Rheological histeresis of lled starch during rotational shearing has been studied in this study. The ller concentration was varied from zero to high levels. Temperature during shear is varied to observe the thermal structure variation of starch. The e ect of ller concentration, temperature e ect, shear rate e ect and elongation e ects on the rheological behavior are experimentally studied with rota- tional viscometer. Several rheological models are used to describe the non-Newtonian behaviors of lled starch under various thermal conditions. The model predictions are compared with rheological data from our experiments. |
