Wind turbine blades are critical additives that at once influence the performance, reliability, and service lifestyles of wind strength systems. As turbine sizes increase to fulfill growing strength needs, the need for advanced substances with advanced mechanical and thermal houses becomes crucial. This look at affords a comprehensive finite element evaluation (FEA)-primarily based investigation into the structural and thermal overall performance of horizontal-axis wind turbine blades product of advanced composite substances, particularly epoxy-glass and epoxy-carbon. The blade geometry become modeled using Pro/ENGINEER (Creo Parametric), and static structural, modal, and consistent-state thermal analyses have been conducted the use of ANSYS Workbench beneath operational loading situations described by using worldwide requirements (IEC 61400-1). Simulation outcomes discovered that epoxy-carbon composite blades exhibited notably lower total deformation (729 mm) in comparison to epoxy-glass blades (955.33 mm), demonstrating enhanced stiffness and resistance to aerodynamic hundreds. Additionally, epoxy-carbon displayed marginally lower von Mises stress (10.51 MPa vs. 10.82 MPa) and extra uniform stress distribution, indicating stepped forward fatigue resistance. Directional deformations within the flap-smart (Y) and area-wise (Z) instructions had been additionally reduced via about 24% and 24%, respectively, inside the carbon-bolstered layout. Thermal evaluation showed that epoxy-carbon composites exhibited lower thermal growth and greater solid dimensional behavior below temperature gradients, a essential element for offshore and arid-climate deployments. These findings verify that epoxy-carbon composites offer advanced specific electricity, stiffness-to-weight ratio, and thermal stability over conventional epoxy-glass, making them tremendously appropriate for next-generation wind turbine blades notwithstanding better preliminary fees. The study underscores the effectiveness of included CAD/CAE workflows in accelerating blade design optimization and validating overall performance underneath multi-physical loads.
