Abstract

The present study aims to investigate the effect of silicon carbide nanofibers (SiCNF) of 0.1, 0.3, 0.5, 0.7 and 1.0 wt. % contents reinforcing polymethyl methacrylate (PMMA) and epoxy on the tribological behavior of the composites when applying normal loads of 5N, 10N and 15N to a tapered outer race of bearing 30203 rotating against the mentioned composites. The hardness of composites is measured by Shore D Durometer on surfaces of specimens. Friction coefficient of SiCNF/PMMA and SiCNF/Epoxy composites is measured through the monitored rotating test rig at room temperature.
Based on the experiments, results display that there is no apparent improvement in hardness of PMMA filled by SiCNF while of epoxy composites slightly increases by adding SiCNF. Friction coefficient of PMMA composites minimum values are detected at 0.7 wt. % SiCNF, 0.7 wt. % and 1.0 wt. % for 5N, 10N and 15N respectively. The minimum values of epoxy composites friction coefficient are detected at 0.5 wt. % SiCNF content for 5N and 10N, while for 15N appears at 0.5 wt. %. Minimum scar width occurs in SiCNF/PMMA composites at 0.7 wt. % content for 10N and 15N, while it occurs at 0.3 wt. % for 5N normal load. Minimum scar width occurs in epoxy composites at 0.3 wt. % SiCNF for all applied loads.
