摘　　要：“30.60”双碳目标的提出,风电行业迎来新的发展机遇。随着中国风电进入平价时代,风电机组通过不断增加单机容量来降低度电成本,由此也对风电叶片长度提出了不断增加的要求。风电叶片面临着“大型化、轻量化与低成本”的矛盾,新材料和新工艺是推动叶片走向风电平价时代的重要手段。本文评述了风电叶片行业的发展与趋势,指出影响叶片性能和成本的关键原材料,系统性地分析了增强纤维、夹芯材料、基体树脂和结构胶4种材料在叶片上的应用现状和发展趋势;探讨了高质量和绿色环保条件下叶片大型化对工艺发展的新要求,新工艺中的预浸料和拉挤技术是未来大叶片应用发展的主要趋势。最后,文章对新材料和新工艺在叶片上的创新应用提出了一些思考与建议,为平价时代风电叶片的大型化发展提供了重要参考。With the proposal of "30.60" Double Carbon Project, the wind power industry has ushered in new development opportunities. As China’s wind power enters the era of parity, the cost of power per kWh is reduced with the continuous increase of the single capacity of wind turbine system, which also leads to significant increase in the wind blade length. Wind blade is now facing the contradictive requirements of "large-scale, low-cost and lightweight". Both new material and innovative processing technology are of great importance to promote wind power to the parity era. On one hand, several key raw materials, including reinforcing fiber, matrix resin, core and structural adhesive, that affect the performance and cost of wind blade are systematically examined. On the other hand, high quality blades and green environmental protection are of great concern for the wind power industry, which indicates that new processing technology such as prepreg and pultrusion are playing more and more important role in future large scale blade manufacture. Thereafter, with systematic consideration of the materials and processing technologies in the development of wind blade, some suggestions are proposed on the introduction of these materials and technologies, in order to provide some reference for future large-scale wind blade development.
