Evaluation of mechanical and Tribological properties of Ecofriendly automotive brake pads

Abstract

The goal of this study is to investigate the synergistic effect of steel newlineslag-molybdenum disulfide particles on non-asbestos organic friction material newlinefade-recovery performance. Steel slag and molybdenum disulfide particles have newlinebeen used individually and in combination to create (three samples-S01, S05 and newlineS10) brake friction materials. According to industry practice, the brake friction newlinematerials have been developed in the form of normal brake pads. The physical, newlinemechanical, and thermal qualities of the created pads are tested according to newlineindustry standards. The Chase test, as defined by IS2742-Part-4, has been used newlineto examine the tribological properties. A scanning electron microscope is used to newlineexamine the worn surfaces. Because of the synergetic nature of the abrasive and newlinelubricant, the brake pads that are loaded with a combination of steel slag and newlinemolybdenum disulfide have demonstrated steady friction and lower wear rate. newlineThis present research explains how steel slag and molybdenum disulfide newlineparticles, both individually and in combination, can improve tribological newlineperformance by providing stable friction with undulations in brake pads. newlineThe purpose of this study is to extract and characterise untreated and newlinesilane-treated natural fibres from Psidium guajava (Guava plants) stems for the newlinepurpose of using in car brake pads. The retting technique has been used to newlineextract fibres from the Psidium guajava plant stems and then, they are treated newlinewith silane. Chemical, physical, and crystallographic characteristics of untreated newlineand silane-treated Psidium guajava fibres have been investigated. These fibres newlineare employed in a brake pad composite that has been created using traditional newlineindustrial techniques and tested for various performance aspects according to newlineindustry standards. newline
