Abstract
In a method of manufacturing 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.
