Abstract: Purpose – This paper aims to investigate the effect of straight phenolic resin content on the fade behavior, frictions and wear characteristics of predeterminedbrakepadcompositematrixhavingspecificamountofbarite(BaSO4),rockwool,Kevlar, graphiteand magnetite. Design/methodology/approach – Different amount of resin ranging between 16 and 20 wt. per cent were added by changing only the filler (barite) content of composite matrix. Subsequently, friction and wear behavior of the composite samples were analyzed using a special pin-on-disc typetestsystem developedforbrakepadsample.The wornsurfaceswereinvestigatedbySEM andthree-dimensional(3D)surfaceprofilometer. Findings – The average coefficient of friction (CoF) of composite samples and temperature of the disc surface showed a linear increase with decreasing the resin content. The sample having 20 wt. per cent resin showed the minimum wear rate with smooth worn surface. But the amount of fade is quite high in that sample. Decreasing resin content decreased the fade formation, and the composite with 16 per cent resin brought about the minimum fade formation. As the fade formation is unwanted in brake pad applications, the composite with 16 wt. per cent resin was proposed asthemostappropriate one consideringtheperformanceparametersrelatedto frictionandwear. Originality/value – This paper optimizes the resin content of composite brake pad materials to achieve the best combination of its triboperformanceandmechanical propertiesand providesvaluableinformationforscientistsandengineersworkinginthatarea.
