Wind turbine blades are gradually developing towards large scale lightening,in order to ensure the quality of wind power blade products,high modulus glass fiber fabric is introduced in the blade production process to enhance its performance.However because of the difficult perfusion of high modulus glass fiber fabric,VAP membrane is added to assist in the process design.Previously,imported VAP membranes have been used,under the huge cost pressure,the development of domestic VAP membrane is very urgent.The properties of domestic VAP membrane and imported VAP membrane were compared.The results show that compared with the imported VAP membrane,there are small differences in the air permeability and rubber penetration of the domestic VAP membrane,which could meet the requirements of the vacuum perfusion process of wind power blades.The development of the domestic VAP membrane is conducive to reducing the production cost of wind power blades and meets the demand for affordable development of wind turbine blades.
