摘要
针对风电叶片市场需求和聚氨酯树脂性能优势,开发出聚氨酯体系大型风机叶片专用玻璃纤维产品,综合对比了浸胶纱线、单向纱线增强层合板和织物增强层合板性能。研究结果表明:该产品与聚氨酯树脂体系具有良好的相容匹配性和界面结合强度;纱线模量可达到96.20GPa,织物拉伸强度可达到54.47GPa;织物吸胶量较低,复合材料中纤维体积分数可达到60%,高玻纤含量条件下具有优异的静态机械性能和疲劳性能,是大型风机叶片设计开发和高效率制造的重要材料选择。
According to the market requirements for wind turbine blades and the advantages of polyurethane resin,a special glass fiber dedicated for large wind turbine blades based on polyurethane system was developed.The properties of impregnated rovings,unidirectional roving reinforced laminates and fabric reinforced laminates were compared.The results have showed that this glass fiber has good compatibility and interface bond strength with polyurethane resin system.The modulus of roving is up to 96.20 GPa,and the tensile strength of fabric is up to 54.47 GPa.The resin pick up of fabric is low,so that the fiber volume fraction in the composite is up to 60%,and the composite has excellent static mechanical properties and fatigue properties under this condition.It is an important material choice for the design of large wind turbine blades and the high efficiency manufacturing.
