In this study, the tribological behavior of polyester matrix composites filled with silicon dioxide (SiO_2) particles is investigated. The tribological characteristics of pure polyester and 10, 20, 30 and 40 wt% SiO_2 filled polyester composites were comparatively evaluated under dry sliding conditions. Wear tests were carried out at room temperature under the loads of 10, 20, and 30 N at the sliding speed of 1 m/s. The wear test results showed that the SiO_2 particles could improve the wear resistance. The friction coefficient of the polyester was getting increased from 0.228 to 1.1052 with an increase in SiO_2 content depending on applied loads. The results showed that the wear rates of pure polyester and SiO_2 filled polyester composites increased with increase in loads. The wear rates of the SiO_2 filled polyester composites were significantly affected from the SiO_2 content. The wear rate of the polyester changed from 8.0 × 10^{-7} mm^3/m to 1.72 × 10^{-5} mm^3/m depending on SiO_2 contents and applied loads.
