Abstract
The current work is an attempt to study the tribological characteristics of oil palm seed fibre-reinforced polyester (OpSeFRP) composite aged in brake fluid solutions. Two different brake fluid solutions were used with different kinematic viscosities: DOT3 and DOT4 solutions. The ageing period was set as 3 years. A linear tribomachine was used to study the tribological performance of the composite at different fibre loadings; 2.5-3.5 wt %. The tribological test was performed using different applied loads (5-20 N) and different sliding speeds (0.05-0.25 m/s) sliding on a stainless steel counterface at 0.45 km of sliding distance. The outcome of the work showed that the aged samples demonstrated better tribological properties as compared to the unaged samples. For fibre loading of 3.0 wt %, specific wear rate of the OpSeFRP composite was lowered by 28.6 % and 36.7 %, while friction coefficient was reduced by 2.2 % and 11.7 % for DOT3 and DOT4 ageing solutions as compared to the nonaged samples for the same fibre loading conditions. On microscopic analysis of the worn samples, low thermal deformation was evidenced on the aged samples when compared with the unaged samples. For the aged samples, the fibres at the rubbing zone had served as a “coolant” since they had absorbed a certain amount of brake fluid solution. The roughness average of the composite and counterface after the test was high for the unaged samples since the samples experienced high deformation rate.
