Effect of Flyash Content, Particle Size of Flyash, and Type of Silane Coupling Agents on the Properties of Recycled Poly(ethylene terephthalate)/Flyash Composites

Recent time's polymer waste disposal is a challenging task as the quantity of polymer waste is increasing day by day. Here particulate composites have been developed from recycled poly(ethylene terephtha- late) filled with flyash. Flyash of different particle sizes have been used, and effect of particle size and flyash con- tent on the mechanical properties of composites has been analyzed. Tensile and flexural properties of the compo- sites are found to increase with increase in filler content up to 15% and after that decreases due to the agglomera- tion of flyash particles. SEM studies also showed good dispersion at lower loadings. The use of silane coupling agents was found to increase the flyash/WPET interaction there by increase in mechanical properties is observed.
