Fly-ash is very rich in SiO 2 and Al 2 O 3 contents compared to red mud. Moreover, reinforcing fly-ash with Al alloys reduces the density and enhances the mechanical and tribological properties of the composite without increasing the cost [9, 37, 38, 43, 44]. This makes fly-ash suitable for use as secondary reinforcements for the hybrid composites.
