“…When considering the properties individually, it has been found that the hardness played a main role in controlling the abrasive wear [4]. However, other researchers found otherwise [15][16][17]. Therefore, a combination of more than one mechanical property in one product (such as Se, SeH and He) was found to give better correlation [12,13].…”

“…Therefore, certain investigations have attempted to combine more than one mechanical property to one product in order to identify a better relation [12,13]. When combining more than one factor, some found that the relation between the mechanical and tribological properties was highly in agreement with certain published reports [18][19][20][21], they were contradictory to others [15][16][17]. It has been proposed through the published works to correlate the abrasive wear results of polymeric composites to the mechanical properties.…”

“…For instance, in a vast range of research efforts [4,[15][16][17], a poor relation has been found between the mechanical properties and the 3B-A wear rate of twenty polymeric materials. However, in another study, it has been found that the hardness played a main role in controlling the abrasive wear [4].…”

Three body abrasive wear of chopped strand mat glass fibres reinforced polyester (CGRP) was studied for three principal orientations of the fibres, i.e. parallel orientation (P-O), anti-parallel orientation (AP-O) and normal orientation (N-O). The tests were carried out under high stress conditions. A correlation between the specific wear rate and mechanical properties was established.As a result, CGRP composite exhibited better wear characteristic in P-O as opposed to in AP-O and N-O. Different wear mechanisms were observed on the worn surfaces of the materials, including pitting, micro-and/or macro-cracks, as well as breakage and debonding of the fibres.

“…Some general knowledge of polymers and composites has been published summarising global experiences, e.g., wear mechanism and particle detachment, transfer films, and the effects of reinforcements and lubricants [6][7][8]. Large numbers of papers have addressed a given material family, e.g., polyamides, under different conditions, such as abrasive effects [9][10][11][12]. With respect to dry or lubricated conditions of polymer sliding, the principles of some commonly used material families have been tested, and the role of adhesion and surface energy has been discussed [13,14].…”

An engineering approach to dry friction behaviour of numerous engineering plastics with respect to the mechanical properties

The effect of friction on the wear of engineering polymers is a complex and intricate consequence of the micro-and macroscopic interactions of surfaces moving against one another. Friction and the resulting wear are not material properties of plastics; therefore, they cannot be reduced to tabular data of material characteristics that can be found in relevant manuals. Determining friction and the resulting wear involves more complex examination because they are characteristics of a frictional contact system where the effects of the entire system are manifest. Precise knowledge of system conditions is essential to evaluate the friction and resulting wear [1]. These materials have system-dependent tribological behaviour; thus, trends can be defined at a given condition, and the materials can be compared. The system approach is well-known from the literature [2, 199 An engineering approach to dry friction behaviour of numerous engineering plastics with respect to the mechanical properties G. Kalácska Abstract. Twenty-one different commercial-grade engineering polymers, including virgin and composite types, were selected for testing, based on mechanical engineering practices. Three groups were formed according to typical applications: 1) Sliding machine element materials; 2) Mechanically load-carrying machine element materials that are often subjected to friction and wear effects; and 3) Additional two amorphous materials used as chemically resistant materials that have rare sliding load properties. The friction running-in state was tested using a dynamic pin-on-plate test rig. During steady-state friction tests, two pv regimes (0.8 and 2 MPa"ms -1 ) were analysed by a pin-on-disc test system. Based on the measured forces on ground structural steel, surface friction coefficients were calculated and analysed with respect to the mechanical effects of friction. The friction results were evaluated by the measured mechanical properties: yield stress, Shore D hardness, Young's modulus and elongation at the break. The three material groups exhibited different trends in friction with respect to changing mechanical properties. Linear (with varying positive and negative slopes), logarithmic and exponential relationships were observed, and occasionally there were no effects observed. At steady-state friction, the elongation at the break had less effect on the friction coefficients. The dynamic sliding model, which correlates better to real machine element applications, showed that increasing hardness and yield stress decreases friction. During steady-state friction, an increase in pv regime often changed the sign of the linear relationship between the material property and the friction, which agrees with the frictional theory of polymer/steel sliding pairs.
