Wind energy

For many years we have been supplying our wind energy customers with reinforcing materials for increasingly longer rotor blades and larger wind turbines. On the one hand, this allows the efficiency of the turbines to be increased, while on the other the lightweight construction facilitates transportation of turbine components to areas that are difficult to access – for instance when developing offshore wind farms on the high seas. In such situations our products can withstand even the most hostile of environmental conditions.

Our fabrics made of glass and carbon are used to 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, and our materials must be able to withstand these stresses. For the area of the blade connections we supply glass and carbon fabrics for monolithic construction. Our special functional fabrics SAERfix and 3D fabrics are particularly suited for such applications. Self-adhesive SAERfix fabrics mean that spray adhesives become a thing of the past, while 3D fabrics provide an excellent alternative to standard fabrics – particularly when it comes to the production of thicker components. For shells and spars our structural core material SAERfoam is seeing increasingly use in sandwich construction, alongside multiaxial interlaid complexes. In the area of spars, UD carbon fabrics are seeing increasing use alongside UD glass fabrics, in order to facilitate even longer rotor blade spans.

In addition to our standard and special functional fabrics, we also offer the wind energy sector services such as cutting & kitting, prototyping, GL-certified laboratory testing and – in particular – our complete component manufacturing service in Stade.

SAERTEX has been part of this rapidly growing industry right from the very beginning. Our close cooperation with customers enabled us to develop lightweight construction materials that allow ever more efficient wind turbines to be produced. All around the world, manufacturers in the wind energy industry are experiencing a renaissance – just like SAERTEX. Because we have grown along with our customers and branched out into international markets. We now have production and service operations in 8 countries on 5 continents.

In 2014 SAERTEX received the prestigious JEC Innovation Award in the wind power sector for the MAPRETEC project. This award recognised our contribution to the automation of rotor blade manufacture in cooperation with the University of Bremen and AREVA Blades.

Current SAERTEX-News about the wind energy industry:

 

three good reasons

  1. Sales of 95,000t glass and 1,500t carbon per annum are good indicators of the highest performance and availability of our products.
  2. Our fabrics and core materials are certified to GL standards, as is our in-house materials testing laboratory in Saerbeck.
  3. Our team of industry specialists and application engineers, with experience in a wide range of different wind energy projects, is on hand to provide a high quality consulting service.
