Carbon fiber reinforced polymer (CFRP),owing to its corrosion resistance and high specific strength,is often stacked with metallic alloys to form hybrid laminates for aerospace and other state-of-the-art applications.Owing to the disparate machinability of the two materials,the drilling process of such laminated structures is prone to interfacial damage,including burrs,burning,chip accumulation,and inconsistent hole diameters at the interface.This damage significantly impacts the service life of the laminated structure.This paper provides a systematic review of interface damage during hole drilling in CFRP/alloy laminates.Regarding the machining characteristics at the laminate interface,the drilling process of laminated structure and the formation and evolution of chips,thrust force,and drilling temperature are described.Regarding the machining mechanism at the laminate interface,the drilling process and the formation and variation of chips,axial force,and drilling temperature are described.Concerning the formation of interface damage,the influencing factors based on the drilling mechanism of laminate hole formation are analyzed.Regarding interface damage suppression strategies,effective approaches are outlined from three perspectives:machining parameters,drilling tools,and machining methods.Finally,future research trends for suppressing interface damage during drilling of CFRP/alloy laminated materials are projected.
