Abstract：Aluminum silicate ceramic fiber / copper fiber reinforced resin-based brake pads were prepared by dry method. The friction coefficients， wear rates and the mechanical-physical properties were appointed as performance indicators. The multi-layer fuzzy comprehensive evaluation was employed to screen out the best formula. Wear mechanism was analyzed by microstructure analysis of worn surfaces， and the influence of different mass of alumina-silicate ceramic fiber/copper fiber on resin-based brake pads was explored. The results show that the fuzzy comprehensive evaluation value of formula F3 （10% aluminum silicate ceramic fiber/15% copper fiber， mass percent ） is the highest and the comprehensive performance is the best. With the decrease of copper fiber content and the increase of aluminum silicate ceramic fiber content， the main wear mechanism gradually changes from abrasive wear to adhesive wear， thermal wear and fatigue wear.
