Feasibility of Application of Epoxy Resin in the Wind Turbine Blade Industry

Wind energy, as a clean and renewable energy source, is increasingly receiving attention from countries around the world. Chinoiserie's wind power industry has developed rapidly and has become one of the world's major wind power markets after Europe, the United States and India. From 2003 to 2008, Chinoiserie's installed capacity grew rapidly: the cumulative installed capacity increased from 567000 kilowatts at the end of 2003 to 13242200 kilowatts at the end of 2008, an increase of 22.3 times, and the new installed capacity in 2010 is likely to exceed 16 million kilowatts. China is facing huge opportunities for wind power development, and the market demand for wind power equipment is constantly increasing. In addition to the increasing demand for wind power equipment, the supply capacity of wind power equipment components such as blades still cannot fully meet the demand, and the market demand potential is enormous.
However, at such a base level, it is difficult to reproduce the growth that doubled in previous years in 2011. It is estimated that Chinoiserie will maintain an annual growth rate of about 15 million kilowatts for a long time in the future. The decrease in installed capacity growth rate will inevitably lead to intensified competition and structural adjustment, and both downstream developers and upstream equipment manufacturing enterprises are facing growth challenges. The only solution is to achieve a shift in growth mode: from focusing on quantity and speed to focusing on quality and efficiency, and for upstream equipment manufacturers, technological innovation and exploration are particularly important.
For composite materials currently used in the wind power industry, materials and processes are the two most important factors. This article discusses the application of epoxy resin in the wind power industry.
Epoxy ester resin (also known as "Vinyl ester resin resin") is a new thermosetting resin that appeared in the 1960s after phenolic resin, unsaturated polyester resin and epoxy resin. Epoxy alkenyl ester resin was prepared from epoxy resin and methacrylic acid through Cycloaddition reaction. It retains the basic chain segments of epoxy resin and has excellent processing properties of unsaturated polyester resin. After curing under appropriate conditions, it exhibits certain special and excellent properties, also known as unsaturated epoxy resin. It can be inferred from the molecular structure of epoxy resin that it has the advantages of both unsaturated polyester resin and epoxy resin.
Since its inception, epoxy resin has gradually entered the application field of epoxy resin. Epoxy resin was initially a corrosion-resistant resin, but by the end of the last century, it had become the preferred resin in the field of anti-corrosion. With the improvement of the performance and awareness of ethylene oxide ester resin, it has gradually been applied to various composite industries, including special industries such as yachts and sports helmets. Naturally, with the development of the wind power industry, epoxy resin has also been applied or promoted in the wind power industry.
