摘要整理
湿法铺层和真空辅助树脂传递模塑（VARTM）是E-玻纤/环氧树脂层板复合材料最常用的成本效益型制造工艺，在风力机叶片制造领域应用广泛。本研究对比了两种工艺制备的玻纤增强复合材料（GFRP）层板的疲劳性能。在应力水平为极限拉伸强度0.4倍的条件下，真空辅助树脂传递模塑试样的疲劳寿命比湿法铺层试样延长85%。真空辅助树脂传递模塑试样的平均极限拉伸强度提高50%，纤维-基体界面结合增强导致疲劳抗力显著提升。扫描电子显微镜断口分析表明，真空辅助树脂传递模塑疲劳试样的纤维/基体界面结合质量更优，这是其疲劳性能提升的主要原因。在低应力水平下，真空辅助树脂传递模塑复合材料可承受4.5倍更多的加载循环次数，表现出优异的疲劳性能。研究结果为风力机叶片材料选择和工艺优化提供了重要参考依据，对风电装备的可靠性设计具有指导意义。
