Evaluation of urethane for feasibility of use in wind turbine blade design
A preliminary evaluation was conducted of the use of cast urethane as a possible material for low-cost blades for wind turbines. Specimen test data are presented for ultimate tensile strength, elastic modulus, flexural strain, creep, and fatigue properties of a number of urethane formulations. Data...

A preliminary evaluation was conducted of the use of cast urethane as a possible material for low-cost blades for wind turbines.

Based on these results, an analysis was conducted of a full-scale blade design of cast urethane that meets the design specifications of the rotor blades for the NASA/DOE experimental 100-kW MOD-0 wind turbine. Because of the low value of elastic modulus for urethane (around 457,000 psi), the design loads would have to be carried by metal reinforcement. Considerations for further evaluation are noted. |
