The invention provides a method for manufacturing a composite material blade. The method comprises the following steps as follows: manufacturing a blade preformed part by using a preforming die, moving the blade preformed part to a die, placing an air bag, closing the die, heating and pressurizing the die, carrying out demoulding and surface treatment and the like. The blade obtained with the manufacturing method has the advantages of being light in weight, simple in structure, high in strength and high in integrity. 本发明提出的一种复合材料叶片的制作方法，包括利用预成型模制作叶片预成型件、将所述叶片预成型件移动到模具上、放置气袋、合模、对模具加热加压、脱模、表面处理等，通过该制作方法获得的叶片具有重量轻、结构简单、强度高、一体性强的优点。
