摘要: 系统分析了以降低风电叶片成本为目标开发的真空导入型聚氨酯树脂,分别进行了粘度特性、工艺窗口、固化特性和力学性能的分析。分析表明该树脂体系与常用环氧树脂体系相比具有初始粘度低、进胶速率大、韧性高和粘接性能好等优点,表现为灌注时间的缩短、层合板抗压缩性能和横向性能的提高。将这一树脂体系应用于风电叶片主承力结构的制造,通过提高纤维体积含量,可进一步降低叶片的生产成本。

Abstract: In this paper, the vacuum infusing polyurethane resin, which aims at reducing the cost of the wind turbine blade, was studied. The results show that the resin system has the advantages of low initial viscosity, high feed rate, high toughness and good adhesion properties compared with the commonly used epoxy resin system. The application of this resin system to the main bearing structure of the wind turbine blade is made, and the production cost of the blade can be further reduced by increasing the fiber volume content.

Key words: polyurethane, vacuum infusion, wind turbine blade
