Dry Sliding Wear of Unidirectional Short Castor Oil Fiber Reinforced Epoxy Composite

Abstract:

The application range of natural fiber composites are increasing rapidly in several engineering areas. Unidirectional short castor oil fiber reinforced epoxy composites are fabricated using hand layup process with 40 vol% and 5mm length. Dry sliding wear tests are conducted using pin on disc tribometer. Applied loads are 15, 30 & 45N and track diameters were kept at 100, 110 and 120mm to achieve sliding distances of 1000, 2000 and 3000m respectively with adjustment of running times 6.5, 12 and 16 minutes at speed of 500 RPM. Full factorial DoE is employed and influence of each parameter on amount of wear, CoF and temperature are studied using ANOVA. It is found that load is the highly influential factor affecting amount of wear, CoF and temperature followed by sliding distance and other factors. Also, regression models are developed with good fit. The developed models predicted the results with 0-8 % error.
