A revolution in wind blade production
Enabling lighter blades with an exceptional balance of strength and toughness, Proxxima™ systems are a step-out resin for composite wind blade manufacture.
Ultra-low viscosity and controllable fast cure reduce manufacturing time, cutting component production costs often with little or no change to conventional processing equipment and methods. This resin system meets DNV certified performance and safety standards for use in wind rotor blades*. Proxxima resin systems provide a durable, efficient solution for the wind energy sector.
*Note: not all Proxxima solutions are DNV-certifiedProxxima systems’ benefits
Faster processing
Process high quality thick parts (like spar caps) and high-density components with ease.
- Ultra-low viscosity enables excellent fiber wet-out
- Proxxima resin system has demonstrated 5X faster infusion than incumbent epoxy systems
- Low peak exotherm produces higher quality laminates
Tougher
Reduce downtime while helping to extend operational lifespans by improving turbine blade crack and fatigue performance.
- Engineered to meet the rigorous demands of wind energy
- Enhanced fracture toughness ensures exceptional durability
- Certified by DNV for long-lasting, reliable performance*
Lighter
Proxxima resin systems are lighter than traditional thermosets.
- 5-10% less resin used enables production of lighter and longer blades that enhance energy capture.
- Demonstrated a 4% total weight savings in 31m blade manufacturing demonstration
Versatile composite solution
Proxxima resin systems can be used in the production of all wind blade composite components.
Processing flexibility
Proxxima resins enable efficiencies across composite manufacturing processes utilized for wind blade components:
- Vacuum-assisted resin transfer molding (VARTM)
- Pultrusion
A solution beyond wind blade performance
A panel-reviewed third-party study1 indicates that our Proxxima resin system has a reduced cradle-to-manufacturing output gate carbon footprint of product compared to many traditional thermoset resins. Contact us to learn more.
