Wind Energy Composites

Composite materials for wind turbine blade manufacturing

Wind turbine blade manufacturing demands materials that deliver exceptional fatigue resistance, low void content, and long-term durability in harsh outdoor environments. Epoxy infusion resins are the industry standard for blade shells and spar caps, chosen for their superior mechanical properties, low shrinkage, and compatibility with vacuum infusion (VARI) and prepreg processes. UPR remains common in smaller blades and nacelle components where cost efficiency is critical.
