Design and Fabrication of Composite Blades for the Mod-1 Wind Turbine Generator.

Abstract

In the 1977 - 1978 time period, large U. S. wind turbine generators were being designed and built with metal or wood blades since the properties and manufacturing technology involved with these materials were well understood. However, the use of composites for construction of large blades was also being considered because of the significant potential advantages of this material, which include: Excellent fatigue properties and strength-to-weight ratio; Nearly unlimited design flexibility in accommodating optimized taper of planform and wall thickness, twist, and natural frequency control; High resistance to corrosion and other environmental effects, resulting in long service life; Low notch sensitivity with slow failure propagation rate; Low electromagnetic interference; Low-cost potential due to adaptability of the material to highly automated production methods.
