摘　　要：以可再生的黄麻纤维作为加强材料,取代常用的玻璃纤维或碳纤维,与不饱和聚脂树脂复合制备小型垂直轴风力发电机叶片,并进行受力分析和理论计算。根据计算结果和材料的实际特性,确定了叶片的强度、尺寸。详细介绍了叶片的制造工艺,对叶片强度进行了实际测试。叶片中的麻纤维为可再生绿色天然材料,采用该材料制造叶片,不仅可以节约资源,也可以消除传统制造过程中产生的玻璃纤维粉尘污染,叶片报废后可以进行简单的填埋或焚烧处理。采用天然纤维代替玻璃纤维制造小型风力发电机叶片,具有一定的推广应用价值。A kind of small vertical axis wind turbine blade which applies natural jute fiber instead of glass fiber as a reinforcing material of unsaturated polyester is designed and manufactured. Theoretical analysis and calculation of the blade force is conducted. According to the calculating results and actual properties of the materials, suitable size of the blade is determined, the strength of blade is tested. In this paper the detail manufacturing process is introduced. The natural jute fiber in the blade is a green material that is recyclable and renewable. By the material substitution, this method not only saves resources ,reduces waste, but also avoids pollution in the manufacturing process. Used blades can be disposed by simply land-fill or incineration.
