1. Introduction
Te possibilities of obtaining a desirable blend of strength,
rigidity, toughness, or specifc weight using traditional
materials are limited. Composite materials have gained
signifcant attraction in recent times for overcoming these
inadequacies and meeting the excessive requirements of
today’s technology. MMCs have considerably enhanced
properties over conventional alloys, such as high specifc
strength, specifc modulus, dampening capacity, and abra•
sionresistance[1].SomeofMMCs’physicalproperties,such
as their lack of signifcant moisture absorption, reduced
thermalconductivities,andresistancetomostradiations,are
also advantageous. Composites with low•density and low•
cost reinforcing are becoming increasingly popular [2, 3].
Composites reinforced with fyash are anticipated to break
through the cost barrier for broad use in automobile and
light•duty applications [4]. As a result, it is anticipated that
