Senvion has bought Rodpack technology from Chase Corporation.
The technology is already used in the Senvion 6.2M152 and is expected to be used in future onshore and offshore turbine blade designs.
The Rodpack technology works by substituting glass fabrics used in the main girder, enabling better blade design and faster and higher quality blade production.
Senvion is working on the co-development of a machine which will expand the Rodpack production capacity and the technology will be exclusively available and used in Senvion turbines.
Senvion chief executive Andreas Nauen said: “The steady improvement of our turbines and their efficiency is key for us. It is our aspiration to use the best and highest-quality materials and products on the market. The acquisition of RodPack is a logical step for us to reach that goal.”
RodPack has 9% better material properties than high-modulus glass and 20% better than standard unidirectional glass. This creates the potential for blade designs with higher yields, longer life or a higher wind class.
Senvion vice president Bernhard Telgmann said: “Earlier this year, we announced that together with our new owner we would be able to strengthen the investment in our product development. Since then, we have presented a new turbine with the longest onshore blades currently available and are now going a big step forward in the efficiency improvement of blades by acquiring RodPack.
