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