Resin Variants in Brake Friction Materials: A Tribological Review and Comparative Assessment

The need for ecologically friendly and high-performing materials in car brake pads has prompted a lot of research into resin-based composites. Since they play a crucial part in defining the mechanical, thermal, and tribological characteristics of brake friction materials, resins—especially phenolic resins—have been extensively researched. The resin-based materials used in brake pads are thoroughly examined in this chapter, with an emphasis on how they affect important characteristics including noise reduction, wear resistance, and thermal stability. The backdrop emphasizes how health and environmental concerns have led to a shift from asbestos-based to resin-based composites. The importance of resin matrices in improving durability and performance under severe braking circumstances is emphasized in the introduction. The effects of resin composition, curing behavior, and filler and reinforcement alterations on wear and friction properties are examined in depth. The developments in benzoxazine resins, which provide better mechanical qualities, greater thermal stability, and less environmental effect than traditional phenolic resins, are given particular emphasis. These resins have the potential to solve issues including the demand for sustainable substitutes and resin deterioration at high temperatures. In order to create next-generation brake friction materials, future research should concentrate on refining benzoxazine resin compositions, investigating their compatibility with fillers and additives, and using their special qualities. Insights from this evaluation are intended to help producers and researchers develop and enhance the longevity and performance of vehicle brake pads.
