The advent of polymer reinforced by fillers had widened the environments of neat polymers by improving their mechanical and tribological behavior as well as other functional properties. The selection of materials plays an important role and determines the working efficiency to increase the productivity. Therefore, mechanical and tribological properties of micro-powdered copper (Cu) reinforced acrylonitrile butadiene styrene (ABS) or polyamide 6–6 (PA66) are investigated in this work. The composites are elaborated by the incorporation of Cu microparticles to the unsaturated ABS and PA66 polymers, respectively. It is observed that mechanical properties like tensile strength are higher in case of 5% Cu for both ABS and PA66 composites. The Young modulus decreases with the increase of copper content in both organic materials. Due to the lubrication ability of copper particles, ABS-Cu composites and PA66–Cu composites show a significant decrease in coefficient of friction. Trends of wear loss in both composite materials are similar, a sharp decrease of the wear resistance ability is observed in case of 5 wt% Cu.

摘要

The advent of polymer reinforced by fillers had widened the environments of neat polymers by improving their mechanical and tribological behavior as well as other functional properties. The selection of materials plays an important role and determines the working efficiency to increase the productivity. Therefore, mechanical and tribological properties of micro-powdered copper (Cu) reinforced acrylonitrile butadiene styrene (ABS) or polyamide 6–6 (PA66) are investigated in this work. The composites are elaborated by the incorporation of Cu microparticles to the unsaturated ABS and PA66 polymers, respectively. It is observed that mechanical properties like tensile strength are higher in case of 5% Cu for both ABS and PA66 composites. The Young modulus decreases with the increase of copper content in both organic materials. Due to the lubrication ability of copper particles, ABS-Cu composites and PA66–Cu composites show a significant decrease in coefficient of friction. Trends of wear loss in both composite materials are similar, a sharp decrease of the wear resistance ability is observed in case of 5 wt% Cu.
