Dielectric properties of SiC and Al2O3 reinforced Aluminium Metal Matrix Composite (LM25)

Aluminium metal matrix composites are gaining widespread acceptance for aerospace, defense, automobiles, dental and many other industrial applications because of light weight, excellent properties and low cost. These AMMCs offer a large variety of mechanical properties depending on the chemical composition of the Al-matrix. The reinforcement in AMMCs could be in the form of continuous/discontinuous fibers, whisker and particulate as second phase depending on their applications and property requirements. Addition of various reinforcements such as fly ash, TiC, SiC, Al2O3, TiO2, B4C etc., to aluminum matrix will enhance the mechanical and tribological properties. An effort has been made to study the different combinations of reinforcements the composites and how they affect the properties of aluminium metal matrix composites.
