NREL validates thermoplastic resin for wind blades that is easier to recycle

By WPED Staff A new material for wind blades that can be recycled could transform the wind industry, rendering renewable energy more sustainable than ever before while lowering costs in the process.
The use of a thermoplastic resin has been validated at the National Renewable Energy Laboratory (NREL). Researchers demonstrated the feasibility of thermoplastic resin by manufacturing a 9-meter-long wind turbine blade using this novel resin, which was developed by Pennsylvania company Arkema. Researchers have now validated the structural integrity of a 13-meter-long thermoplastic composite blade, also manufactured at NREL.
In addition to the recyclability aspect, thermoplastic resin can enable longer, lighter-weight and lower-cost blades.
