STUDY ON THE CHANGE OF THE UNIDIRECTIONAL COMPOSITE CURED PLY THICKNESS OF WIND TURBINE BLADES

Abstract

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.

Key words: thickness, unidirectional composite, unidirectional glass fiber fabric, wind turbine blade, vacuum infusion
