HOW TO REPAIR A WIND BLADE


Wind turbines are crucial for the generation of renewable energy. But what happens when the rotor blades need to be repaired?

HOW TO REPAIR A WIND BLADE

SAERfoam for Wind

While the demand for renewable energy is rising, the scarcity of balsa core materials threatens progress. 
Therefore, our goal is to replace these conventional materials with engineered foams like our SAERfoam for Wind.

VAP® infusion-moulded carbon fibre spar caps

PAN-based carbon fibres with a high carbonization degree (>99%) and their industrial production process were first developed in the 1960s. VAP<sup>®</sup> infusion-moulded carbon fibre spar caps

Fire-retardant Composite Panel for Shipbuilding

Fiber-reinforced composite materials are rarely used in cruise or merchant ships for fire safety reasons. Saertex has now developed a fire-retardant standard panel and worked additionaly with the Meyer Group to incorporate the composite into a sandwich construction for the sun deck and exterior walls of a river cruise ship, achieving a 45 % weight saving.

INDUSTRIALIZED MANUFACTURING OF CFRP REINFORCEMENT PROFILES

The current method of manufacturing composite structures, especially in aviation, is characterized by a variety of manual and semi-automated production processes. In order to satisfy the demand for an increased production rate in a manner that conserves resources and is cost-effective, while also taking into account a wide range of variants, novel automated technologies for the production of frames have been developed during the KOLIPRI project.

Large-scale preforming – innovative approach in the production of rotor blades

In order to meet the demand for shorter cycle times and higher quality demands of the growing fiber-plastic composite parts (FRP), the Institut für integrierte Produktentwicklung (BIK) of the University of Bremen, the producer of non-crimp fabrics, the SAERTEX GmbH & Co. KG and the rotor blade manufacturer AREVA Blades GmbH developed new manufacturing technologies and automation-enabled materials.
