A method of manufacturing fiber-reinforced parts, such as blades, for wind power plants, whereby a number of layers () of material comprising fiber, such as glass fiber mats, are arranged on a curved surface () of an elongated () open mold () wherein each layer () of material is arranged on said curved surface () as pre-shaped mats () having a form substantially corresponding to an intended area of application such that any need for further modification of or cutting in said material is substantially eliminated.

Method of manufacturing a laminated part from fibre material

The present invention relates in general to a method of manufacturing fibre-reinforced parts for a wind power plant, such as a blade, in an open mould. More specifically the invention relates to a process step of applying at least one layer of gelcoat on a interior surface of said open mould prior to arranging at least one layer of material comprising fibre and to an arrangement that can be used in performing said method. The process step comprises to apply the gelcoat from a first end portion of the mould and to a second end portion of the mould and to cover the open mould from said first end portion to said second end portion gradually as gelcoat is applied. The arrangement comprises means for applying gelcoat to the interior surface of the mould () and a covering means () arranged to gradually cover the open mould () as gelcoat is applied.

Method of applying gelcoat and an arrangement performing said method

A method and a manufacturing line for manufacturing wind turbine blades having a composite shell structure comprising a matrix material and a fiber reinforcement material by use of a resin transfer moulding process. The method comprises a manufacturing line, where wind turbine blades are formed in a number of moulds. Each number of moulds comprising at least a first mould part comprising a first mould cavity. The manufacturing line further comprises a gantry means movable along the manufacturing line. The method comprises the following steps: a) arranging fiber reinforcement material in the first mould cavity of a first mould using the gantry means, b) moving the gantry means along the manufacturing line to a second mould, c) supplying curable matrix material into the first mould cavity of the first mould, while substantially simultaneously arranging fiber reinforcement material in the first mould cavity of a second mould using the gantry means. The manufacturing line comprises a plurality of moulds for forming wind turbine blades. Each of the number of moulds comprising at least a first mould part comprising a first mould cavity.
