Abstract:

Material selection plays a very important role in product design and development. In addition, the selection of the right material is of great importance for users to achieve high performance and sustainability. In product development, it is necessary to choose the optimum material that provides maximum performance and minimum cost. Recently, multi-criteria decision making methods have become the preferred methods to select the optimum Çizelge 1material. These methods analyze the problems by breaking them into small parts, then put the parts together and offer an effective solution to the problem. In this study, nanocomposites obtained by adding hexagonal boron carbide (B4C) nanoparticles in different weight ratios (0.5%, 1%, 2%, 3%, 4%, 5%) to the epoxy-based resin; Material selection was carried out by using MOORA and TOPSIS multi-criteria decision making methods by using tensile strength, strain, storage modulus, glass transition temperature (Tg), crosslink density, toughness and price properties. It was concluded that 2% by weight B4C added epoxy nanocomposite should be preferred as the optimum material in the material selections made by MOORA and TOPSIS multi-criteria decision making methods.
