6 FAQs about [Coating and polishing of wind turbine blades]

How to protect wind turbine blades?

Fiber pulp reinforced coatings have a great potential for the blade protection. Nanocellulose reinforcement has potential to delay the degradation of coatings. Leading edge erosion of wind turbine blades is the most often observed damage mechanism of wind turbine blades, which causes also additional costs for the maintenance of wind turbines.

Can nanoengineered polymers provide anti-erosion coatings for wind turbine blade surface protection?

Possibilities of the development of new anti-erosion coatings for wind turbine blade surface protection on the basis of nanoengineered polymers are explored. Coatings with graphene and hybrid nanoreinforcements are tested for their anti-erosion performance, using the single point impact fatigue testing (SPIFT) methodology.

Why do wind turbine blades need a coating?

LEE is a major problem for large and extra-large wind turbines with tip speeds of over 80 m/s. To protect wind turbine blades from erosion, new highly protective coatings are required.

Can nanoparticle reinforcement be used for wind turbine blade surface protection?

In this paper, the potential of developing new anti-erosion coatings with nanoparticle reinforcement for wind turbine blade surface protection is demonstrated. The new types of coatings are based on polyurethanes reinforced with graphene or hybrid nanoscale particles.

What is surface layer protection for wind turbine rotor blades?

This chapter discusses surface layer protection for wind turbine rotor blades. The surface protection and coating can be a gelcoat or a paint and can be made of unsaturated polyester, epoxy, polyurethane or acrylic. As wind turbines are often erected in harsh climates, the blade surface will be exposed to conditions that cause erosion and wear.
