Abstract
To explore the effect of slag in the fiber on resin-based friction materials, resin-based friction composites were prepared using mineral fibers with different degrees of slag removal. The impact of the mineral fiber slag removal process on the friction and wear properties of resin-based friction materials was experimentally studied. The surface micro-structure after friction was observed and the wear mechanism was analyzed. The results demonstrate that the mineral fiber after slag removal can effectively alleviate heat fading in the friction coefficient of resin-based friction materials and the high temperature friction coefficient can be increased by 22.22%. For resin-based friction materials formed by slag-free mineral fibers, the wear is adhesive primarily in nature. With an increase in the degree of water washing-based slag removal, the wear mechanism shifts from dominant abrasive wear and fatigue wear to only abrasive wear.
