Abstract—The abrasive wear wear and frictional properties of graphite micro particle filled polyamide 6 matrix composites are investigated in this work. The composites with varying weight fractions of graphite have been prepared by melt mixing technique. Wear tests were conducted using a pin on disc apparatus under dry contact conditions. Mass loss was determined as a function of sliding velocity corresponding to the loads of 5N, 10N and 15N with an abrading distance of 314.2 m. The wear tests showed that graphite fillers improved the wear resistance and reduced the coefficient of friction of the PA6. The best properties achieved with the composite filler content of 25%. The worn surface of a typical specimen was examined by SEM to know the surface morphology.
