Eco-Friendly Polymer Composites Using Chemically Modified Natural Fibers

The increasing awareness of environmental protection and sustainability has led to the development of natural fiber-reinforced polymer composites as alternatives to conventional synthetic materials. These composites offer renewability, biodegradability, and cost-effectiveness. However, poor fiber–matrix adhesion limits their mechanical performance. This study focuses on developing eco-friendly polymer composites reinforced with chemically modified natural fibers such as jute, sisal, and banana. Alkali and silane treatments were used to enhance fiber surface characteristics. Mechanical, thermal, and morphological analyses revealed that chemical modification significantly improves tensile and flexural properties, thermal stability, and water resistance. The results demonstrate the potential of these composites in sustainable engineering applications such as automotive, packaging, and construction industries.
