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, capture more energy in locations with low wind.
Carbon fiber has known benefits for reducing wind turbine blade mass due to the significantly improved stiffness, strength, and fatigue resistance per unit mass compared to fiberglass; however, the high relative cost has prohibited broad adoption within the wind industry.At the center (or beginning or start) of all structural composites is PX35 Carbon Fiber Tow.
Global carbon fiber wind turbines blades market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
GE launches onshore wind turbine with two-piece carbon fiber blades.CompositesWorld
Park Aerospace Corp.
GE Renewable Energy launched its new Cypress onshore turbine platform, and the next model from that platform, GE’s 5.3-158 turbine. The platform advances the proven technology of GE’s 2 MW and 3 MW fleets, which serves an installed base of nearly 20 GW, while also utilizing architecture and innovations from the 4.8-158 turbine introduced in 2017.
The Cypress platform, which also includes the 4.8-158, will be powered by a revolutionary two-piece carbon blade design, enabling blades to be manufactured at even longer lengths and improving logistics to offer more siting options.
Longer blades improve annual energy production (AEP) and help drive down Levelized Cost of Electricity (LCOE), and the proprietary design of the new blades will allow these larger turbines to be installed in locations that were previously inaccessible. According to GE Renewable Energy, the new design enables blade assembly onsite, reducing the costs for permitting equipment and road work required for transporting longer blades.
ZOLTEK’s PX35 tow has an excellent balance of strength and stiffness for demanding wind energy applications. The large tow size (50K) enables high throughput processing.
