Introduction Composite material is the combination of two or more materials with different physical and chemical properties to get a new desirable property, which is suitable for the required application [1, 2]. e reinforcing can be in the form of fiber, particles, or sheets. e reinforcing material is embedded by another material, which is called the matrix. e matrix material is mainly a polymer, whereas the fiber material can be metallic, ceramic, or polymer. In a composite material, the fiber is stiffer and stronger than the matrix, which leads to the primary load carrying member [3]. e composite material has been used other than the structural application. It has been used for electrical, thermal, tribological, and environmental application [4]. Composite material has a new generation of materials that can be used as structural materials in the fast-growing industries of automobiles and aerospace. A composite material is a man-made material in which two or more materials with different properties are combined. e properties of composite materials depend on length, size, orientation, volume/weight, and fiber fraction. Today, consumers and industrial markets are seeing an increase in the daily use of compounds. In the future, due to better performance in different measures, materials used in engineered products will be replaced by composite mate- rials. For this reason, composite materials are used in different fields of application, such as aerospace, marine technology, chemical industry, automotive industry, con- struction, electricity, and other fields of application [5]. Hybrid composite materials must be composed of two or more different reinforcing materials and matrix materials. Due to the shearing effect of reinforcing fibers, this composite material has higher mechanical properties than simple reinforced fiber composite materials. Hybrid composites offer a wide range of applications, including aerospace interiors, naval, civil building, industrial, sporting goods [6], and interior and exterior automotive Hindawi Advances in Materials Science and Engineering Volume 2022, Article ID 5902616, 7 pages https://doi.org/10.1155/2022/5902616
