With the continuous improvement of wind power, capture the wind blade is bigger, more and more is also high to the requirement of wind turbine blades, the blade of the lighter materials, the higher the strength and stiffness, the stronger the blade to resist the ability of the load, the leaf length increased at the same time, how to reduce the weight of the wind turbine blade became the wind power equipment industry needs to confront problems.
Therefore, lightweight, high strength, good corrosion resistance, and designable composite materials are the preferred materials for wind turbine blades. The same is true for the blades of 300 w wind turbines. The glass fiber materials are made from the waste glass, which is made of fiber cloth or fabric through high temperature flux, wire drawing, yarn winding, weaving and other processes.
Glass fiber bundle is composed of hundreds or even thousands of root monofilament, can be used for electrical insulation, anti-corrosion, moisture-proof, heat insulation, sound insulation, shock absorption, etc., is one of the typical wind turbine blades, radar cover and so on. Glass fiber materials from thermoplastic resin or thermosetting resin and glass fiber, have many advantages.
It has high tensile strength and high elastic modulus. Good rigidity and dimension stability of composite parts; At the same time it has noncombustible, resistance to chemical corrosion, water imbibition is small, good heat resistance, not easy combustion, good workability, can be made into shares, beam, blanket, weaving, good transparency, through light, cheap, can be recycled, etc.
As the wind blade material for 300 w wind turbines, it can not only improve the utilization rate of wind energy, but also expand the capacity of the single wind turbine. Because carbon fiber has higher specific strength and stiffness than glass fiber, carbon fiber composite materials are widely used in wind turbines, including 300 w wind turbines. http://www.titanwindturbine.com/
