The current study attempted to evaluate the impact of drilling parameters and delamination on the bearing strength of both neat GFRP (NG) and hybrid GFRP/aluminum (Al)-wire mesh with two various confgurations, frst with Al-mesh in the outer surface of specimen (AG) and the other with Al-mesh in the core of specimen (GA). Drilling procedure is carried out using ∅ 6 mm carbide twist drill with three diferent tip angles (90°, 120° and 135°), as well as Three diferent speeds and feeds (1000, 2000, and 3000 rpm) and (20, 40, and 60 mm/min), respectively. Taguchi and ANOVA analyses are used to analyze the infuence of processing parameters. The fndings showed that AG specimen experienced the least delamination damage. The maximum bearing strength refers to NG specimen, which is 9.6% and 8.7% more than AG and GA specimens, respectively. Drill point angle has the major efect on bearing strength for both AG and GA specimens, while for NG feed rate is of the major efect. The developed regression model displayed a high level of ftness with an average prediction error of less than 3%.
