AHP, Brake Pad Materials, Natural Composites


Asbestos, which is used as brake pad material, is harmful to human health and that is why researchers are trying to find appropriate replacement. The improvement of brake pad performance needs considerable effort including broad research in testing and evaluation of thermal, mechanical, tribological and metallurgical properties of novel materials. Selection of a novel organic brake pad material that meets all properties becomes a complex task. In this paper, attempts have been made to evaluate most criticality property of a novel brake pad material choice for a braking task by utilizing Analytic Hierarchy Process (AHP). In total nine properties of brake pad materials such as Thermal Conductivity (TC), Friction Coefficient (FC), Wear Rate (WR), Specific Gravity (SG), Compressive Strength (CS), Hardness (H), Thickness Swell in Water -TS(W), Thickness Swell in Oil -TS(O) and Flame Resistance (FR) were considered for their comparison. Ranking of the properties from most significant to less critical was analyses by AHP. It was found from the study that wear rate; thermal conductivity and friction coefficient prove to be the most crucial properties for the selection of brake pad material. However, specific gravity, compressive strength and hardness are of equal importance. This work will further contribute in development of asbestos-free eco-friendly composite friction materials for the production of automotive brake pad with an objective of high longevity.
