Delamination Analysis in Drilling of Coir-Polyester Composites Using Design of Experiments

Abstract

Drilling of fiber reinforced composite materials presents a plethora of questions to the engineers and scientists. A number of research endeavors have been made in the recent years to fully characterize the drilling process of fiber reinforced composite materials. The efforts have been made in the direction of optimization of the operating variables and conditions for minimizing the drilling induced damages. This paper presented the delamination analysis of drilled holes in coir fiber-reinforced polyester composites. The results indicated that the delamination factor in coir fiber-reinforced composites is lower comparing with glass fiber reinforced composites.
