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 Hindawi Advances in Materials Science and Engineering Volume 2023, Article ID 9089620, 14 pages https://doi.org/10.1155/2023/9089620
