The present study investigates friction and wear of polymeric composites by scratchtest. Polymeric composites consisting of polymethyl methacrylate (PMMA) andpolyethylene (PE) have been filled by sand, aluminum, copper, carbon fibers andcarbon nanotubes. The tribological properties have been determined by scratch test.The experiments revealed that friction coefficient slightly increased up to maximumthen decreased with increasing the applied load. Filling composites by sand increasedfriction coefficient and decreased wear, while copper and aluminum as fillers did notalter frictional behavior but they increased wear. It was observed that addition ofcarbon fibers and carbon nanotubes drastically decreased friction coefficient andwear. It seems that they provided low shear layer in the in the contact surface of thetested composites that decreased friction. Besides, their lubricating action decreasedwear.
