摘要： 在风电叶片真空灌注制备过程中,透气隔离（VAP）膜因具有单向透气性,可以持续抽掉真空袋膜内的气体,而并不抽出树脂,解决叶片成型灌注中因局部存有气泡而引起的未灌透问题。对不同型号VAP膜的透气度进行测试,并利用光学显微镜对该膜的微观结构进行观察,结果表明,VAP膜透气度与灌注成型的环境压差有关,且与其微观孔洞数量有关。

Abstract: In the vacuum infusion process of preparing wind turbine blades,the unidirectional permeability of Vacuum Assisted Process （VAP） membrane can continuously pump out the air inside the vacuum bag membrane,prevent the resin from being pumped out,and solve the process problem of not being infused through due to the existence of air bubbles locally in the blade molding and infusion. The air permeability performance of different models of VAP membrane was tested,and the microstructure of VAP membrane was observed by optical microscope. The test results show that the air permeability of VAP membrane is related to the ambient pressure difference in molding and infusion and the number of its holes.

Key words: wind turbine blades, VAP membrane, air permeability
