Review on aluminium based functionally graded composites

Abstract

Functional graded composites (FGC) are artificially tailored heterogeneous materials intended to serve the demand of diverse and contradicting properties. Their application ranges from automobiles, gas and oil industries, defence to space. The research reports in this field are scattered. In order to address this, we have attempted to collect the research reports from the field of FGC and critically analysed. This review paper provides a broader picture about Aluminium-based Functionally Graded composites since Al being the lightest commercial metal. The classification of FGCs, fabrication methods used to pro- duce Aluminium-based FGCs are discussed in brief. The properties (microstructure, tensile, wear, hard- ness) of aluminium-based FGCs are collated and presented. Also, an attempt is made to capture information about the effect of different parameters such as particle size and manufacturing methods on the properties of Aluminium-based FGCs. The applications of aluminium based FGCs and challenges involved in the development of aluminium based FGCs are also brought out.
