“…4 show that, the composite material offer less friction force as compared to pure ABS and Friction force increase when applied force and run time increases for both materials. The effect of friction on the wear of engineering polymers is a complex and intricate consequence of the micro and macroscopic interactions of surfaces move against one another (Kalácska et al, 2012). The main tribological properties contributing to friction are adhesion and deformation.…”

Since, the material wear is an important phenomenon influencing the functionality of a part, this research was carried with the aims to study the friction and wear behaviour of parts made of ABS composite material by FDM. This study also compare the friction and wear behaviour of ABS composite with the existing acrylonitrile butadiene styrene (ABS) filament of the FDM machine. The experiment was carried out on the pin-on-disk apparatus according to ASTM G99-04 standard under dry sliding condition that were carried out at room temperature. The load was varied (5, 10, 15 and 20 N) at speed of 286 RPM for the run time of 3 and 5 minutes. The results shown that the applied load and run time significantly affect the wear rate, friction force and friction coefficient of the test samples. Based on the experiment, carbon fiber reinforced ABS specimens showed better wear resistance and durability comparing to pure ABS specimens. This research could be useful to develop a better wear resistance component for various fields of applications.

“…There have been initiatives to find the correlation between the wear behaviour and the mechanical properties of polymers, but difficult or weak correlations have been found, primarily because of the limited condition of the wear systems and the selected material families [15][16][17][18]. In recent years, research has focused on the surface-modified engineering polymers and nano-composites because of new technology that enhances the tribological behaviour by changing the molecular or matrix structure to change the surface or bulk properties [19][20][21].…”

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.

“…On the other hand, the tribological behavior of PA6 treated by N PIII plasma under different conditions (dry, water and oil Mechanical Engineering lubrication) and certain pv regimes was studied [7]. It was concluded that under dry sliding conditions and low pv factor, the PA6 friction coefficient and specific wear are lower than the untreated one.…”
