ABSTRACT:
The invention concerns a method for manufacturing a blade (10), in which at least the composite base structure (15) of the blade (10) is manufactured in a pultrusion process (20) by pulling fibers (11) through at least an impregnation stage (12) and a curing stage (14), the base structure (15) is equipped with at least one wear area (16.1, 16.2), and the said blade (10) is detached from a blade blank (22) formed of a base structure (15) and a wear area (16.1, 16.2). The wear area of the blade (10) is formed of an edge-structure part (16.1, 16.2) protruding out side the edge of the base structure (15). In addition, the invention also concerns a corresponding blade and part components for manufacturing a blade according to the invention.
