6 FAQs about [Spray on wind turbine blades]

What coating is used for a wind turbine blade?

However, the outer surface of the blade is usually a layer of epoxy resin. Thus, the epoxy resin was chosen as the substrate coating for the aluminum substrate, in order to simulate the outermost layer of a wind turbine blade.

How to protect wind turbine rotor blades?

Fundamentals of surface protection for wind turbine blades Wind turbine rotor blades are protected on the surface by gelcoat or paint. The surface protection is necessary because there will always be pinholes in the composite – the laminate – of which the rotor blades are made.

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.

Can elastomeric coatings protect wind turbine blades?

The development of two novel elastomeric erosion resistant coatings for the protection of wind turbine blades is presented. The coatings are prepared by modifying polyurethane (PU) with (i) hydroxyl functionalised graphene nanoparticles (f-GNP) and (ii) f-GNP and a hydrophobic silica-based sol–gel (SG).

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.

What is the substrate coating for a wind turbine blade?

Thus, the epoxy resin was chosen as the substrate coating for the aluminum substrate, in order to simulate the outermost layer of a wind turbine blade. The System 2000 epoxy resin, manufactured by Fibre Glast Developments Corporation, was used as the substrate coating layer in this study.
