Delamination is a serious issue during drilling of FRP composites. The purpose of this research is to determine the effect of process parameters on delamination during drilling of kenaf and banana fiber reinforced in epoxy hybrid composite using Taguchi method. The FRP composite was fabricated by hand‐layup technique. The fabricated specimen was drilled using HSS drill bits (5, 10, 15 mm) coated with tungsten carbide. The contemplated process parameters are feed, and speed. The “Minitab 18” software was employed to investigate the data collected by taking advantage of the various statistical and graphical tools available. The trials were carried out by taking advantage of Taguchi's L‐9 factorial design orthogonal array. Through several steps, it was found that the optimum drilling parameters are spindle speed = 3000 rpm; feed = 150 mm/min. Thus, in this research, an attempt has been made to optimize the drilling parameters.
