Problems solved by technology

At present, the materials used for wind turbine blades have been developed from wood, canvas, etc. to metal (aluminum alloy), glass fiber reinforced composite materials (glass fiber reinforced plastics), etc. When these materials are used for wind turbine blades, they are usually manufactured by hand lay-up process. The resulting wind turbine blades are heavy, not resistant to fatigue, and are also prone to lightning strikes, and the forming speed of the blades is also slow, and it is difficult to ensure uniform quality between the blades

Abstract

The invention relates to a wind power generator blade material which mainly comprises the following raw materials: 68-70 parts by weight of nylon 6 and 29-31 parts by weight of carbon fiber. The carbon fiber is about 30 percent smaller than a glass fiber in density and 40 percent larger than the glass fiber in strength, particularly the carbon fiber is 3 to 8 times higher than the glass fiber in modulus; and a prepared blade is more than double of the rigidity of a glass fiber composite material blade.

Description

technical field [0001] The invention relates to a wind power generator blade material, which belongs to the technical field of wind power generation equipment. Background technique [0002] As the world's energy crisis becomes more and more serious, and the public's demand for improving the ecological environment is increasing, wind energy, as a clean and renewable energy source, is increasingly valued by governments. At present, about 50 countries around the world have promulgated relevant laws and regulations to support the development of renewable energy, which have played a vital role in the development of wind power. The wind power industry is gradually developing into a new industry that has begun to take shape. [0003] At present, various countries are speeding up the pace of research on wind turbines, and constantly introducing new technical equipment. A wind turbine is a power generation device composed of blades, transmission systems, generators, energy storage e...
