EXPERIMENTAL STUDY AND SIMULATION BY METAHEURISTIC ALGORITHM OF THE DAMAGE OF BIO-COMPOSITE MATERIALS

Abstract

This present work is focused on the elaboration of different types of biocomposites by recycling the waste plastic bottle caps made of high-density polyethylene (HD-PE) and using it as a matrix reinforced with Alfa fibers and Pozzolan powder, followed by a mechanical and morphological characterization. Furthermore, a numerical investigation was pursued to develop an analytical model based on a genetic approach, using the Weibull model, to study the effect of damage to the fibre-matrix interface of four biocomposite materials based on polylactic acid (PLA) reinforced with three types of natural fibres raffia, alfa, and sisal fibres. The experimental results are in good agreement with the numerical investigation. indicate that natural fibers-based composite materials can represent a good potential in improving interfacial properties. The study shows an alternative for producing friendly biodegradable composites that can be a solution for plastic waste reduction and a substitute for petrochemicalderived products.
