DETERMINATION OF THE RHEOLOGICAL PROPERTIES OF HYDROXYL TERMINATED POLYBUTADIENE (HTPB) MIXTURES WITH ENERGETIC MATERIALS AND PRESENTING EMPRICIAL MODELS

Rheological properties such as viscosity (11), shear stress ('r), and torque (m)of the mixtures of (htpb) with octagon (hmx), hexogen (rdx), and 2,6 diamino-4phenyl-i, 3,5 triazine (dapta) mixtures were measured. the experimental design wasarranged for three factors at two levels (high and low levels). temperature of the mixture(c), speed of the stirrer (rpm), mixing tinle (nlinutes) have been known to be effective inthe quantity of rheological properties. in this work, by using the appropriate equations theempirical model was presented for each property and mixture and the nlain effects on theresponses were detected.
