The idealization of this research work is to extend the utilization of the naturally available fibers as a key ingredient in the development of a non-asbestos free brake pad. The fibers used in this work are Caryota urens, which is found all over the Asian regions and abundantly available. The compression molding machine was used to develop the non-asbestos free brake pad. The fibers were added in weight percentages of 5, 10 and 15. The various physical, chemical, and mechanical properties were evaluated. Chase test rig was used to evaluate the tribological properties. The combination of Caryota urens fiber with the barytes had a more significant influence on the tribological properties. The brake pad composites with ten weight percent of Caryota urens fibers based brake pads possessed a good coefficient of friction values with less fade values and less fluctuations. Increasing the weight percentage of Caryota urens fibers in the brake pad formulation had a decreasing trend in the wear performance but increased recovery properties.

The present study deals with the effective usage of crab shell, which is a solid waste in the seafood industry. The crab shell was powdered and treated with chemicals to obtain the chemically treated crab shell powder. The crab shell was powdered and heated to the desired conditions to obtain thermally processed crab shell powder. These two powders so obtained were used with other ingredients in the development of brake pads. For comparison crab shell powder free brake pads were also developed. The developed brake pads were tested for various characteristics as per the industrial standards. Thermal stability was found using Thermogravimetric analysis. The fade and recovery behaviours were estimated for the developed brake pads using Chase test following IS2742 Part-4. The test results indicate that the thermally processed crab shell powder based brake pads showed better thermal stability with a char residue of 37%, while the chemically treated crab shell powder based brake pads had better fade and recovery characteristics with a fade rate of 1.71 % and recovery rate of 99.86 % due to its better heat dissipation and coarse structure. Scanning electron microscopy paved the way to study the worn characteristics of the Chase tested samples. An extensive evaluation method was used to rank the developed brake pads based on the Chase test performance; it also ranked chemically treated crab shell powder-based brake pads as the best performer.

“…Though these fibers were used it has been found to have some problems such as unsteady performance eco friendliness and high in cost. Now the major area of research is on using natural fibers as the key ingredient [6][7][8]. The synthetic fibers were replaced by the natural fibers because of the bio degradability, Cost effectiveness etc Many natural fibers have been used as a key ingredients in the brake pad applications and various findings were obtained.…”

The need of the natural fibers as an alternative for existing synthetic fibers is in great demand for automotive applications. The primary objective of this work is to examine the effect of palm kernel fibers as the replacement of existing synthetic fibers. In this work the palm kernel shell fiber is added in three different weight percentages such as 0%, 5% and 10% and developed in the form of the standard brake pad as per industrial standards by keeping the Barites were used as an space filling ingredient. The various Physical, Chemical and mechanical properties were examined as per industrial standards. Chase Test Rig was used to examine the Tribological properties. Based on the evaluated Results it can be concluded that the coefficient of friction shows a decreasing value on increasing the fiber content. The Brake pad Composites containing 5 wt% of palm kernel fibers possessed high frictional value 0.454 and fade percentage was low with minimal undulations. Palm kernel fibers with 10 weight percentages showed some undulations. It can be concluded Palm Kernel Fiber with 5 weight percentage can be used as a replacement of the synthetic fibers. Scanning Electron Microscopy was used to determine the wear mechanism of the developed brake pad composites.
