Wind turbine blade materials

Wind speeds up to 90 km/h, blade tip speeds up to 300 km/h, strong UV-radiation and weather: Wind turbine blades are permanently exposed to high stress. In development, constructors must make many decisions, from the blade type to the structure and design. We support you in production with high-performing materials: We offer a great selection of composite and thermoplastic materials that are, e.g., mechanically highly resilient, UV-resistant or very form-stable. You can construct high-performance wind turbine blades with a long service life.

Your advantages

  • Noise reduction of wind turbine blades
  • High mechanical resilience
  • Long service life: UV and weather resilient
  • Low-maintenance

Typical areas of application

  • Onshore wind turbines
  • Offshore wind turbines
  • Small wind turbines

Product examples

Trailing edge serrations

Trailing edge serrations machined from our glass fibre-reinforced material Durostone® offer high mechanical resilience, are UV-resistant and contribute to noise-optimised and efficient function of wind turbines. More about Durostone®

Pultruded profiles for rotor blade spar caps made of GFRP and CFRP

Pultruded profiles for rotor blade spar caps made of our carbon fibre-reinforced or glass fibre-reinforced Durostone® increase strength of rotor blades and thus contribute to longevity and reliability.

Gear wheels for rotor blade adjustment

Gear wheels machined of SUSTAMID 6 nature (PA) for rotor blade adjustment are wear-resistant, offer a high mechanical resilience and are resistant against lubricants. They permit simple reinforcement of the rotor blades for efficient conversion of wind power into energy. More on SUSTAMID 6 natural (PA)

Rotor blades for small wind turbines

Rotor blades pultruded of Durostone® for small wind turbines have outstanding mechanical properties thanks to their special glassfibre reinforcement with triaxial meshes and fabrics, which makes them particularly long-lived and resilient. More about Durostone®-Profiles

Arrange technical advice

The performance and reliability of materials for wind turbine blades are influenced by a variety of factors. These criteria need to be considered in order to make the right choice. Examples:

  • Wind speed
  • Blade tip speed
  • Mechanical influences
  • UV-radiation and weather
  • Contact with corrosive salt water
  • Constructional requirements, dimensions and tolerances
