An investigation on optimization of parameters for injection molded Polypropylene-marble composites with Multi Objective Genetic Algorithm

摘要

In the era of sustainability, recycling of industrial waste material by using marble powder as filler in the Polypropylene matrix recommend an interesting opportunity. In this study, composites were fabricated by adding different weight percentages of marble powder (5-15 wt.%) in the Polypropylene by injection molding process. To evaluate the contribution of marble powder in the PP-marble composite, Mechanical characterizations such as Shore hardness test, compressive strength and impact strength were performed. For surface morphological characterizations Scanning Electron Microscopy (SEM) was performed for the Polypropylene-marble composites. Taguchi technique and Multi Objective Genetic Algorithm were used to optimize the parameters.
