Viscosity of CNT Loaded Epoxy Resin
Science Research Association (SCIREA) Journal of Materials
The processing of fibre reinforced carbon nanotube (CNT) loaded polymer composites (nanocomposites) requires that CNTs be mixed (or loaded) into the polymer prior to impregnating the fibres to fabricate a nanocomposite. The fabrication process uses vacuum-assisted resin transfer moulding (VARTM), which is complicated due to the increase in viscosity of CNT loaded resin. The goal of this paper is to experimentally characterize the viscosity of a CNT loaded epoxy resin, with different weight percentages and shear rates. The maximum viscosities measured for the samples were: 800 cP for 0.2 %wt., 750 cP for 0.4%wt., and 890 cP for 0.6 %wt. All samples exhibited shear thinning behaviour as the viscosity decreased with increased shear rates.
