摘要：In the current work to investigate, coconut shell charcoal powder (CSCP) as a composite filler and Musa acuminata stem fiber (MASF) which is used as a reinforcement to study and analyze the potential improvement in wear-resistant property of epoxy matrix composites. For the first time, this finds applications, especially in brake pads where friction exists. Thus, it can be prepared with nontoxic and locally available cheap fibers to produce a prospective tribo material. MASF reinforced with epoxy composites was prepared with variations of CSCP 10%, 20%, 30%, and without CSCP. The composite was prepared by hand layup and open mold technique with a fiber length of 20 mm and fiber percentage of 30 wt.% for all kinds of samples. A computerized pin on disc machine was used to test tribological properties of the composites and the test was conducted with various parameters namely type of treatment, applied normal loads (15, 20, 25, and 30 N), and sliding speed (1.5, 2.0, and 2.5 m/s) for a constant sliding time of 15 min under dry condition. From the result, it was concluded that the weight loss of addition of CSCP filler to natural fiber reinforced epoxy composites got reduced by 15% and 39%, while the coefficient of friction was also decreased by 41% and 39% respectively. A scanning electron microscope (SEM) was used to observe the worn surface and wreckage in the tested composite samples. As a conclusion, experiment results and microscope observation indicate that 30 wt.% of addition of CSCP filler to natural fiber reinforced epoxy composites exhibited good wear resistance compared to other.
