Epoxy Resin For Wind Turbine Blade Manufacturing


Wind turbine blades represent a large-scale application of composites, but they are often discussed separately due to their volume and processing requirements. Epoxy resin performs exceptionally well in large blade infusion.

Viscosity is controlled between 200 and 400 mPa·s, with a working time exceeding two hours, ensuring that blades longer than 60 meters are free of dry spots or voids. Fatigue strength is excellent, with modulus retention exceeding 90% after one million fatigue cycles, meeting a 20-year service life.

The material also resists humidity, heat, and salt spray, achieving ISO 12944 C5-M corrosion protection for offshore blades and nacelles. It offers good interfacial bonding with glass or carbon fibers, with interlaminar shear strength exceeding 50 MPa.

Typical products include blade matrix resins, blade structural adhesives, and mold resins.
