Abstract: The influence of polyamide-6 (PA6), polyamide-12 (PA12), and their compositions was analyzed to determine the rheological behavior of the feedstock with 43% solid loading. The feedstock with Cu/PA composite constituents were extruded into filaments. The sphericity of particles, particle distribution, and voids was identified using Scanning Electron Microscopy (SEM). The capillary rheometer method was utilized to examine how shear rate and temperature impact the results. The viscosity and shear rate of the material was assessed at different temperatures and shear rates using an L/D ratio of 20 mm and a diameter of 11 mm capillary rheometer. The test results indicated that the polyamide composition influenced the feedstock's rheological properties. The viscosity of the feedstock decreased with an increase in the polyamide composition. Feedstock Cu/PA6 with a composition of 14wt%-Cu has the higher rheological properties among the variation of other composition both for PA-6 and PA-12. Viscosity and Flow energy activation Cu/PA-12 higher than Cu/PA-6.
