The Application of Multiaxial Fabric Blower Blade and its Strength Theory Check

Abstract:

The scale application of wind energy conforms to the demand of sustainable development in our country. However, with the blower’s blade lengthened, the weight will also increase. If it is made in traditional way, it would reach tons of orders of magnitude, and the centrifugal force on the blade root will become very large because of the tip speed ratio. When the wind is large enough, the blade force model is equivalent to a cantilever beam structure, thus the material of extended wind turbine blade should possess high strength and high modulus and should be light. Otherwise the blade’s life will be shortened [1]. In many of the materials, the multi-axial fabric is a good carrier to meet these requirements. If the blade in the extended length also can meet the strength requirements, the multi-axial fabric will be the top choice for future wind-driven generator blade design and manufacture.
