Drilling of TiO2 and Zns Filled Gfrp Composites

摘要

In the present work an attempt has been made in order to investigate the drilling behavior of the TiO2 and ZnS filled Glass Fabric Reinforced Polymer Matrix Composites (GFRP). The volume fractions in the matrix were chosen as 1%, 2% and 3%. Drilling has been conducted on a radial drilling machine. Speed of drilling and drill tool diameter were considered as the varying parameters with three levels. Thrust force has been considered as the output parameter and is been measured in each combination of parameters chosen. Results reveal that, the addition of filler will increase the thrust force developed during drilling, also results indicate that, addition of filler will increase thrust force upto 2 volume % of filler thereafter increase in filler content result in almost constant thrust developed. Also it can be observed that, with the increase in drill tool diameter the thrust developed also increases.
