In this study, PP-based composite reinforced with three pressures, three temperatures, three reinforcement rates, and three reinforcement sizes were produced and their Melt Flow Index (MFI) properties were investigated. Moreover, 0.2% maleic anhydride and fenolic based antioksidant in order to prevent oxidation were also added during addition of aluminum powders. According to the results of the study, MFI values degreases with increasing viscosity. On the contrary, MFI values increases with increasing shear rate and shear stress. In addition, values of 1379 kPa, 250 C, 5%, 210-300 mu m and 44-100 mu m were determined as pressure, temperature, reinforcement ratio and particle size respectively for the samples having high MFI values.
