Abstract

A method and a manufacturing line (30) for manufacturing wind turbine blades having a composite shell structure comprising a matrix material and a fibre reinforcement material by use of a resin transfer moulding process. The method comprises a manufacturing line (30), where wind turbine blades are formed in a number of moulds (40, 50, 60), each of the number of moulds (40, 50, 60) comprising at least a first mould part (41, 51, 61) comprising a first mould cavity (42, 52, 62). The manufacturing line (30) further comprises a number of separate work stations (31, 32, 33), where separate manufacturing steps are carried out. The method comprises the following steps: a) arranging the fibre reinforcement material in a first mould cavity (42) of a first mould part (40) at a first work station (31), b) moving the first mould part (40) with the fibre reinforcement materials by use of conveying means to a second work station (32) having a different position than the first work station (31), and c) supplying a curable matrix material into the first mould cavity (42) of the first mould part (41) at the second work station (32). The manufacturing line (30) comprises a number of moulds (40, 50, 60), the number being greater than one, where wind turbine blades (45, 55, 65) are formed in, each of the number of moulds (40, 50, 60) comprising at least a first mould part (41, 51, 61) comprising a first mould cavity (42, 52, 62). Each of the number of moulds (40, 50, 60) being movable along the manufacturing line (30) by conveying means.
