How does the inclusion of natural fibers other than wood (e.g., hemp, jute) affect WPC properties?

The inclusion of natural fibers such as hemp and jute in Wood-Plastic Composites (WPC) significantly influences their mechanical, thermal, and environmental properties. These fibers offer several advantages, including improved tensile strength, reduced weight, and enhanced biodegradability compared to traditional wood-based WPC. Hemp fibers, known for their high cellulose content, contribute to better stiffness and durability, while jute fibers provide excellent moisture resistance and flexibility. Additionally, natural fibers enhance the sustainability of WPC by reducing reliance on synthetic materials and lowering the carbon footprint. However, challenges like fiber-matrix adhesion and moisture absorption must be addressed to optimize performance. Overall, incorporating hemp, jute, or other natural fibers can lead to more eco-friendly and high-performance WPC products.
