摘要: 风电叶片主梁帽通常采用单向经编织物,通过真空导入成型复合材料。由于真空导入工艺的特点以及织物参数的影响,都会对叶片设计带来一定的困难。选用国内外四种常用单行玻纤织物,研究了复合材料成型工艺和织物参数对复合材料厚度的影响。研究发现单向复合材料厚度与层数存在线性关系,而工艺参数对厚度影响不明显,织物参数对复合材料厚度有明显的影响。研究将为风电叶片设计提供一定支持,并为玻纤企业生产工艺参数调整提供了一定的借鉴意义。

Abstract: It is normal to use UD warp knitted fabric for the spar cap of the wind turbine blade through the vacuum infusion process. Due to the characteristics of vacuum infusion process and parameters of the fabric, it is hard to control the thickness of the composite panel. To investigate the variation of the thickness of the composite,and to analyze the influence of the parameters of the process and the fabrics on the thickness of the composites, 4 popular types of UD warp knitted fabrics were studied. With different vacuum infusion process, it is found that the parameters of the process don't have distinct effect on the thickness of the composite panel. However, the layers of the fabric affect the thickness a lot. And it has great difference among the parameters of different fabrics. Thus it is concluded that the parameters of the fabrics affect the thickness of the composite. This study provides data support to design the blade and give some useful suggestion to the production of the UD warp knitted fabrics.
