ABSTRACT = {The aim of this study is to analyze the interfacial and the frictional properties of copper (Cu)
reinforced polyethylene terephthalate (PET) filament. This Cu-Embedded PET filament will be
used as an information transmitter. This filament was prepared by a co-extrusion process.
Mechanical properties of these filaments have been quantified by tensile and pull-out analyses.
It is shown that the mechanical properties of composite filament were improved by adding the
copper filament (from 0.82 to 1.2 GPa). The results of the pull-out test revealed some adhesion
between the copper and the PET despite the existence of a slippage of the copper filament in
the PET matrix. Regarding the variation of the maximum pull-out load, according to the embedded
length, a linearity relationship is observed. Therefore, it can be assumed that the interfacial
shear stress is constant over the embedded length. Filaments surfaces have been analyzed
after friction with Scanning Electron Microscope. Experimental results show a satisfying wear
resistance of filaments, even if friction is able to induce some structural modifications of the
polymer surface.},
