摘要/Abstract

摘要： 风电叶片用单向复合材料的单层厚度是非常重要的设计参数,不准确的设计取值将使得风电叶片的主梁帽和腹板粘接厚度超差,叶片结构寿命大幅度降低。本文系统地研究了两种典型的风电叶片用单向复合材料的厚度变化规律,发现单层厚度主要受原材料种类、铺层数的影响,而一些典型的工艺参数如真空度、温度等则影响很小。研究还发现总厚度与层数存在线性关系,可以用数学模型描述。此项研究为合理使用原材料进行叶片设计打下了良好的基础。

Abstract: The cured ply thickness (CPT) of unidirectional composites is a very important parameter for the design of wind turbine blades. If the value of CPT is not accurate, the adhesive thickness of web and spar cap may be in excess of the deviation requirements, then the service life of the blade structure would be greatly reduced. The paper studied the change law of the CPT of two kinds of unidirectional composites. It was found that the CPT is mainly affected by the kind of raw materials, number of layers. And, some typical parameters such as degree of vacuum, temperature has little effect. The study also found that there was a linear relationship between the total thickness and number of layers. It can be described by mathematical model. This study laid a good foundation for the rational design of the blade.

Key words: cured ply thickness, unidirectional composite, wind turbine blade, vacuum infusion
