Abstract: In this study, effect of alumina nano-filler on Three-Body Abrasive wear performance of carbonfiber/epoxy resin composite is evaluated. Carbon fiber/epoxy composite samples without filler and with 0.1%, 0.2%, 0.4% and 0.7% filler additions are fabricated by ‘VARTM’ method. Specimens from the fabricated plates are cut and Three-Body wear investigations arecarried out using Rubber Wheel Abrasive Test Rig in accordance with ASTM G65. Tests are conducted for abrading distances of 250 m, 500 m, 750 m and 1000 m. Three-body abrasive wear studies were conducted and results show decrease in wear loss with increase in nano-filler percentage for varying abrading distances. A comparison between wear rates of different filler content is graphically represented.Also surface morphology is done to investigate the nature of damage at the compositesurface.
