Abstract: Thermal conductivity measurements were performed on polyamide 12 and polyamide 11 powders containing carbon nanotubes using the transient plane source (TPS) technique. The effects of powder density and temperature on thermal conductivity were investigated, as well as the effects of using previously heated powder. The thermal conductivity was found to increase with increasing density. For tests involving fresh powder, the thermal conductivity was found to increase linearly with temperature. For the previously heated powder, the thermal conductivity was more constant and higher than the fresh powder.
