Development of Bio-Composite Blades for Straight Darrieus Wind Turbines

Abstract

In the present modernized world, with the increase in energy demand, conventional energy sources are not only towards the depletion stage but also causing serious adverse effects on the environment. The escalating environmental concerns and the urgent need for sustainable energy solutions have intensified the quest for renewable energy sources. Among the various renewable sources, wind is the most viable and practical form, generating a large amount of usable electricity. However, the conventional materials used in the construction of wind turbine blades such as glass/carbon fiber reinforced polymers (FRPs) have raised serious environmental concerns due to their non-biodegradable nature and reliance on fossil fuels during manufacturing. To address these challenges, the development of bio-composite materials represents an environmentally friendly alternative for wind turbine blades. These composites possess several advantages over conventional composites, including a low carbon footprint, better recyclability, and possible improved mechanical properties.
