Exploration into Tribological Behaviour of Graphite Reinforced Corn Cob Ash Epoxy Composites Utilizing Taguchi Approach

This work concentrates on the utilization of graphite particles as secondary reinforcement in the matrix of ash from corn cobs (CCA) epoxy resin in order to produce epoxy composites with low-friction and wear-resistant. The CCA weight percentage was set at 6%, graphite weight percentages were 3, 5, and 7%, and composites were tested for tribological performance using a pin-on-disc tribometer. The Taguchi approach was used for designing the experiment with a varying function of content of graphite, sliding speed, and normal load. The worn surfaces are examined using electron micrographs to gain a better understanding of the wear process faced by the composites. After going through all of the steps, it was discovered that employing graphite as a secondary reinforcement had a favorable effect on wear and friction, with friction and wear being decreased when compared to the CCA-reinforced epoxy composite.
