Material Selection for Fuselage Using Integrated SWARA-MULTIMOORA Approach

The variety of engineering materials is increasing day by day with alloying, post-treatments such as heat treatment, and the production of composite materials, besides pure elements. The selection of the most suitable material for each different part to be produced from such a large material pool is very important. The selection of suitable material for the fuselage, which constitutes an important part of the aircraft, is important in terms of lightness and cost, as well as thermal and mechanical properties. In this study, which aims to select materials for the fuselage of the passenger aircraft, firstly criteria and alternatives have been determined in line with expert opinions. In the study in which criteria such as density, tensile strength, shear strength and cost were taken into consideration, the criteria weights were obtained using SWARA method, and then alternative materials were ranked by MULTIMOORA method according to the criteria weights. As a result, three most suitable materials for the fuselage of the passenger aircraft were determined as CFRP, Ti-6Al-4V and GFRP, respectively.
