NREL Produces Wind Turbine Blade Components Using Arkema’s Thermoplastic Resin

At its Composites Manufacturing Education and Technology (CoMET) Facility, NREL is producing wind turbine blade components with Arkema’s Elium liquid thermoplastic resin.

Reduced Cost of Energy with Reduced Cycle Time

Unlike thermoset resins, which cannot be reheated, thermoplastic materials can potentially be recycled at the end of the wind turbine's life span.

These novel, thermoplastic resins may also reduce a wind turbine's levelized cost of energy by reducing cycle time, embodied energy, and capital costs. And because they can be thermally welded, thermoplastic resins may also eliminate the need for additional adhesive materials, expediting blade manufacturing and eliminating highly stressed bond lines.

Impact of Thermoplastic Resins on Wind Turbines

Ultimately, these thermoplastic resins have the potential to:

  • Reduce manufacturing costs by up to 30%
  • Decrease the critical cycle time during production by up to 20%
  • Improve durability in service and to enable easier blade repairs
  • Additionally, their recycling potential will help IACMI achieve its five-year goal of 80% recyclability for the composite structures of wind turbine blades

This research is part of the Institute for Advanced Composites Manufacturing Innovation's (IACMI's) 9-meter demonstration blade project. Positive results from the 9-meter blade experiment show promise for further research and potentially full-scale experimentation, and technoeconomic analyses further bolster these findings.
