Composite Material Selection using GRA MCDM Method

A compound is the result of two or more different substances, each of which has its own characteristics, creating new material to create a new substance rather than the properties of the original components in a particular application. The term composite refers specifically to a structural material (such as plastic) embedded in a fibrous material (such as silicon carbide). Significant properties of OP compounds are achieved by embedding tubes OP a material. The structural value of an object. The bundle of fibers is low, the individual fibers are embedded in a team, binding the fibers together, giving the material rigidity. Selection processes are carried out taking into account the physical, mechanical and wear properties of the composite materials such as density, toughness, tensile strength, flexibility, impact strength and specific wear rate. The fiber-matrix compound also reduces the chance of complete breakdown; When a fiber fails, the crack does not extend to other fibers, whereas cracks that begin in one (or single) material usually continue to spread until that material fails. Key examples of composites are: Reinforced concrete, Reinforced plastic, Wood composites, Ceramic matrix composites, Metal matrix composites, etc. The definition of composite material can be easily developed from the introduction of composite materials. Thus, materials produced from a mixture of two or more components are composite materials. Although component materials have different and unique properties, they can combine the same properties of all components, unlike individual components. The difference between composite materials and compounds and solid solutions is that the individual components in the final product are separate and distinct. In this paper, we used the GRA method to rank alternative parameters such as density, micro-hardness, tensile strength, flexibility and impact strength for composite material selection.
