Abstract
Epoxy-based composites are widely used in the aircraft, automobile, and microelectronic industries. The incorporation of various nanofillers into epoxy resins can yield high-performance composites having high strength, lightweight, and multifunctional properties. So, this work focuses on the preparation of various inorganic nanoparticles including the waste glass powder received from the broken windowpane filled in an epoxy resin matrix to create high-performance composites. The physical, chemical, mechanical, and electrical properties were investigated for all samples. The results show that the neat epoxy resin shows the lowest HV value and loses the most weight in the abrasion test. Whereas ZnO/epoxy resin composite shows the highest HV, the Al2O3/epoxy resin composite loses less weight in the abrasion test. For electrical results, the resistivity of epoxy resin composites filled with 2 wt% of Al2O3 shows the highest value which is about 45% increase from the pure epoxy resin. Finally, it can be concluded that all inorganic fillers which are SiO2, Al2O3, TiO2, and ZnO including waste glass powder can really improve the hardness, abrasion resistance, and electrical resistivity of the epoxy resin.
