Abstract

Asbestos and alloys are materials that are frequently used as brake pads; however, because these materials pose risks to human health and the environment, including lung cancer, it is necessary to replace the materials used in brake pads. In place of the current brake pads, composite fibers such as kevlar, sugarcane bagasse, and coconut are studied in this study. The procedure of manually laying up composite molding is used to create the fibers. Tests for tensile, compression, wear, double shear, and Dynamic Mechanical Analysis (DMA) were used to examine the mechanical behavior of the fibers, and a scanning electron microscope (SEM) investigated the fracture surfaces. Natural fibers exhibit excellent adhesive qualities, great ductility, and hardness based on the outcomes of experimental testing. This indicates that the fibers possess the necessary mechanical strength, wear resistance, and thermal stability to perform effectively as friction materials such as in brake pads or clutches where they can withstand high stress and resist degradation during operation. Friction wear can be reduced by analyzing inter-delamination factors through double-shear tests, which show higher shear strength. The DMA test results showed that natural composites have high tangential and loss modules in cyclic temperatures, which contributes to an improvement in their ability to handle high temperatures and friction. The brake pad models were the subject of the FEA analysis. Finally, the performance of polymer-based brake pads is compared with the results from existing brake pad tests.
