Abstract

Pultruded composite materials have broad application prospects in the field of wind power generation. In this study, we explored the application of three different pultruded composites for the spar caps of wind turbine blades. Through comprehensive morphological, thermal, and mechanical analyses, as well as static and fatigue loading tests, we assessed the properties of these composites. Notably, the pultruded composites demonstrated high modulus, adequate strength, and excellent fatigue resistance. Among them, the optimal composite had an elastic modulus that was 46.4% higher than that of an E-glass vacuum-assisted resin-infused laminate. To further investigate their viability, we constructed a finite element model for a wind turbine blade with a pultruded composite spar cap using ANSYS. The results indicated that in a 94-m blade, replacing the E-glass vacuum-assisted resin-infused blade spar cap with the pultruded composite would result in a substantial 32.5% weight reduction. Finally, a 94-m blade was prototyped and tested, confirming its compliance with static and fatigue loading requirements. This study contributes to the advancement of composite materials and manufacturing methods for large-scale wind turbine blades.

拉挤加工纤维增强复合材料在大型风力涡轮机叶片中的性能和应用

拉挤复合材料在风力发电领域具有广阔的应用前景。在本研究中，我们探讨了三种不同的拉挤复合材料在风力涡轮机叶片撑杆帽上的应用。通过全面的形态、热和机械分析，以及静态和疲劳加载试验，我们评估了这些复合材料的性能。值得注意的是，拉挤复合材料具有较高的模量、足够的强度和出色的抗疲劳性。其中，最佳复合材料的弹性模量比 E 玻璃真空辅助树脂注入层压板高出 46.4%。为了进一步研究其可行性，我们使用 ANSYS 为带有拉挤复合材料撑杆帽的风力涡轮机叶片构建了有限元模型。结果表明，在 94 米长的叶片中，用拉挤复合材料取代 E 玻璃真空辅助树脂灌注叶片撑杆帽可大幅减重 32.5%。最后，对 94 米长的叶片进行了原型设计和测试，确认其符合静态和疲劳载荷要求。这项研究有助于推动大型风力涡轮机叶片复合材料和制造方法的发展。
