Experimental investigation of multi-wall carbon nanotube added epoxy resin on the EDM performance of epoxy/carbon fiber/MWCNT hybrid composites

In this study, the effect of multi-wall carbon nanotube (MWCNT) on machining damages and material removal mechanisms in electro-discharge machining (EDM) of carbon fiber reinforced epoxy resin (CFRE) was evaluated. Field-emission scanning electron microscopy (FE-SEM) was used to investigate the machined surface morphology and elemental analysis. The effect of MWCNT content, pulse current, and pulse-on time was investigated on machining damages...
