In a significant stride towards sustainable materials, researchers have developed a novel composite that could revolutionize industries from packaging to automotive and construction. The study, led by Md. Syduzzaman from the Department of Textile Engineering Management, explores the potential of hybrid jute and banana fiber-reinforced recycled high-density polyethylene (rHDPE) composites, offering a greener alternative with enhanced mechanical properties.
The research, published in the journal ‘Advances in Polymer Technology’ (translated as ‘Advances in Plastic Technology’), addresses the dual challenge of improving both flexural and impact properties while maintaining structural integrity. By employing a unique (0°/90°/0°/90°) stacking configuration and plasma treatment, the team achieved remarkable results. “Plasma treatment drastically influenced the adhesion between the fiber and matrix,” explains Syduzzaman, leading to a 45.4% improvement in impact strength for the plasma-treated hybrid composite compared to its untreated counterpart.
The plasma-treated hybrid composite, dubbed PJBC, demonstrated an impressive impact strength of 31.86 kJ/m² and a flexural strain of 7.6%, indicating superior energy dissipation and ductility. While the flexural strength saw a slight decrease due to increased surface brittleness, the overall benefits of plasma treatment and hybridization proved substantial. The treatment also improved water absorption in jute composites, but hybridization helped balance this effect, yielding composites with optimal mechanical properties and moisture resistance.
The synergistic combination of jute’s stiffness and banana’s flexibility, enhanced by plasma-induced surface activation, resulted in composites with exceptional structural integrity and sustainability. “This research demonstrates the viability of plasma-treated hybrid rHDPE composites for resource-efficient applications,” says Syduzzaman, highlighting their potential in various sectors, including the energy sector, where sustainable and durable materials are in high demand.
The findings pave the way for future developments in eco-friendly materials, aligning with the goals of the circular economy. As industries increasingly seek sustainable alternatives, this research offers a promising solution that could shape the future of material science and engineering. The study not only advances our understanding of composite materials but also underscores the importance of innovative treatments like plasma processing in enhancing material performance. With further research and development, these hybrid composites could become a cornerstone of sustainable practices across multiple industries.
