1. Introduction
Wind energy represents a significant source of renewable energy, contributing to the global shift towards sustainable power generation. As countries strive to reduce their reliance on fossil fuels, the demand for efficient and reliable wind energy systems has surged. The efficiency of these systems largely depends on the materials used in turbine construction. Advanced materials, such as composites and nanomaterial’s, have the potential to enhance mechanical properties, reduce weight, and improve the energy conversion efficiency of wind turbines.
The construction of wind turbine blades is particularly critical, as they are the most significant components influencing the turbine’s overall performance. Traditionally, wind turbine blades have been made from fiberglass-reinforced composites, which offer a good balance of strength and weight. However, the increasing size of modern turbines necessitates materials that can withstand greater mechanical stresses while minimizing weight. For instance, carbon fiber composites are being explored for their superior strength to weight ratio, leading to lighter blades without compromising durability
