Abstract: The friction and wear properties of polyamide 6 (PA6) composites filled with glass fiber (GF) and one of three nano-silicon-based particles were investigated using a MM-200 wear tester. The worn surfaces of the composites were examined through a scanning electric microscopy. It showed that the friction coefficients of the composites were reduced when GF and a silicon-based particle were filled in, and nano-SiO2 was the best. The optimal filler contents for the composites were 5 % SiO2, 3 % Si3N4 and 3 % SiC, respectively. Nano-SiO2 and nano-Si3N4 improved the anti-wear properties of the composites, while nano-SiC increased the wear mass loss of PA6 composites.
