9th International Conference Advances in Rotor Blades for Wind Turbines

21.-23. April, 2020
|Hamburg 

Workshop Day

7:45 am - 8:15 am Registration and welcome coffee

8:30 am - 11:00 am Workshop B: Rotor blade recycling: sustainable decommissioning practices for GFRP blades

Paul Leahy - Lecturer, University College Cork
Fergal Gough - PhD Student, University College Cork
When wind parks are decommissioned or repowered, bulky GFRP blades must be removed. Several options are available to deal with end-of-life GFRP including resale, repurposing, re-use, materials recovery, downcycling incineration or landfill. The workshop will explore the social, environmental and economic aspects of these options through group exercises.

11:30 am - 2:00 pm Workshop C: Materials and process evolution for XXL blades

Javier Callen - Project Manager, Nabrawind
Emilio Rodriguez Saiz - Materials Engineering Manager, Nabrawind
As size matters, XXL blades will suffer higher loads and will require materials with higher specific properties such as carbon fiber for not increasing excessively blade weight and overall WTG loads/costs. Additionally, higher fatigue loads will force to an evolution towards tougher resins and adhesives (epoxy). Materials & Process challenges will also arise due to the huge scale of the parts to be produced.
