    摘要： A blade for a fluid dynamic machine, said blade comprising an air-foil section constituted by the superimposition upon a metal core, of a plurality of superimposed layers of composite fibrous material, said metal core having a portion which projects beyond said airfoil section in order to act as a blade attachment root, wherein said layers of composite fibrous material are arranged each with an orientation such that the angle Alpha made between the general direction of the fibres in a layer and the axis of the blade, diminishes, in absolute value, from a maximum value for the innermost layer or layers which are next to the core to a minimum value for the outermost layer or layers which are next to the surface of the airfoil section.
