6 FAQs about [Material requirements for generator rotor blades]

What materials are used for wind turbine blades?

What is a rotor blade standard?

This standard is applicable to the structural and functional design, and manufacturing, of rotor blades for wind turbines, including requirements for materials, testing, repair and operation.

What are the requirements for rotor blades?

Depending on the scheme, the requirements for the design and manufacture of rotor blades are defined by one of the following standards and guidelines: GL 2010 , DNVGL-ST-0376 or IEC 61400-5 . What these fundamentally have in common is that they are based on the Limit-State-Design concept, see Sect. 2.2.

How are composite materials tested for wind turbine rotor blades?

At the macroscale, materials testing of composite materials for wind turbine rotor blades involves both static and cyclic loads, testing of the base materials (usually unidirectional layers), laminates, sandwich core materials, adhesives, gelcoats and interfaces between various layers.

What are the requirements for manufacturing wind turbine blades?

If standard repairs are part of a certification, the requirements of Sec.8 shall apply, and shall be verified as part of a manufacturing evaluation. The manufacturing of wind turbine blades shall be carried out according to appropriate documentation, at least including approved work instructions, drawings, and quality procedures.

What is a rotor blade in a wind turbine?

The rotor blade is the key component of a wind turbine generator (WTG) and converts the energy of the wind into a mechanically useful form of energy. It represents a significant cost factor in the overall context of the turbine and at the same time has an enormous impact on the yield of the turbine.
