay nanocomposites at room temperature. Composite samples with different weight percentage of nanoclay were fabricated using liquid state synthesis casting technique, to achieve homogeneous dispersion of Nanoclay. The material characterization was studied by Scanning Electron Microscope (SEM) and Energy-dispersive X-ray spectroscopy (EDS). From the study it was concluded that the Hardness value of the aluminium alloy reinforced nanoclay was increased in addition of nanoclay weight percentage. The natural frequencies of impacted AlMg4.5Mn reinforced nanoclay composites was found to be increased in addition of 2.5 wt% nanoclay. © 2019 Elsevier Ltd.
