A new carbon fiber material could bring cost and performance benefits to the wind industry if developed commercially, says a study led by Sandia researchers. Wind blades containing carbon fiber weigh 25% less than ones made from traditional fiberglass materials. That means carbon fiber blades could be longer than fiberglass ones and, therefore ...

Turbine blades are difficult to recycle into highvalue goods because they are made of fiberglass and composite materials. As a result, recycling often involves downcycling the material into lowvalue building products. This approach isn't usually economically viable though; it often has a higher cost than just disposing of the blades.

Wind turbine blades in the existing US fleet average around 50 meters in length, or about 164 feet (approximately the width of a football field). And with recent trends to use longer blades on bigger turbines and taller towers to increase electricity production, a few of the largest blades produced today reach 6080 meters in length.

Blades make up approximately 20% of the total cost of the turbine. The cost varies based on the materials used. Blades are manufactured either with glass fiber or a hybrid of glass and carbon fiber. While glass fiber blades have lower material costs, hybrid blades require less labor. The price difference between the two ends up being negligible.

It ran for hours and continued generating electricity. However, the blades suddenly failed operating after continuously operating for 1100 hours (Fig. ) (Carlin et al. 2003). Hence, appropriate selection of materials as a blade material for wind turbine has proven to be of utmost significance in the early history of wind turbine development.

Raw Materials. A wind turbine consists of three basic parts: the tower, the nacelle, and the rotor blades. The tower is either a steel lattice tower similar to electrical towers or a steel tubular tower with an inside ladder to the nacelle. The first step in constructing a wind turbine is erecting the tower.

Turbine blades can reach speeds of up to 180mph at their tip and are subject to immense aerodynamic, inertial, and gyroscopic loads. They must therefore be made from stiff and lightweight materials resistant to highcycle fatigue. By exhibiting such properties, glass fiberreinforced polymer (GFRP) has become the most common material for blade ...
