Effect of Molybdenum Disulfide Nano-particles on Dry Sliding Behavior of Carbon Fiber Reinforced Epoxy

摘要

Carbon fiber reinforced polymers shows a rapidly increasing trend toward the replacement process of conventional materials by composites at numerous field applications ranging from house appliances to huge industries, because of its good mechanical, thermal and chemical properties. Carbon Reinforced epoxy composites recommended as an engineering material for a lot of tribological applications. In the present work molybdenum disulfide (MoS2) Nano-particles were used as filling material for enhancing wear resistance and modify the frictional behavior of carbon fiber reinforced epoxy. Proposed composites were tested under dry sliding conditions for different sliding distances against steel counter-face by means of pin-on-disc tribometer. Results shows that; molybdenum disulfide nano powder remarkably reduce friction coefficient of epoxy composites. Beside; using of carbon fiber reinforcement improve wear resistance of proposed epoxy composites. The best combination obtained from carbon fiber reinforced epoxy with 30 % MoS2 and 10 % carbon fiber for long sliding durations.
