摘　　要：目前,风电叶片进入大型化阶段,叶片主梁采用玻纤拉挤板材设计可提高叶片的轻量化水平,提升行业竞争能力。本文采用拉挤环氧树脂、玻纤和脱模剂制作玻纤拉挤板材,分别研究不同玻纤纱线模量、玻纤含量、拉挤树脂和脱模剂对拉挤板材静态力学和疲劳性能的影响。实验结果表明:当板材采用H1玻纤纱线(90 GPa)或H2玻纤纱线(92 GPa),纤维含量控制在84.5±0.5%、脱模剂用量1.5%份得到的玻纤拉挤板材适用于风电叶片拉挤大梁轻量化设计和制造,具有广泛的应用前景。At present,the wind power blade has entered a large-scale stage,and the glass fiber pultruded sheet of the main beam of the blade can improve the lightweight level of the blade and improve competitiveness.In this paper,the glass fiber pultrusion sheet was made of pultrusion epoxy resin,glass fiber and release agent,and the influence of different yarn modulus,glass fiber content,pultrusion resin and release agent on the static mechanical and fatigue properties of the pultrusion sheet was studied.The test results show that the glass fiber pultruded sheet made of H1 glass fiber yarns(90 GPa)or H2 glass fiber yarns(92 GPa)with fiber content controlled at 84.5±0.5%and release agent dosage of 1.5%is suitable for lightweight design and manufacturing of wind turbine blade pultruded girder,and has a wide application prospect.
