Wear characteristic of epoxy resin filled with crushed-silica particles

The dry-sliding wear of epoxy resin filled with 68.5 wt.% of crushed-silica particles (20-40 μm) were evaluated using pin-on-disk tests. At low sliding speeds, the bulk temperatures at contacts were below glass-transition temperature (Tg), i.e. the volume loss decreased with increasing sliding speed. Wear mechanisms were abrasive wear and particle detachment with epoxy-matrix deformation at high temperature.
