Epoxy and Polyester Composites' Characteristics under Tribological Loading Conditions.

This research examines the friction and dry wear behaviours of glass fibre-reinforced epoxy (GFRE) and glass fibre-reinforced polyester (GFRP) composites. Three fibre orientations-parallel orientation (P-O), anti-parallel orientation (AP-O), and normal orientation (N-O)-and various sliding distances from 0-15 km were examined. The experiments were carried out using a block-on-ring configuration at room temperature, an applied load of 30 N, and a sliding velocity of 2.
