Carpets, comprising a textile floor covering featuring a pile affixed to a backing, typically consist of fibers, either natural, synthetic, or a combination thereof, forming the visible surface or pile. In the current study, WTB utilizing the NACA 2415 aerofoil type is made from a composite material resulting from recycled carpet waste. The composite material incorporates banana + hemp + glass fiber fabricated by the hand layup method. A comprehensive analysis of the tensile, flexural, and impact strengths is conducted, revealing significant enhancements in mechanical properties upon the integration of banana + hemp fibers into the glass fiber matrix. The conclusions drawn from this study are based on the performance evaluation of a vertical axis wind turbine (VAWT) equipped with hybrid composite material blades incorporating a modified aerofoil design to enhance lift. Parameters derived from experimental results indicate that optimizing the wind turbine’s actual power output occurs with increased tower height and inlet velocity when utilizing blades with a smooth surface. These findings underscore the efficacy of employing hybrid composite materials and aerodynamic modifications to enhance wind turbine performance.
