Description

The use of waste steel chips from high-speed grinding processes was examined as an electrically conductive filler in an epoxy resin. The chips were mixed with the liquid epoxy resin, and the mixture was magnetized by being passed through a solenoid coil. The mixture was then cured in an oven. High content of the chips, strong magnetizing currents and high precure temperatures increased the final conductivity of the cured product. By this method, cured products having electrical resistivity of 102 Ω·cm were obtained.
