Abstract

ABSTRACT: In this work, the influence of compatibilization, blend composition and processing parameters on the rheological, morphological and mechanical properties were studied for blends of polypropylene with aromatic polyamide with glass fibers obtained by injection molding. It was shown that the compatibilizer improves the adhesion at the interface, emulsifies and stabilizes the morphology. Using rheological data obtained with an in-line rheometer, localized in the injection molding machine and morphological observations, it was shown that significant evolution of phase structure occurred depending on processing or compounding parameters. Also, the orientation of the glass fibers was studied as a function of the position in the mold cavity, showing the presence of three layers of different morphology in the molding. (AU)
