Evaluation of Mechanical and Physical Properties of Hybrid Composites from Food Packaging and Textiles Wastes

Abstract

In the present work,hybrid composites were designed by using shredded Tetra Pak packages as food packaging wastes and wool yarn wastes as textiles wastes for potential alternative construction and building materials. Hybrid composites were fabricated by mixing different ratios (0, 5, 10, 15 and 20wt%) of wool yarn wastes with shredded Tetra Pak wastes. Mechanical properties in terms offlexural, tensile strength, internal bonding (IB) in addition to the impact properties and physical properties in terms of thickness swelling (TS), water absorption (WA) and density of the fabricated composites were analyzed and compared with the properties of commercial wood particleboards. Results showed that when the ratios of wool yarn wastes increased to 15% in hybrid composites, modulus of rupture value reached 15.10 +/- 1.01MPa which is higher than that of particleboards (types P2, P4, and P6 as per the British StandardsBS). The highest IB strength was found to be 0.60MPa for the hybrid composites with 10% wool yarn content, while IB values of the other samples reduced with increasing the amount of wool yarn wastes. Moreover, TS and WA of the fabricated hybrid composites were found to be better than commercial particleboards and they also encountered the minimum strength requirements in BS. Overall, we concluded that the developed hybrid composites from agro-industrial waste materials could be utilized as promising alternative source of raw materials to manufacture value added eco-friendly, advanced and sustainable structural applications such as wood panels.
