Pontis Engineering Introduces Welding Solution for Epoxy Blades

Pontis Engineering presented a welding technology for epoxy composite wind turbine rotor blades at WindEnergy Hamburg 2018. Enabling the welding of epoxy blades using thermoplastic resin, this technology is said to bring benefits in blade cycle time, weight and strength.

Two years ago Pontis introduced a welding solution for fully thermoplastic blades. The company has now developed a welding solution that can be used in existing epoxy designs in which prefab thermoplastic welding units are implemented in the epoxy shell. These units enable a welded connection, as well as a sharper trailing edge and a more compact connection.

In conventional rotor blade production bonding paste is commonly used. Pontis applied its new construction method to a test blade component and found a number of advantages, including:

  • increased reliability;
  • reduced cycle time for bonding operation (up to 90%);
  • reduced total workload (approx. 5%);
  • increased bond strength;
  • reduced blade mass (approx. 3-5%).

“Our mission is to support and guide our wind customers in their ongoing quest for smarter, more sustainable ways to produce even larger rotor blades with superior quality,” Pontis Engineering Director, Sjef van Breugel, says. “I am convinced that we can help them take a significant step further with this technology.”

Pontis Engineering is headquartered in Amsterdam, the Netherlands, with offices in China and the US.
