A TUBULAR ELEMENT, THE RELATED METHOD AND TOOLS TO PRODUCE IT

摘要

The present invention provides a method of manufacturing a tubular element (2) for a wind turbine blade of a reinforced polymeric material. The method provides a female mould (1) with a shape defining inner surface (3), and a core (7) being adapted to be arranged in the tubular cavity (5) of the female mould (4). Layers of fabric (6) of a fibre material is arranged along the lower inner surface of the lower mould portion, followed by arranging the core in the tubular cavity, and overlapping of end portions of the layers of fabric t form a closed tubular structure of the tubular element. Subsequently, the female mould is closed, and the layers of fabric and a resin are processed to provide the tubular element of a reinforced polymeric material.
