Abstract:In this paper, the preparation and casting of sample composite, machining parameters and Scanning electron microscopy (SEM) studies on multi-walled carbon nanotubes (MWCNT) reinforced epoxy composites were discussed. Structurally, MWCNTs consist of multiple layers of graphite superimposed and rolled in on themselves to form a tubular shape. Three properties of MWCNTs are specifically interesting for the industry which are the electrical conductivity (as conductive as copper), their mechanical properties such as strength (up to 15 to 20 times stronger than steel and 5 times lighter) and their thermal conductivity (same as that diamond and more than 5 times that of copper). Dispersion of MWCNTs’ with epoxy resin were achieved using magnetic stirrer. MWCNT/epoxy composite was cured at 50 0C for four hours to form a Rigid MWCNT/epoxy composite. The effect of machining parameters on MWCNT/epoxy composite displays different surface morphology under SEM with control of 3 major parameters of spindle speed, feed rate and depth of cut. Taguchi and ANOVA method are implemented for statistical analysis and obtained the most dominant factor that affects the surface quality.
