Three-body abrasion on wear and frictional performance of treated betelnut fibre reinforced epoxy (T-BFRE) composite
This work aims to investigate the wear and frictional behaviour of a new epoxycomposite based on treatedbetelnutfibres subjected to three-bodyabrasion using different abrasive particle sizes (500 µm, 714 µm and 1430 µm) and sliding velocities (0.026–0.115 m s-1) at constant applied load (5 N) using...

| Summary: | This work aims to investigate the wear and frictional behaviour of a new epoxycomposite based on treatedbetelnutfibres subjected to three-bodyabrasion using different abrasive particle sizes (500 µm, 714 µm and 1430 µm) and sliding velocities (0.026–0.115 m s-1) at constant applied load (5 N) using a newly developed Linear Tribo Machine. The worn surfaces of the composite were studied using scanning electron microscope. The work revealed that the predominant wear mechanism of treatedbetelnutfibrereinforcedepoxy (T-BFRE) composite sliding against grain sands was plastic deformation, pitting and pullout of betelnutfibres. The composite exhibited higher values in frictional coefficient when it was subjected against coarse sand. Besides, the abrasive wear of the composite is depending on the size of abrasive particles and sliding velocity. Higher weight loss is noticed at high sliding velocities. The specific wear rate for the composite subjected to three different sand particles follow the order of: coarse > grain > fine sands respectively. |
