Mechanical and tribological investigation of jute fiber reinforcement in organic automotive brake pads and water repellency gain in natural fiber reinforced pads

Many studies have shown that the materials used in the composition of brake pads are directly related to friction, wear mechanisms and tribological behavior. Heat-resistant jute fiber is an organic fiber that can be added to the composition of brake pads that can achieve good braking. In the study, pads were produced by adding different amounts of jute fiber using phenolic resin with powder metallurgy method and the results were compared with pads without jute fiber. It was observed that adding 5% jute fiber in addition to aramid fibers used in brake pad manufacturing had positive effects on friction coefficients, friction fluctuations and wear mechanism. At the same time, water absorption values ​​of natural fibers were reduced by 30% and water repellency was provided to the pads. According to sample A, the density of JF3 decreased by 25.4% and shear strength by 39%. The hardness value is at the standard value used in the market.
