Carbon fiber-reinforced composite laminates are progressively appealing for several applications in various manufacturing sectors such as aeronautical and automobile, because of their amazingly predominant mechanical properties. This has subsequently led to an increase in research of various machinability techniques emphasizing on both conventional and non-conventional methods. Typically, conventional drilling is one of the most significant machining processes for most kinds of fiber composite laminates. The most unsolicited damage termed as delamination during drilling has recently become one of the most influential research subjects as numerous engineers in manufacturing sector have been trying to prevent this problem over decades. This review paper briefly discusses about the incorporation of different types of fillers in carbon fiber-reinforced composites. The paper also summarizes the steady progress in drilling-induced delamination of carbon fiber laminates. It covers the delamination formation mechanism, delamination suppression strategies, and the optimization of various drilling parameters to reduce the delamination damage. The present article provides researchers an opportunity to deepen their knowledge on specific aspects by exploring different methods for reducing delamination in CFRP composites.
