In this study, basalt fiber reinforced plastic (BFRP) wind turbine blade was
analyzed and compared with glass fiber reinforced plastic blade (GFRP).
Finite element analysis (FEA) of blade was carried out using ANSYS.Data for FEA was obtained by using rule of mixture. The shell element in ANSYS was used to simulate the wind turbine blade and to conduct its strength analysis. The structural analysis and comparison of blade deformations proved that BFRP wind turbine blade has better strength compared to GFRP wind turbine blade.
Structural analysis of BFRP and GFRP wind turbine blade has been performed. FEA model results achieved using ANSYS have confirmed the better strength and stiffness of BFRP wind turbine blade.
This analysis showed that the deflection and stress developed in BFRP blades were less as compared to GFRP blade in same force condition, thickness and boundary condition. From this analysis it can be concluded that
- Basalt fiber has better strength and stiffness than glass fiber.
- Basalt fiber for their wide range of good mechanical properties offers an interesting economic alternative for modern wind turbine blades.
However prior to the implementation of basalt fiber as the new composite material for wind turbine blades, experimental investigation is needed, especially when dealing with their fatigue behavior in order to utilize the benefits associated with the material.
