Blending and injection molded wood polymer composites using morus alba fibers and hdpe: A study on physical, mechanical, and termite resistance properties and morphology

The growing impact of global warming and deforestation has increased the demand for sustainable alternatives to traditional wood based materials. This study examines Morus alba (silk mulberry) wood particles as a renewable reinforcement in high density polyethylene (HDPE) composites. Composites were produced through melt blending and injection molding with varying particle loadings. Mechanical, physical, termiteresistance, and morphological properties were evaluated. Results showed that incorporating silk mulberry particles enhanced tensile and flexural strength, density, and durability up to an optimal reinforcement level. Morphological analysis confirmed good particle dispersion and interfacial bonding. These findings demonstrate the potential of silk mulberry agricultural waste for developing eco-friendly polymer composites and supporting sustainable material innovation.1
