Thermal, electrical and physical properties of recycled copper filled epoxy composites

Abstract

Thermal, electrical and physical properties of the recycled copper filled epoxy composites were investigated. The recycled copper was collected as a waste from the milling machine. The recycled copper filled epoxy composite was fabricated using mechanical stirrer. The effect of volume fraction of recycled copper of the epoxy composites were studied based on the coefficient of thermal analysis (CTE), electrical conductivity and hardness. Incorporation of recycled copper has decreased the CTE of the composites. The higher the filler loading, the lower the CTE was observed. When the volume fraction of recycled copper increased, the electrical conductivity of the composites was increased. Hardness and density was increased with increasing of filler loading.
