Mechanical behavior of polyethylene terephthalate/copper composite filament

The majority of polymer materials is electrically insulating for their low values of dielectric constants. A method used to solve this problem is the addition of a conductive metal filament into a polymer filament yarn, which can be directly integrated into a textile. The objective of this work is to identify the mechanical behavior and the friction properties of the polyethylene terephthalate (PET)/copper composite filament. The results of the mechanical tests revealed a ductile behavior of this composite filament. Filaments surfaces have been analyzed after friction with Scanning Electron Microscope. Experimental results show a satisfying wear resistance of filaments.
