Recycled Polyethylene Composites Reinforced with Jute Fabric from Sackcloth: Part II-Impact Strength Evaluation

Environmental problems are motivating recycling actions and reuse alternatives for materials with main focus for the application of those renewable and biodegradable materials such as lignocellulosic fibers. Composites reinforced with such fibers are being considered by several industrial sectors, not only from the environmental safety, but also from economic considerations and improved properties. This paper, which is continuation of the work (Part I) by the authors’ use of the recycled polyethylene and used jute fabrics, presents evaluation of its toughness measured by the impact energy using both Izod and Charpy methods. Fabric content used is up to 40 wt. %. It is found that the incorporation of both types (new and used) of jute fabric significantly increased the impact energy of composites, with higher values associated with the new jute fabric. Fractographic analysis revealed that weaved configuration of the jute fibers and their low interfacial resistance with the matrix are responsible for the observed impact performance of these composites.
