Because fiberglass composite materials have a light specific gravity, good fatigue strength and mechanical properties, can carry harsh environmental conditions and random loads, and are significantly lower cost than carbon fiber and other composite materials, they are the most commonly used in blade manufacturing. Blades account for the largest cost among components of wind turbines.

At the same time, the increase in the length of wind turbine blades has gradually enabled wind power installations to move into deep sea areas, which has put forward higher requirements for the corrosion resistance of wind turbine blades, tower bases, etc. The resin coating covering the fiberglass structure on the blade skin can effectively increase the corrosion resistance. Corrosion intensity.

In addition, glass fiber with cost advantages can reduce costs and increase efficiency, and its penetration rate in the photovoltaic frame industry is expected to gradually increase in the future. Therefore, the rapid growth of wind power and photovoltaic installed capacity will drive the demand for fiberglass.
