Physical and Mechanical Properties of Polymer Composite Materials Based on Olive Husk Flour
The lack of compatibility between cellulose fibers and some polymers, such as thermoplastics, is due on one hand to the hydrophilic nature of the vegetable fibers and on the other hand to the hydrophobic character of the matrix. This incompatibility induces bad dispersion of the fibers and the formation of a heterogeneous material with mechanical properties which are not very satisfactory. The scope of this article is to describe the possibility of using Olive Husk Flour (OHF) as reinforcement in the elaboration of a composite material based on polyvinyl chloride (PVC). In this context, we used the PVC-g-MA as compatibilizer and investigated the effect of the loading and the effect of treatment on the mechanical properties and thermal behavior of these composites; the structures have also been characterized by scanning electron microscopy (SEM) and X-ray diffraction analysis (XRD).
