Abstract


The effects of aluminium dross filler on the wear behaviour and thermal stability of epoxy resin (ER) system were investigated. The microstructure of the samples was examined with aids of scanning electron microscope (SEM) to explain the basis for the observed changes in the epoxy resin due to the filler additions. A carbon steel die mould was used for casting the aluminium dross-epoxy resin composites. SEM, X-ray Diffractometer (XRD), Thermogravimetric Analyser (TGA) and spin on disc machine was used to characterise the microstructure, composition, thermal stability and wear behaviour under dry lubrication conditions of the developed composites. The study showed that additions of particulate aluminium dross significantly improved the thermal and wear resistance of the developed composite. The wear resistance increased as the speed and applied load increased. The improved thermal stability is attributable to the presence of new phase (refractory oxide and carbide). The aluminium dross-epoxy resin composite is an excellent material in an application requiring low, tensile strength, low wear resistance and moderate thermal resistance especially in the handle for domestic cooking pot; spoon; screw driver and protecting case for electric iron, television and radio.
