Waste Iron Filings to Improve the Mechanical and Electrical Properties of Glass Fiber-Reinforced Epoxy (GFRE) Composites

Several studies have been conducted to improve the mechanical and other value-added properties of glass fiber-reinforced epoxy (GFRE) composites by addition different fillers. In this work, waste iron filings (WIFs) obtained from steel industry were incorporated into GFRE composite samples in varying amounts up 50% (%w) their electrical properties. The results showed that, with increasing WIF loading 0 w% 50 w%, resultant density gradually increased 1.4 2.1 g/cm3. Surface hardness, Young’s modulus, tensile strength also significantly 9 followed a significant drop more due agglomeration. Overall, modulus any content was higher than that no WIF. elongation at break less ductile upon addition, which decreased 2% 0.6% terms conductivity, 15% or electrically conductive conductivity content. It clear needed establish percolated network render them conductive. containing WIFs around 2.9 kS/m 35 WIFs. These novel could be promising for structural dynamic monitoring systems construction industry. They support efforts utilization materials towards circular economy.
