In this study, recycled copper filled epoxy composites were characterized based on its mechanical, electrical and thermal properties. The effects of different particle sizes of recycled copper were filled with epoxy to investigate the effect of mechanical, electrical and thermal properties. Testing such as morphology, mechanical testing, coefficient of thermal expansion determination, thermogravimetric analysis and electrical conductivity measurement were done to study the properties of the composites. The objectives of this study are: I. To compare the effect of coarse, fine and mixed particle size of recycled copper on the properties of epoxy composites. II. To study the effect of PMMA loading on the properties of epoxy composites using mixed particle size recycled copper. III. To study the effect of surface treatments of copper by using hydrochloric acid and silane on the properties of epoxy/PMMA/recycled copper composites.
