叶片真空灌注工艺管路布置以及孔隙的形成

Piping Layout and Pores Formation in VARTM Manufacture Process of Wind Tube Blade

研究2种不同管路布置方法对风机叶片灌注时间以及灌注效果的影响,并对灌注过程中孔隙的形成进行了分析。实验表明,采用先开启叶片壳体主管道,再开启叶根铺层上方管路的方法,节约壳体灌注时间,同时也避免了叶根白斑的产生。

Study the influence of infusion time and infusion effect with two different piping layout in VARTM manufacture process of wind tube blade,as well as the formation of pores in VARTM manufacture process were analyzed.Experiments show that open the main pipelines of the blade shell and then open the pipelines on the blade root layers will save the infusion time but also to avoid the dry spot at the blade root.
