Tribological Properties Evaluation of Newly Developed Friction Material for Automotive Disc Brake Pad 2020-28-0511

The present work aims at investigating the tribological behavior of a newly developed friction materials and its performance is compared with the commercial brake pad under dry sliding conditions. The friction materials were made in the form of cylindrical pin from three different solid lubricants - graphite, molybdenum disulfide (MoS2) and graphene - keeping the other ingredients fixed. The prepared seven samples (BP01- Graphite, BP02- MoS2, BP03- Graphite &MoS2, BP04- Graphene, BP05- Graphene & Graphite, BP06 - Graphene & MoS2, BP07 - Graphene, Graphite & MoS2) were tested in pin and disc machine and compared to investigate the coefficient of friction, wear resistance followed by hardness test and thermal degradation analysis. The results showed that the wear loss and coefficient of friction of the developed friction materials were strongly influenced by the type and percentage of solid lubricants. The performance of the newly developed friction materials is better than the commercial brake pad which signifies that it could be used in commercial automotive applications.
