A systematic review on characterization of hybrid aluminium nanocomposites

Abstract

Hybrid composite materials are increasingly being used in a variety of engineering applications because of its additional features and benefits over traditional composite materials without compromising structural performance and durability. Nanocomposites consists of nanosized reinforcements embedded in a polymer/metal/ceramic matrix, whose structures are found to be more complicated than that of micron size reinforced composites. In this article, a detailed review on fabrication methods, metallography behaviour, mechanical characterization and machinability studies of hybrid nanocomposite is presented. The importance of hybridization of reinforcements and the reason behind improvement in properties due to nanoparticle addition are explained in detail. It is found that smaller quantities of nanoparticle addition in the matrix produces a considerable improvement in properties due to their higher surface area. Hybridization of reinforcement is adopted to develop tailor-made properties of hybrid nanocomposites for specific applications.
