Abstract
This study aimed to improve the composite wear resistance via reinforcement using nano-silica-fused whiskers, and to examine the relationships between wear and mechanical properties. Nano-silica particles were fused onto silicon nitride whiskers at 800 C to roughen the whiskers for retention in the matrix. The silanized powder was incorporated into a resin at mass fractions (%) of 0, 20, 40, 60, 70, and 74. A four-station wear machine was used with specimens immersed in a polymethyl methacrylate bead slurry. Increasing the whisker filler level significantly increased fracture toughness and decreased wear (One-way ANOVA; pCitation
