Researcher | Synthetic Fiber | Matrix | Operating Parameters | Findings |
Arul, Vijayaraghavan [112] | Glass fiber | Plastic | · Conventional drilling · Vibration-assisted twist drilling | · Delamination accorded in both techniques · Conventional drilling-induced more delamination |
Khashaba, El-Sonbaty [93] | Glass fiber | Epoxy | · Feed rate · Spindle speed · Drill diameter | · Delamination-free holes have not been obtained · Peel-up and push-out delaminations have been obvious · Delamination size increased with increasing feed · Delamination size increased with increasing feed, spindle speed, and drill diameter |
Shyha, Soo [20] | Carbon fiber | Polymer | · Number of holes · feed rate | · Difficulties in machinability were presented · The worn lip of the drill head was obvious |
