This study explores the feasibility of a single-stage processing technique for the production of natural fiber-reinforced thermoplastic composites by integrating extrusion with compression molding. The primary objective is to streamline the manufacturing process while improving the mechanical and thermal properties of the resulting composites. Natural fibers such as jute, hemp, and flax are combined with thermoplastic matrices like polypropylene and polyethylene in a one-step extrusion process, followed immediately by compression molding. This method offers potential advantages in terms of reduced energy consumption, lower processing times, and cost-effectiveness compared to conventional multi-stage processes. To evaluate the performance of the composites, a comprehensive analysis of mechanical properties (tensile strength, flexural strength, impact resistance), thermal properties (thermal stability, heat deflection temperature), and water absorption characteristics is conducted. Additionally, the fiber-matrix interface is optimized through surface treatments and fiber content adjustments to enhance interfacial bonding. The results indicate that single-stage processing can produce high-performance natural fiber-reinforced thermoplastics with improved material properties, paving the way for their use in sustainable engineering applications. The findings also suggest that with proper optimization of processing parameters and fiber treatments, the composites exhibit enhanced mechanical strength, making them suitable for various industrial applications.
