大风机叶片材料轻量化的探索

Exploration on Material Lightweighting for large Wind Turbine Blades

分析了梁帽的轻量化发展方向,研究了梁帽的不同材料、不同工艺的性能,通过实验及数据统计的分析,对比结果表明:同为玻纤或碳纤维,采用拉挤成型工艺的拉挤板性能要优于灌注工艺成型的织物灌注玻璃钢性能。碳纤维拉挤板性能最优,是轻量化的首选。

The developing direction of lightweight spar caps was analyzed,and the performances resulting from different materials and different processes of spar caps were studied.The analysis and comparison of experiments and data statistics have showed that the performance of glass or carbon fiber pultruded panels is better than that of GRP products molded by resin infusion process with fabrics as reinforcement.Carbon fiber pultruded panels have the best performance so that they can be the priority for lightweighting.
