Method of manufacturing pre-bent wind turbine blades
 
Olesen et al of LM Glasfiber A/S, Denmark, manufactured a blade shell half of a pre-bent wind turbine blade by means of vacuum-assisted resin transfer moulding (VARTM), a fibre lay-up is placed on a mould surface and a distribution layer is placed above the fibre lay-up.  At least one segmentation area is provided in the distribution layer by providing at least one transversely extending flow barrier in the distribution layer preventing or restricting longitudinal resin flow to the distribution layer.  A longitudinally extending first feed channel is placed above the distribution layer.  The first feed channel is divided into at least two feed channel sections, a feed channel section being arranged in each distribution layer segment. A vacuum bag is arranged on top of the mould part to define a mould cavity. The mould cavity is evacuated and liquid resin is supplied to each feed channel section through a resin inlet to fill the mould cavity and impregnate the fibre lay-up. (RDC 7/25/2012)
