Effect of physical treatment on the performance of thermoplastic matrix composites with natural fillers

Abstract

Date stone flour was, valorized for use as a reinforcement in the manufacture of polyvinyl chloride matrix composites. Gamma irradiation was, used to improve PVC/FND interfacial adhesion. A reduction in the hydrophilic character of the filler after treatment was, demonstrated by the decrease in the water absorption rate of irradiated DSF -reinforced composites, and this was, confirmed by the good dispersion of the treated filler in the matrix, observed by optical microscopy. As a result, better mechanical properties were, obtained.
