摘要: 应用碳纤维制备风电叶片结构件是大型风电叶片制作技术的一个发展方向。为推动国产碳纤维的发展应用,给出了风电叶片对碳纤维预浸料的技术要求,研究了国产碳纤维预浸料和进口碳纤维预浸料的力学性能和工艺性能,通过对比分析发现,面密度低的国产碳纤维预浸料力学性能高于进口碳纤维预浸料,但面密度≥600g/m2的国内碳纤维预浸料的工艺性能较差,需要进一步改进。

Abstract: Application of carbon fiber for large structure of wind turbine blades is a developing direction of large-scale wind turbine blade manufacturing technology. To promote the development and application of domestic carbon fiber, this paper presents technical requirements of carbon fiber prepreg in wind turbine blade. Studies on mechanical properties and process performance of the domestic carbon fiber prepreg and imported carbon fiber prepreg were performed. The analysis results show that, mechanical properties of the domestic carbon fiber with lower surface density is higher than imported carbon fiber prepreg, but process performance of the surface density of 600 g/m2 for the domestic carbon fiber prepregs is poor, and need to be further improvement.

Key words: carbon fabric prepreg, process performance, mechanical properties, wind turbine blade
