摘要

In this study, the effects of water ageing on characteristics and properties of basalt fibre (BF)/acrylonitrile-butadiene rubber (NBR) composites were investigated, and the tribological behaviours of the composites that slide against the stainless-steel counterpart under water lubrication at 30-70 degrees C were the main focus. Results showed that with the water temperature increase, the hardness and tear strength of the water-aged samples decreased. Furthermore, both the friction coefficient (COF) and specific wear rate (W-s) of the composites increased with the temperature. The content and the orientation of BFs had no obvious effect on the COF, whereas the parallel-aligned BFs were effective at improving the wear resistance of the composites at both 30 degrees C and 70 degrees C.
