The linear dry contact between glass fiber polymer and steel is one of the most complex. It evolves in time as the wear process is under way. From a qualitative point of view, it is known that an increase in friction leads to an increase in wear. This dependency is clarified only in this paper, both qualitatively and quantitatively, because the increase in contact temperature alongside the increase of normal load induces the transfer of plastic material on the wear metal surface, which leads to a modification of the nature of wear. As a result of the filling consisting of short glass fiber,...
