In recent years, composite structures of polymers have been widely considered. Extensive applications for these composites have been widely recognized in various industries and sciences, which have greatly increased the studies in this field. In this study, the addition of SiO 2 nanoparticles into the PP / PET composite structure has been investigated. The viscosity value as a response parameter has been used to investigate the effect of SiO2 addition into the PP/PET matrix. The results of this study indicate that the addition of PET to the polymeric phase of the based PP increases the viscosity of the resulting polymer structure. Increasing the PET content also has a greater effect on viscosity increase. SiO 2 nanoparticles were used in sizes of 12 and 20 nm in a volume fraction of 5 and 9% by weight. As a result of empirical observations, an increase in viscosity was observed by increasing the volume fraction and reducing viscosity by increasing the size of the nanoparticles.
