Carbon Fiber and Wind
Carbon Fiber and Wind

 

Panex 35 has created the standard in wind turbine reinforcement:

  • A more slender blade profile
  • A lighter, longer, stiffer, and stronger wind turbine blade
  • An overall more efficient wind turbine
  • Reliable carbon fiber at a sustainable price

Zoltek’s uni-directional fabrics and prepreg tapes are pushing the wind energy industry to higher levels of performance. Longer and lighter blades mean more energy output per revolution.

Wind Energy Carbon Fiber vs Glass Fiber

Zoltek’s advanced processes and tools allow simple, high-speed lay-down of carbon fiber tow, prepreg, and fabrics.  Our proprietary material dispensing tools (used for prepreg or fabrics) have accelerated the application process saving our customers time and money.  Additionally, Zoltek provides comprehensive technical support for spar cap manufacturing.

Without a single blade failure since it was adopted in 2004, Panex 35 has become the dominant carbon fiber in wind energy.

 

Zoltek's Wind Energy Products

 

Prepreg

Wind Energy PrepregZoltek’s heavy areal weight carbon fiber prepregs are ideal for rapidly building up part thickness with excellent composite properties, and allows for higher manufacturing throughput at a lower cost. A wide selection of epoxy resin formulations meets a variety of processing and composite property requirements for tack, toughness, flow in cure, surface finish, cure time, cure temperature, and delivered composite strength and modulus.
