6 FAQs about [Coating process of wind turbine blades]

Why do wind turbine blades have surface coatings?

However, composite materials perform poorly under transverse impact (rain droplets, hail, and solid particles) and also are sensitive to environmental factors. Wind turbine blade manufacturers employ surface coatings to protect the composite structure from exposure to these concerns.

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.

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.
