The mineral filler increases si gnificantly in rheological parameters, whatever it nature of th e mineral filler. Compared to the control without charges, an increase of 60% of the shear stress and that of plastic viscosity were reco rded for the epoxy resin. The software Rheowine viscometer enabled us to m odel and identified the rheological behavior of these mixtures wit h resin. The results obtained in this modeling, confirmed that th e resin mixtures have shear-thinn ing rheological behavior, this last allows the model of the Ostwald de WaeleenComposite materialsMineral fillersRheologyShear rateShear stressArticle
