6 FAQs about [High-altitude anti-corrosion of wind turbine blades]

How to protect wind turbine blades from erosion?

To protect wind turbine blades from erosion, new highly protective coatings are required. A promising area in the development of protective coatings is the creation of internal structures within the coating material, which can reflect or scatter the stress waves arising from raindrop impact.

What causes the erosion of wind turbine coatings?

The erosion of coatings is caused by multiple random impacts (by rain droplet, hail, or other particles), which cause deformation and stress wave propagation in the coatings, which in turn leads to damage [ 2, 5 ]. To prevent or delay the erosion of wind turbine blades, the development of highly erosion resistant coatings is desirable.

Can particle engineered anti-erosion coatings protect wind turbine blades?

On the potential of particle engineered anti-erosion coatings for leading edge protection of wind turbine blades: Computational studies. In IOP Conference Series: Materials Science and Engineering, Proceedings of the 41st Risø Symposium, Roskiled, Denmark, 7–10 September 2020; IOP Publishing: Bristol, UK, 2020; Volume 942, p. 012027.

Can anti-erosion coatings reduce wind turbine waste?

Photographs showing tons of non-recyclable composite blades, placed in landfills, appeared on pages of newspapers. The goal of development of anti-erosion coatings, which should increase the lifetime of wind turbines, can reduce the amount of composite wastes, at least for the time, until a new solution is available.

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 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.
