A point of view about dry linear contact between glass fiber reinforced thermoplastic polymers materials on steel

Abstract: In this paper we show, both analytically and graphically, the evolution fo wear occurring on the steel surface in contact with glass fiber-reinforced polymers. The evolution in time of this process depends on the evolution of the friction coefficient in the process of the dry linear contact between polymers and different types of steels. We have made a connection between the theoretical case and the experimental results. The experimental method used was the “wear imprint method” through which the wear depth and wear volume were determined. The wear process is complex and is accompanied by adhesion and corrosion phenomena. Any modification of the input parameters such as speed, temperature, load, quantity of glass fibers in the polymer lead to a change in the evolution of the wear behaviour of the composite material. Keywords: Friction coefficient evolution, contact temperature, wear of the steel surface, influence of steel surface hardness.
