摘要
大功率风电机组尤其是海上风电大尺寸复合材料叶片对于材料的强度、耐疲劳性能及长期使用可靠性提出了更高的要求,高强度高刚度碳纤维增强复合材料拉挤板材为大尺寸风电叶片主梁结构提供了最佳解决方案.国产低成本大丝束碳纤维生产技术突破为碳纤维增强复合材料风电板材规模化应用奠定了基础,碳纤维/玻璃纤维(碳玻)混杂成型技术、碳纤维/聚氨酯体系拉挤成型技术为风电板材提供了更多可供选择的技术途径.本文结合上海石化 48K大丝束碳纤维在风电领域应用研究成果及国内外风电板材新型技术进展,总结了大丝束碳纤维复合材料在风电叶片板材的应用途径.
Abstract
High power wind turbines,especially large-sized composite blades for offshore wind turbines,have higher requirements for material strength,fatigue resistance,and long-term reliability.Carbon fiber reinforced composite material extruded plates are the best solution for the main beam structure of large-sized wind turbines.The breakthrough in domestic low-cost large bundle carbon fiber production technology has laid the foundation for the large-scale application of carbon fiber reinforced composite materials in wind power panels.Carbon glass hybrid molding technology and carbon fiber/polyurethane system pultrusion molding technology provide more technical op-tions for wind power panels.Based on the research results of Shanghai Petrochemical's 48K large bundle carbon fi-ber application in the wind power field and the progress of new technologies for wind power panels at home and a-broad,the application pathways of large bundle carbon fiber in wind power panels are summarized.
