Abstract

Delamination is an inter-ply failure phenomenon induced by drilling and has been recognized as a major damage encountered when drilling composite laminates. The damage caused at the entry and exit of the drilled hole is characterized by delamination factor. In this study, the effects of process parameters such as spindle speed, feed rate, drill diameter and point angle on delamination during drilling of bidirectional carbon fiber reinforced polymer (BD-CFRP) composite laminate have been investigated by using Taguchi design of experiments (DOE). The results obtained are analyzed and validated using response surface methodology (RSM) and analyses of variance (ANOVA). The study reveals that drill diameter and spindle speed are the main contributing process parameters for the variation in the drilling induced delamination of BD-CFRP composite laminate. It is evident from the investigation that feed rate and point angle are least sensitive to the drilling induced delamination of BD-CFRP in high speed steel drills. The study shows that both experimental and the predicted results of delamination factor are in good agreement.
