Epoxy and Polyester Composites’ Characteristics under Tribological Loading Conditions

This research examines the friction and dry wear behaviours of glass fibre-reinforced epoxy (GFRE) polyester (GFRP) composites. Three fibre orientations—parallel orientation (P–O), anti-parallel (AP–O), normal (N–O)—and various sliding distances from 0–15 km were examined. The experiments carried out using a block-on-ring configuration at room temperature, an applied load 30 N, velocity 2.8 m/s. During sliding, interface temperatures frictional forces captured recorded. Worn surfaces examined scanning electron microscopy to identify damage. highest rates for GFRE composites occurred in those with AP–O fibres, while GFRP P–O fibres. At longer distances, N–O fibres had lowest rates. coefficient was observed higher speeds. value (0.25) rate than maximum speed.
