The Mechanical and Tribological Properties of Carbon Fiber Reinforced POM Composites

Different contents of carbon fiber were employed as reinforcement for Polyoxymethylene (POM) composite. All filled and unfilled POM composites were tested against CGr15 ball and representative testing was performed. The effects of carbon fiber content on tribological properties of the POM composites were investigated. The worn surface morphologies of pure POM and its composites were examined by scanning electron microscopy (SEM) and the wear mechanisms were discussed. Results show that all filled polyimides have superior tribological characteristics to unfilled ones. The optimum wear reduction was obtained when the content of carbon fiber is 15vol%.
