Fabrication and Mechanical Feasibility of Fan Blade Using Alkaline Treated Hybrid Enset-Bamboo Fiber Reinforced Polyester Composite

This study explores the development of eco-friendly, high-performance fan blades using a hybrid composite of Enset and Bamboo fibers reinforced with unsaturated polyester resin. To improve mechanical interlocking, fibers underwent alkaline (NaOH) treatment, and an optimal composition of 25% Enset, 20% Bamboo, and 55% polyester was determined through systematic analysis. The resulting composite blades achieved excellent durability, exhibited a low water absorption rate of 1.38%, and offered a significant 31% weight reduction compared to traditional aluminum alternatives, demonstrating their viability for aerodynamic applications.
