Abstract: Polyoxymethylene (POM) composites were prepared by using varying concentrations of copper particles and tested thermally via the Hot Disk method and tribologically via an M-2000 friction and abrasion testing machine. A copper concentration below 10 wt.% didn't affect the thermal properties of the POM composite but using higher concentrations resulted in improved thermal conductivities. Using a copper concentration of 25 wt.% resulted in a thermal conductivity value 35.9% higher than unfilled POM. In addition to the improved thermal properties, the addition of copper particles resulted in a lower friction coefficient of the POM composite.
