Vacuum perfusion method for outer wrapping edge of wind turbine blade

Abstract

The invention discloses a vacuum perfusion method for the outer wrapping edge of a wind turbine blade. The vacuum perfusion method is used for wrapping and connecting of the peripheral edges of a pressure surface and a force suction surface. The vacuum perfusion method for the outer wrapping edge comprises the steps that 1, the outer surface of a first area of the pressure surface and the outer surface of a second area, opposite to the first area, of the force suction surface are paved with reinforcing material layers in a fixed mode; 2, the outer surfaces of the reinforcing material layers are paved with release cloth and flow guiding nets in sequence; 3, the outer surfaces of the flow guiding nets are paved with sealing membranes used for sealing the outer wrapping edge of the wind turbine blade; and 4, vacuum perfusion is conducted on the interiors of the sealing membranes by using a vacuum device. According to the vacuum perfusion method for the outer wrapping edge of the wind turbine blade, the gel content of fiber cloth and bubbles in cloth layers are reduced, the fiber content is improved, mechanical properties of a product are improved, the product performance stability isstrengthened, and the product quality is improved.

Description

technical field [0001] The invention relates to a vacuum pouring method for an outer wrapping edge of a wind power blade. Background technique [0002] With the depletion of conventional petroleum energy, wind energy, as a clean renewable energy, has been recognized by countries all over the world for its development potential. As one of the most critical and core components of wind power generation equipment - wind turbine blades, its design and material selection determine the performance and power of wind power generation equipment, and are important factors to ensure the normal and stable operation of the unit. Therefore, to improve the comprehensive performance of wind turbine blades and reduce power generation costs, higher requirements are put forward for the design, material selection and molding process of wind turbine blades. [0003] At present, according to the summary of existing technologies, the main forming process of the outer edge of wind power blades is h...
