Abstract
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.
