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. Ó 2020 Elsevier Ltd. All rights reserved.

Introduction Aviation and space industry have generally been a pacemaker for improvement and introduction of new material frameworks and production modernizations. The key thrusts for material advancement are reduction in weight, application performance improvement and reduced expenses. The aviation industry is demanding high support from its raw material providers [1]. On one hand, they anticipate minimal effort materials for current air- craft adaptations while then again, new methodologies and pro- pelled materials were anticipated to confront the difficulties of next century air transportation [2]. Aluminium (Al), Titanium (Ti) and polymer matrix composites comprise over 95% of the materials in a typical aircraft structure [3]. Table 1. The assessment of metal matrix composites (MMCs) have been one of the tangible revolutions in materials for the past decades. MMCs are acquiring wide significance in research areas due to its improved mechanical, tribological and dynamic properties when contrasted with fundamental alloys [3,4]. Aluminium based MMCs have become a profitable expansion to the field of newer materials for elite performance in applications [5]. In this work, AlMg4.5Mn alloy was reinforced with nanolcay and studied the dynamic behav- ior of the material for aerospace structural applications. 2. Materials and methods 2.1. Material development The plates used in this study were manufactured using alu- minium alloy AlMg4.5Mn reinforced with nanoclay for varying compositions such as 0, 1.5 and 2.5% wt. Ex-situ synthesized method is used in the fabrication of metal matrix composites. The crucible temperature was maintained to 760 °C–810 °C for 220 min, to convert the solid into liquid state and alumino – silicate layered nanoclay material was mixed into the matrix material using mechanical stirring [6]. The stirring process will disperse the nan- oclay particles into matrix material for better property. The devel- oped composite is poured into the mould and then allowed to solidify. https://doi.org/10.1016/j.matpr.2020.01.096 2214-7853/Ó 2020 Elsevier Ltd. All rights reserved.
