“…The research conduct on [2][3][4][5] were mostly related to drilling the conventional FRP composite materials like glass fiber reinforced polymer (GFRP) composite or carbon fiber reinforced polymer (CFRP) composite using various drill point angle, cutting speed and feed rate. None of them have studied on the drilling of hybrid fiber reinforced polymer (HFRP) composite.…”

Abstract. Drilling hybrid fiber reinforced polymer (HFRP) composite is a novel approach in fiber reinforced polymer (FRP) composite machining studies as this material combining two different fibers in a single matrix that resulted in considerable improvement in mechanical properties and cost saving as compared to conventional fiber composite material. This study presents the development and optimized way of drilling HFRP composite at various drilling parameters such as drill point angle, feed rate and cutting speed by using the full factorial design experiment with the combination of analysis of variance (ANOVA) approach and signal to noise (S/N) ratio analysis. The results identified optimum drilling parameters for drilling the HFRP composite using small drill point angle at low feed rate and medium cutting speed that resulted in lower thrust force.

“…The effect of feed rate on delamination is more than that of cutting speed. Unlike them, the works conducted by Khashaba [12,13] show that delamination decreases with cutting speed during drilling of woven-ply GFRP composite laminates; Gaitonde et al [14] also reported that delamination decreases with cutting speed during high speed drilling of thin woven-ply CFRP composite laminates. They also observed that delamination increased by increasing drill point angle of drill bit.…”

“…Almost all researchers reported that feed rate makes the largest contribution to delamination and thrust force and both increase with feed rate at any cutting speeds [28][29][30][31][32][33][34][35][36][37]. The effect of cutting speed is contradictory, since increasing this parameter was reported beneficial in references [38][39][40], while it did affect negatively delamination in references [41][42][43][44]. Tsao and Hocheng observed that a drill with a small diameter produces lower thrust force and consequently less delamination when drilling CFRP laminates [44,45].…”
