Abstract
A method of manufacturing composite blades comprises: laying up a pre-impregnated composite material to form a pre-impregnated composite structure; vacuum bagging the pre-impregnated composite structure between a first pressure plate and a second pressure plate; consolidating and curing the pre-impregnated composite structure to form a fiber-reinforced composite structure; and machining an overlap portion of the fiber-reinforced composite structure to form a first fiber-reinforced composite blade and a second fiber-reinforced composite blade.
