Composites can simultaneously enhance materials and designs while having superior mechanical qualities. Composites can have notably better "strength, stiffness, corrosion, wear, and fatigue resistance" than typical composites, which is important for developing aviation constituent parts. The mechanical qualities of the composite fabric must be crafted to fit its intended application or the exploited circumstances. For "the manufacture of aero planes", many metals and synthetic fibers are preferred today. Thousands of people of polymers must be chosen by engineers, but only 0.05 per cent of those may be used in the aerospace sector and still have the desired properties. The choice of proper raw materials from tens of thousands of components has grown to be a significant problem. In a "Multi-criteria decision-making (MCDM)" situation, the optimal material for an aero plane must be selected from a range of alternatives. The finest components for aero plane parts are chosen in this study using strategies focused on "the Grey Relational Analysis (GRA) method" The rank for Al 2024-T3 is 8, Al 2524-T3 is 1, Al 5052-H32 is 6, Al 6061-T6 is 7, Al 7075-T6 is 5, AISI 4130 is 2, Ti-6Al-4V is 3 and AZ31B is 4. The ranking order is “Al 2524-T3 > AISI 4130 > Ti-6Al-4V > AZ31B > Al 7075-T6 > Al 5052-H32 > Al 6061-T6 > Al 2024-T3”. "Aluminum alloy (Al 2524-T3) and steel alloy (AISI 4130)" were discovered to be the first two most appropriate components for aircraft parts, respectively, per the GRA technique.
