Abstract

The current study focuses on the effect of addition graphite filler on mechanical properties of epoxy material. The tensile and bending samples preparation of pure epoxy samples and epoxy with graphite powder with different weight ratio (0.15%, 1%, 2%wt) using ultrasonic dispersion device. The results showed the tensile stress and bending resistance were improved at (0.15%wt) and decreased at (1%, 2% wt), the decrease in tensile strength and bending resistance may be use of less time or low ultrasonic energy. The impact test improved at ratio (1%wt) and decreased at ratio (2% wt). There are decrease in hardness values with increase in graphite wieght fraction due to the lubricant effect of graphite flakes. In addiion of, the distribution of graphite can also affect this result where the penetrant was just on the surface.
