This paper explores the efficiency of dispersing nano-silica particles in epoxy resin using zirconia ball media by mechanical stirring. Stirring speed (RPM), the time of milling and temperature are the main parameters studied at a fixed media:total silica-epoxy volume ratio. The results show that ball media and heating aid dispersion. At low stirring speed, short stirring duration is more suitable but the reverse is true at high stirring speed.
KEYWORDS:Epoxy resin; mechanical stirring; zirconia ball media
