Wind energy

For many years, we have been supplying our wind energy customers with textile reinforcement materials for increasingly longer rotor blades and larger wind turbines. This enhances efficiency and simplifies transportation to areas that are difficult to access, such as offshore wind farms on high seas, where our products can withstand even the most hostile of environmental conditions. Our multiaxial fabrics made of glass and carbon fibers reinforce the webs, spar caps and shells of wind turbine rotor blades. Very high mechanical forces act in the area of the blade connections in particular, which our NCF materials can withstand.

To meet the increasing requirements for stiffness, design and cost competitiveness of rotor blades with lengths of up to 140 meters, we use many new material developments from SAERTEX in addition to the proven unidirectional fabrics made of E-Glass:

  • H-modulus glass fiber: new fiber types especially for use in spar caps
  • Hybrid fabric structures made from glass and carbon fibers
  • SAERfix: Self-adhesive NCFs that replace spray can adhesives
  • SAERfoam for wind: Structural core material for sandwich constructions in shells and spars
  • Easy Drape UD: Unidirectional fabrics for wrinkle-free draping and a 20% improvement in tensile strength
  • Magic Flow UD: Optimized flow materials for improved resin infusion for up to 200 layers
  • Steady Plus UD: Carbon UD with excellent values and the potential to reduce your resin consumption

Reinforcing Spar Caps in Rotor Blades

In addition to our standard and special function fabrics, we also offer the wind industry services such as cutting & kitting, prototyping and GL certified laboratory testing. SAERTEX is a long-standing partner to the wind industry and works closely with customers worldwide to develop lightweight materials that enable the production of more efficient wind turbines. Our international network includes production and service locations on almost every continent to ensure local availability.

Wind turbines play a crucial role in the use of renewable energy and therefore fit perfectly with our vision of "Innovation for a resource saving future”. But what happens when their blades need to be repaired? Our step-by-step guide shows you how to repair rotor blades effectively: HOW TO

three good reasons

  1. Sales of >100,000t glass and carbon per annum are good indicators of the highest performance and availability of our products.
  2. Our non-crimp fabrics and core materials are certified to GL standards, as is our in-house materials testing laboratory in Saerbeck.
  3. Our team of application engineers, with experience in a wide range of different wind energy projects, is on hand to provide a high quality consulting service.
