摘要: A blend system between two different thermoset polymer, epoxy and unsaturated polyester at ratio 80/20 weight percentage (wt. %) with 10, 20, 30 40 volume (vol. of recycled copper powder as conductive filler was investigated. The polymer composites were undergone some characterization testing which include flexural properties, hardness, thermal stability, electrical properties scanning electron microscopy (SEM). strength the unfilled decreased increasing content. With increase copper, from 0 vol.% to vol.%, a total 350% increment in modulus observed. stability increased loading, 140°C 300°C, 5% loss onset degradation temperature. conductivity composite shown percolation threshold content, where change insulator conductor.
