Aluminum matrix composite (AMC) has been widely used in various industries
such as Automotive, aerospace and marine. One of the constraints to fabricate
AMC is the high costs involved. Fly ash is a coal combustion waste that have
considerable potential as an alternative material for the manufacture of AMC. In
this work, AMC was fabricated through stir casting methods, alumina and fly ash
are utilized as reinforcement. Mechanical properties of the composite were
analysed based on the results of impact test, tensile test and hardness test. Impact
test revealed that the maximum energy absorbed of the AMC is 14.224 Joule with
composition 8 wt% alumina and 12 wt% fly ash. Moreover, tensile strength and
hardness testing result on AMC showed the similar tendency. Mechanical
properties increase linearly with increasing the addition of fly ash. The maximum
value was obtained at 133.74 MPa and 65.37 BHN for tensile strength and
hardness number, respectively. Microstructural results also showed that there was
grain refinement to the addition of fly ash composition, which supports the
mechanical properties result.
