Wind

Trusted by leading turbine manufacturers and maintenance teams worldwide for bonding strength, industry-leading fatigue and impact resistance, minimal surface preparation, lightweight durability, and flexibility for a wide range of structural and assembly applications.

Wind turbines on a green hilltop

SCIGRIP has a long history of working in the wind energy market including onshore and offshore wind turbine manufacturing, field repair and retrofit applications.

In modern wind turbine manufacturing, performance starts at the bond line. Mechanical fixings add weight and complexity, and welding is often unsuitable for the composite structures and mixed material assemblies that modern turbine design demands. SCIGRIP structural adhesives provide a seamless, reliable and aerodynamically clean alternative.

They utilise dissimilar material bonding, multiple working times, minimal surface preparation, impact resistant gap filling and provide reduced bondline readthrough, environmental resistance and a clean and finished look.

Illustration of three wind turbines

Yaw Mechanism

Designed with composite materials for strength, light weight and durability to rotate the turbine towards the wind.

Requires fast strong bonding of dissimilar materials with weather-proof sealing and corrosion resistance.

Rotor Blades

Constructed from composites for high strength and rigidity with minimal weight; built to ensure impact, vibration and harsh environmental conditions.

Requires fast, no sag, strong bonding of dissimilar materials, while subject to variable weather conditions and constant vibration.

Rotor Hub

Composite shell enclosing cast-iron heavy-duty, componentry connecting the nacelle to the rotor
blades. Requires strength to support heavy blades and vibration resistance from continuous motion.

Requires strong, fast bonding and sealing of dissimilar materials while withstanding variable weather conditions and constant movement.

Tower

Built from steel or concrete to support the nacelle and blade weight, needs to withstand harsh
environments and remain stable during continuous turbine motion.

Requires fast, no sag, strong bonding and sealing in harsh environmental conditions, subject to constant impact and vibration.

Field Repairs

Repairs of trailing edge splits, lightning strike damage or shipping damage.

No boiling at large bonding gaps up 150mm, No surface preparation required, fast injection and rapid curing so is well suited for repair or backfill.

Bond using:

Nacelle

The housing on the top of the tower containing the key turbine componentry made of composites for strength, durability and aerodynamic design to sustain extreme weather conditions.

Strong, fast bonding of dissimilar materials, while providing impact and vibration resistance without altering the profile or function of the mechanism.

Vortex Generators

Thermoplastic devices designed to improve aerodynamic performance by manipulating airflow patterns.

Requires fast, no sag, strong bonding in harsh environmental conditions, subject to constant impact and vibration.

Drill and Fill Repairs

Drill-and-fill to fix internal defects in composite materials.

Repair internal debonding, delamination and adhesive voids with SG350L. It does not boil at large bonding gaps up to 150mm.
