Method of producing large hollow parts based on composite materials |
摘要 |
The invention relates to a method of producing large parts based on composite materials, such as the roots of blades for wind generators. The inventive method comprises the following steps consisting in: helically winding a band of fibre- and resin-based composite material around a mould; applying a removable protective sheet to the surface of the body; applying a heat-shrinkable strip to the sheet; compacting the laminate thus formed under a vacuum; curing the resin; aligning the cured body, machining the transverse surface to be applied to the blade and forming axial housings in said surface; and positioning and affixing inserts in the axial housings in order to secure the blade. |
