Sustainable Materials Engineering: Development, Characterization, and Environmental Impact Assessment of Green Composite Materials

Abstract

The increasing demand for sustainable development has intensified research efforts toward environmentally responsible materials in engineering applications. Conventional composite materials, although offering excellent mechanical performance, pose significant environmental challenges due to their dependence on non-renewable resources and poor end-of-life disposal characteristics. Green composite materials, developed using natural fibers, bio-based resins, and recyclable matrices, present a promising alternative for sustainable materials engineering. This paper investigates the development, characterization, and environmental impact assessment of green composite materials for structural and non-structural engineering applications. The study examines material selection strategies, fabrication techniques, and mechanical, thermal, and durability properties of green composites. Emphasis is placed on life cycle assessment to evaluate environmental benefits in comparison with conventional composites. Experimental characterization is supported by analytical modeling to assess performance reliability. The paper also discusses challenges related to moisture absorption, interfacial bonding, and large-scale manufacturing. Results indicate that green composites demonstrate competitive performance while significantly reducing environmental impact. The findings support the adoption of green composites as viable materials for sustainable engineering systems.
