Description
Summary:This present research aims to predict the mechanical behavior of the composite and hybrid composites based on a polypropylene matrix (PP) reinforced by organic/inorganic naturally occurring fillers using analytical and numerical models. It also aims to demonstrate the effect of hybridization on the global stiffness of the material. In this study, Voigt-Reuss models, Halpin-Tsai equations, the Hirsch model, and numerical simulation are applied to predict the effective elastic moduli of hybrid composites/composites with clay and other alfa fillers. The results obtained are compared with experimental data. Hirsch’s results match well with the experimental results for the alfa/PP composite. However, the values of the Halpin-Tsai model showed a good agreement with the experimental results for the alfa-clay/PP hybrid composite. The numerical results show good accordance with the experimental results with higher accuracy. The overall results provided a good indication of the effects of hybridization on the stiffness of the final hybrid composites.
