Aluminium matrix composites belong to the family of materials whose mechanical, tribological, thermal and
electrical properties can be customized effectively. Most of the commercial work on MMCs has been highlighted on
Aluminium as the matrix material. The combination of light weight, environmental resistance and beneficial
mechanical properties has made Aluminium alloys exceedingly popular; these properties also make Aluminium best
suited for use as a matrix metal. The thermophysical properties of these composites can be tailor made and have
excellent specific mechanical properties. These composites can be fabricated with ease. Aluminium matrix composites
reinforced with the particles of Silicon Carbide possess high yield strength, low coefficient of thermal expansion or
thermal expansivity, high modulus of elasticity and excellent wear resistance by maintaining volume proportion up to
20%. Aluminium hybrid composites can be customized to provide moderate Coefficient of Thermal Expansion (CTE)
and high thermal conductivity that are favorable for the applications pertaining to thermal management equipment.
However, it is necessary to evaluate different percentage combinations of reinforcements with matrix Aluminium to
check for thermal stability and to measure thermal conductivity and coefficient of thermal expansion. It is expected
that, Aluminium-Silicon Carbide-Graphite hybrid composites can be used as load bearing material for the above
applications. In this paper, a review about the said hybrid composites to investigate thermal properties for
engineering applications have been discussed based on its technological relevance, applications and research
prospect.
