The mechanical and tribological performance of the PA66/PVDF blends filled with various amount of calcium sulphate whiskers (CSW) was investigated. The whiskers improve the tensile and flexural performance of the PA66/PVDF blends. Meanwhile, the addition of CSW obviously decreases friction coefficient and improves the wear resistance of the blends. With the further increase of CSW, friction coefficient of the blends relatively keeps stable and the wear resistance of the blends slightly decreases. The PA66/PVDF blends filled with 5 wt% CSW exhibited the best anti‐wear ability. FTIR analysis shows that the chemical change has not occurred in the debris. XPS analysis shows that some tribo‐chemical reactions have occurred during friction process and produces some compounds such as FeF 2 , Fe 2 O 3 on the transfer film surfaces. POLYM.
