Abstract
The tribological behavior of glass fiber reinforced vinylester composites filled with fly ash particulates were studied using a pin-on-disc wear apparatus under dry sliding conditions. The influence of friction and wear parameters like (pv) factor, sliding distance and percentage of filler content, on the friction and sliding wear rate were investigated. A plan of experiments, based on the Taguchi technique, was performed to acquire data in a controlled way. An orthogonal array and analysis of variance (ANOVA) were applied to investigate the influence of process parameters on the coefficient of friction and sliding wear behaviour of these composites. The Taguchi design of experiment approach eliminates the need for repeated experiments and thus saves time, material and cost. Taguchi approach identifies not only the significant control factors but also their interactions influencing the coefficient of friction and specific wear rate predominantly. The results showed that the inclusion of fly ash as filler materials in glass vinylester composites decreases the coefficient of friction and increases the wear resistance of the glass vinylester composites significantly.
