Influence of Post Heat Treatment Temperatures on Wear Properties of MWCNTs Reinforced Epoxy Composites

摘要

Nanocomposites of epoxy with 0.25, 0.5, 0.75 1.0, 1.25 and 1.5 wt. % Multi walled carbon nanotubes (MWCNT) were fabricated by dispersing within an epoxy resin using a sonication process followed by mechanical stirring. The samples were post heat treated at different temperature 50°C, 100°C and 150°C. The mechanical properties of the composites were investigated. Wear and hardness properties measurements of these nanocomposites indicated higher wear rate and low hardness with increasing concentration of MWCNT and at heat treatment condition. The incorporation of less concentration of MWCNT significantly improved the wear rate and hardness at heat treatment condition compared to pure epoxy samples.
