Experimental and numerical study of the mechanical behavior of bio-loaded PVC subjected to aging

Abstract

Increased recycling of PVC has become a requirement in industrial and scientific research level. Several studies will be realized. To confirm and check the recycled materials performance, it will be important to go through numerical modeling, which consists not only in validating the results of the experiments, but also in predicting what happens when the material is loaded. PVC material is more used in different fields, that ultimately means, after service life, an increase in waste requiring a high recycling rate. This article presents an approach validating the aging model as well as a numerical analysis predicting the mechanical properties of PVC after aging. The analysis samples (rigid and flexible) PVC which are subject to two types of accelerated aging, allows to obtain an aging model. Numerical modeling of PVC after aging is carried out using the finite element method and has been able to confirm the results obtained experimentally. Predicting the mechanical properties of rigid PVC after aging loaded with coconut and cow horn fibers after a first recycling is made by the finite element method, Mori-Tanaka and Double inclusion models. The obtained results have showed an improvement in the mechanical characteristics of the PVC studied using this natural bio-loading with these two fibers which respect the environment and have a lower cost and more lightness.
