Description
Summary:The study is to synthesize composite materials with news formulations of thermosetting matrices by the incorporation of 40% of mineral fillers to reduce the cost of composite materials and to improve implementation by increasing the viscosity and reducing the withdrawal to its minimum value. The mineral filler increases significantly in theological parameters, whatever it nature of the mineral filler. Compared to the control without charges, an increase of 60% of the shear stress and that of plastic viscosity were recorded for the epoxy resin. The software Rheowine viscometer enabled us to model and identified the rheological behavior of these mixtures with resin. The results obtained in this modeling, confirmed that the resin mixtures have shear-thinning rheological behavior, this last allows the model of the Ostwald de Waele.
