New EU Hazard Classes 2023
• Endocrine disruption for human health
• Very persistent, very bioaccumulative
• Endocrine disruption for the environment
• Very persistent, very mobile
Avoid release to the environment!
Wind Turbine Blade Leading Edge Erosion
A different process takes place on the trailing edge leading to cracks running a significant part of the blade length.
Vibration/Cracks
Blade tip speed is in excess of 200 mph; larger turbines suffer worse vibration.
Blade Maintenance
What materials are used?
Most blades are made with fibreglass-reinforced polyester or epoxy. Carbon fibre or aramid (Kevlar) is also used as reinforcement material. Nowadays, the possible use of wood compounds, such as wood-epoxy or wood-fibre-epoxy, is being investigated.
