The material of the wind turbine blades, what materials are currently made of the wind turbine blade

Dear, I'm glad that the most common use of this problem is currently glass fiber reinforced polyester (epoxy) resin. However, with the development of high-power generator sets, the blade length continues to increase, and in order to prevent the blade tip from hitting the tower under extreme wind loads, the blades are required to have higher stiffness. Foreign experts believe that the performance of glass fiber composite materials has tended to the limit and cannot meet the requirements of large blades, so the effective way is to use carbon fiber composite materials with better performance.

Hello dear, wind turbine blades are an important part of wind turbines and are usually made of composite materials. The following are the main materials of common wind turbine blades: glass fiber reinforced plastic (GFRP) for short:

Glass fiber reinforced plastic is one of the most commonly used materials for wind turbine blades. It consists of fiberglass and a thermosetting resin (usually epoxy). Fiberglass provides strength and stiffness, and resins provide corrosion resistance and protect the function of fiberglass.

Carbon Fiber Reinforced Plastic (CFRP): Carbon fiber reinforced plastic is a high-performance composite material. It consists of carbon fiber and thermosetting resins such as epoxy resins.

The higher strength and stiffness of carbon fiber makes the blades of carbon fiber reinforced plastic lighter, stronger and more efficient. Polyester resin: Polyester resin is a commonly used thermosetting resin that is widely used in the manufacture of wind turbine blades.

It has good corrosion resistance and weather resistance, and can be well combined with glass fibers to form a strong material. The above materials usually undergo special processes and manufacturing processes, such as spinning, molding, and curing, to form a strong, stiff, and lightweight blade structure. The selection and use of specific materials depends on factors such as the design requirements, size, performance needs, and manufacturing cost of the blade.

The harm to people caused by the manufacture of wind turbine blades is the effect of radiation.

The manufacture of wind turbine blades has a certain radiation impact on the human body, and protective measures need to be taken.

Materials for the manufacture of wind turbine blades:

Blades are an industry with high certainty, large market capacity and clear profit model in wind power components. With the easing of the tight supply and demand situation, the wind power blade industry will also undergo a transformation from a group of heroes to several powers, and China's wind power blade industry is experiencing an industry reshuffle and integration.

With the expansion of the scale of the wind turbine blade market, the cost and selling price will fall, but the cost of enterprises with scale, technology and cost advantages will decline faster than the selling price, and the profit will exceed the average. The future industry competition pattern requires manufacturers to expand their scale, reduce costs, and maintain certain advantages in technology.

There are many materials for wind turbine blades: glass fiber, resin, balsa wood and other fillers are used to improve some of the properties of the product.

Due to the different performance requirements of the application, and the epoxy group of the latter is attached to the phenyl nucleus or aliphatic hydrocarbon with epoxypropyl ether, which is selected from the operational requirements. No need to withstand high temperatures. For reliable bonding, frames: dibutyl phthalate or dioctyl phthalate. <>

The materials used to process blades are wood, metal, engineering plastics, glass fiber reinforced plastic, etc.

Modern micro and small wind turbines also use wooden blades, but wooden blades are not easy to make twisted shapes. Large and medium-sized wind turbines rarely use wooden blades, and those that use wooden blades are also made of solid wood with good strength as blade longitudinal beams to bear the force and bending moment that the blades must bear when working.

In modern times, the blade is made of steel pipe or D-shaped steel as a longitudinal beam, steel plate as a rib beam, and filled with foam plastic and covered with FRP skin, which is generally used in large-scale wind turbines.

The steel pipe of the blade longitudinal beam and the cross-section of the D-shaped steel from the blade root to the blade tip should be gradually reduced to meet the requirements of twisting the blade and reduce the weight of the blade, that is, to make a beam of equal strength.

Wind power is one of the most popular renewable energy sources at present, and wind power blades are one of the most important components. There are many different types of materials for wind turbine blades, but the most common ones are mainly fiberglass and carbon fiber composites.

FRP is an excellent composite withering material, with high strength, stiffness and durability, and relatively low at the same time, so it is widely used in the manufacture of wind power blades. Another common material is carbon fiber composite, which has higher strength and stiffness than FRP before rotting, which can effectively reduce the weight and wind resistance of wind power generation blades, thereby improving power generation efficiency.

In addition, there are some other materials, such as aluminum, wood, etc., which are also widely used in the manufacture of wind blades in certain application scenarios. Regardless of the material used, material selection and design are critical to the sustainable development of wind power.
