The aim of the research was to develop E-glass-jute fiber reinforced epoxy composites with an additionof Al2O3 and bone powder by using hand layup technique and to compare tribological propertiesof these composites under similar test conditions. The wear experiments were designedaccording to Taguchi’s L27 orthogonal array with three control variables such as sliding velocity,filler content and normal load. The results indicated that the normal load for Al2O3 and filler contentfor bone powder emerged as the significant factors affecting specific wear rate of hybridcomposites. An addition of 10 wt% of bone powder or Al2O3 into E-glass-jute fiber reinforcedepoxy composites increased the wear resistance considerably, and natural waste bone powder canbe used instead of ceramic filler Al2O3 in hybrid composites. After the analysis of control factors,an optimal factor setting has been suggested for specific wear rate and coefficient of friction. Further,the scanning electron microscopy SEM images for worn surfaces of hybrid composites werestudied. Finally, a confirmation test was carried out to validate the results.
