Influence of heat treatment on wear and hardness properties of MWCNTs reinforced epoxy nanocomposites

Abstract EN

Nanocomposite of carbon nanotube add to epoxy resin material of weight fraction (0.25, 0.5, 0.75 1.0, 1.25, 1.5, 1.75 , 2 & 2.5 wt.

%) were fabricated by dispersing within an epoxy resin using a Ultrasound machine followed by mechanical stirring.

The samples were heat treated at temperature (80 °C for 3 hrs) The mechanical properties of the composites were investigated.

Wear and hardness properties measurements indicated higher wear rate and hardness with increasing concentration of MWCNTs .

The MWCNTs significantly improved the wear resistance and hardness when compare than the pure epoxy.

These note show too after heat treatment of composite with (80 oC for 3 hrs).
