Abstract: Friction materials are the prime materials which should have higher as well as stable coefficient of friction and lower wear at various braking applications. The demand of these diverse tribological characteristics makes the selection of materials formulation for the friction materials, a critical task. This paper presents an attempt to select the materials formulation for the friction material using two advanced MCDM methods (TOPSIS and COPRAS). Friction materials were prepared at one of the manufacturer from three materials formulation under study (FM01, FM02 and FM03). The experimental set up was developed dedicated to the testing of the friction materials at actual operating conditions. Based on the experimental results, seven criterions were chosen for assessment of the materials formulation in the MCDM approach. TOPSIS and COPRAS methodologies have systematically implemented for evaluation of the materials formulations. Based on the assessments it was concluded that the current approach is useful in evaluation of materials formulation based on the experimental performance. The formulation FM03 was found to be the best material formulation of the three.
