Effect of Carbon Fiber Reinforcement on the Mechanical and Tribological Properties of PA6/PPS Composites

The mechanical and tribological properties of PA6/PPS blend reinforced by different content of carbon fiber were studied in the manuscript. It was found that the strength, modulus and hardness of PA6/PPS blend is improved apparently though breaking elongation rate and impact strength decreases to some extent. Average friction coefficient value of the carbon fiber reinforced PA6/PPS (PA6/PPS-CF) composites at the state stage is lower than PA6/PPS blend and PA6/PPS-CF10% exhibits the lowest friction coefficient of 0.34. As the content of carbon fiber increases, wear rate of the PA6/PPS-CF composites trends to increasing. These results is useful for providing some practical guidance for the application of polymer materials in the tribological field.
