Abstract
The influence of silane treated aluminum oxide (Al2O3) and molybdenum disulphide (MoS2) microfillers on three-body abrasive wear behaviour of carbon fabric reinforced epoxy (C–E) composites was evaluated using a rubber wheel abrasion tester. Three-body wear tests were conducted at different loads/abrading distances. The experimental results showed that the wear volume increased with increasing abrading distance/ load while the specific wear rate decreased with increasing abrading distance. It was found that silane treated aluminum oxide (Al2O3) and molybdenum disulphide (MoS2) as fillers enhanced the abrasion resistance of the C–E composites. Further, the specific wear rate depends on applied load, the type of filler and filler loading. The factorial design was carried out to investigate the effects of individual operating parameters like normal load, abrading distance, type of filler and filler loading and the combined effect of these same parameters, and their interactions with the contact surfaces, on the wear of C–E composites. It was found that the combined effect of operating parameters and their interactions with the contact surfaces had a profound influence on the wear of these composites. The worn surface morphology was performed to investigate the wear mechanisms involved during abrasion process.
