摘要
随着海上风电行业的高速发展,海上风电机组单机发电容量已达18 MW以上,叶片长度已达120 m以上。为降低叶片质量和提高叶片强度,碳纤维复合材料已经逐步应用于大功率海上风电叶片。目前主要采用树脂传递模压工艺加真空辅助灌注(Vacuum Assisted Resin Transfer Moulding,VARTM)技术来制作风电叶片用碳纤维主梁,但容易产生异物、分层和孔隙等缺陷。采用制作模拟缺陷样块的方法来制作碳纤维缺陷样块,研究相控阵检测方法,并在风电叶片碳纤维主梁验证检测效果,对于碳纤维复合材料在风电叶片行业的应用具有重要意义。
With the high-speed development of offshore wind power,the single unit power generation capacity of offshore wind turbines has reached over 18 MW,and the blade length has reached over 120 meters.In order to reduce blade mass and improve blade strength,carbon fiber composite materials have gradually been used for high-power offshore wind turbine blades.At present,vacuum assisted resin transfer molding(VARTM)technology is mainly used to produce carbon fiber main girder of wind turbine blades,but it is prone to defects such as foreign objects,delamination,and porosity.The method of making simulated defect samples is adopted to make carbon fiber defect samples,and the phased array detection method is studied.The detection effect is verified on the carbon fiber main girder of wind turbine blades,which is of great significance to the application of carbon fiber composites in the wind turbine blade industry.
