Aim: To evaluate the feasibility of using laser technology for cutting wind turbine blades made of composite materials, with a focus on recyclability and decommissioning.
Brief description: The project explores laser cutting as an alternative method for processing composite materials in wind turbine blades. Using CO2 and fiber lasers, the study assessed parameters like power, speed, and gas types to determine their effectiveness on different materials such as sandwich composites, polymer foam fillings, and glass fiber composites. The project aimed to identify optimal laser configurations for cutting large and complex structures while minimizing environmental impact.
Benefits: While not yet ideal for cutting large wind turbine blades, laser cutting shows potential for lower thickness materials and selective decommissioning. The findings highlight the need for advanced optics, effective fume extraction, and layer-by-layer approaches. This research supports innovation in sustainable recycling methods for the renewable energy sector, fostering more efficient and eco-friendly practices.
