A wind turbine blade includes several materials to improve stability, reduce weight, and add protection. The shell and spar cap, the blade’s support layer, consist of a fiberglass mesh bonded with resin. Older blades utilized a polyester resin, but most of the industry switched to epoxies as turbines got larger.
Composite materials are used typically in blades and nacelles of wind turbines. Generator, tower, etc. are manufactured from metals. Blades are the most important composite based part of a wind turbine, and the highest cost component of turbines.

6 FAQs about [How much material are wind turbine blades made of ]
What are wind turbine blades made of?
Most wind turbine blades materials are fiberglass, carbon fibre or aramid (Kevlar) heated together with resin to combine into a material that is light and yet still strong enough to withstand intense storms. Also being investigated is the possible use of wood compounds, such as wood-epoxy or wood-fibre-epoxy.
Why are wind turbine blades made of composite materials?
Composite materials are used for wind turbine blades because they are strong, lightweight, and durable, but their strength and durability present challenges for disposal. Between 80% and 90% of the blade mass is composite material, of which 60% to 70% is reinforcing fibers and the other 30% to 40% is resin (Jensen and Skelton, 2018).
What are wind turbines made of?
Learn more: Wind Energy According to a report from the National Renewable Energy Laboratory (Table 30), depending on make and model wind turbines are predominantly made of steel (66-79% of total turbine mass); fiberglass, resin or plastic (11-16%); iron or cast iron (5-17%); copper (1%); and aluminum (0-2%).
How many wind turbine blades are there?
Blade material The current U.S. fleet of wind turbines includes more than 190,000 blades that will have been in service for at least 20 years by 2040. Based on a 20-year lifetime, a total of 235,000 blades will be decommissioned by 2050.
What makes a wind turbine blade a good choice?
We invite you to read: “The Aerodynamics of Efficiency: Innovations in Wind Turbine Design” Fiberglass composites, a combination of glass fibers and a polymer matrix, have been instrumental in the evolution of wind turbine blades. They offer a remarkable balance of strength and flexibility, making them an ideal choice for blade construction.
How are wind blades made?
The most widely used technology to produce the wind blades, especially longer blades, is the resin infusion technology. In the resin infusion technology, fibers are placed in closed and sealed mold, and resin is injected into the mold cavity under pressure. After the resin fills all the volume between fibers, the component is cured with heat.
