Nd–YAG laser machining of SiC fibre/borosilicate glass composites. Part II. The effect of process variables

The path towards delamination-free drilling of composite materials

“…The type and pressure of the assistant gas, the focal depth of spot and the cutting speed with 400 W Nd:YAG laser determined the drilling performance, such as the hole depth and induced damage in a silicon carbide fiber-reinforced material [109]. Rodden et al studied the long-pulse Nd:YAG laser drilling of multi-layer carbon fiber composites [110].…”

Laser beam machining—A review

“…Nd:YAG laser drilling of fibre-glass composites (7 mm thick) show that setting of focal plane position w.r.t. workpiece surface for minimum hole taper depends on material thickness [78]. CO 2 and Nd:YAG laser drilling of polyester foils and glass fibre reinforced epoxy laminates give larger hole diameter at increased laser power [79].…”

Experimental study of Nd:YAG laser beam machining—An overview

“…Also the flexural strength of cut specimen was found to be reduced by 40%. Pulsed Nd:YAG laser cutting of glass-matrix composite (GMC) was experimentally investigated by Tuersley et al (1998). Their findings show that the use of oxygen is to be avoided owing to oxidation of molten matrix glass, but use of nitrogen can remove the problem of oxidation.…”
