RELIABLE SUPPLY

  • Proven Performance

    • 63 GPa laminate 0° tensile modulus (at 70% FVF — Fiber Volume Fraction) – true performance to enable longer, lighter blades.




    • Balances increased FVF to maintain strong fatigue performance.

  • Consistency and Productivity

    • Pultrusion delivers consistent glass content for reliable performance and eliminates on-site spar cap infusion for improved productivity.




    • Low porosity enables mechanical stability and quality consistency.




    • Double-sided PA66 peel ply cover with easy peel-off, enabling an ideal contact surface for excellent bonding properties.

  • Reliable Supply

    • Owens Corning® H2 Glass is continuously produced at scale and increasing capacity, delivering reliable product supply and consistency.

Applications

Ultraspar™ 2 is a high-performance pultruded profile custom-designed for wind blade spar caps. Ultraspar™ 2 enables blade designers to optimize the weight and maximize the length and strength of wind blades.
