Characterization and micro end milling of graphene nano platelet and carbon nanotube filled nanocomposites

Experimental investigation on micromachining of epoxy/graphene nano platelet nanocomposites

“…As the FPT increases, more and more pits are formed on the surface, gradually increasing the surface roughness. This phenomenon is consistent with the results of the previous machining experiments with plain polymer material [8].…”

“…This generates an increase in the total fracture surface area, resulting in the absorption of more energy and greater cutting force compared with plain epoxy [10]. Secondly, the overall strength and modulus of the epoxy/GNP nanocomposites are greater, because the rough and wrinkled surface texture of graphene enhances the mechanical interlocking/adhesion with the polymer matrix [8,[48][49][50].…”

“…Based on such superior properties, applications of GNP have attracted great attention [5][6][7]. Therefore, GNP has been experimentally added to various kinds of polymers such as epoxy, poly (styrene), poly (acrylonitrile) and poly (methyl methacrylate) matrices [7,8]. For example, PMMA/GNP 0.1 wt% nanocomposites can obtain a 33% improvement in Young's modulus compared with plain PMMA [7], and Epoxy/GNP 0.1 wt% nanocomposites can obtain a 31% Young's modulus greater compared with that of plain epoxy [8].…”

The results of other mechanical tests such as critical buckling load [9] and friction [10] tests have also demonstrated that the addition of GNP lead to considerable improvements in mechanical properties.…”

A review on the mechanical, electrical and EMI shielding properties of carbon nanotubes and graphene reinforced polycarbonate nanocomposites

“…The PC/OGnP/MWCNT composites having 1.5 to 5.0 phr loading of OGnP‐exhibited electrostatic discharge properties. Kumar et al studied thermal and mechanical properties of graphene nanoplatelet (GnP) and MWCNT‐filled PC nanocomposites fabricated through injection molding. The addition of GnPs and MWCNTs to the PC matrix decreased the yield strength and the elongation at the break of the nanocomposites, while an improvement of 10% to 16% in the elastic modulus was observed with the addition of 2 wt% GnPs and MWCNTs.…”
