This paper describes the influence of SiC and Al2O3 particles on the wear behaviour of epoxy including PTFE particles. Particle-reinforced epoxy composites (PRCs) covering 5 wt%SiC, 10 wt%SiC and 10 wt%Al2O3 particles plus 5 wt%PTFE were fabricated successfully by mixing technique. The tribological property of PRCs at dry sliding was studied against SiC abrasives on a conventional pin-on-disc machine using Box-Behnken method at different factors. Microstructures were examined through Scanning Electron Microscope (SEM). In addition, second order regression model of weight loss was derived from the main parameters and their interactions. SiC particles indicated a better performance than that of Al2O3 particles due to enough bonding between the fibers and the resin. Furthermore, analysis of variance showed that linear contributions were about 47.60% (load (28.36%) had a considerable effect on the mass loss, followed by speed (11.09%) and material types (8.15%) for PRCs, respectively. However, square effect was about 42.0% while two-way interactions had no effect on the mass loss. © 2021, Springer Nature Singapore Pte Ltd. |
