Abstract: The invention relates to a method of manufacturing fibre-reinforced parts for a wind power plant such as eg a blade, wherein the method comprises laying out a first, outermost layer of film in the interior surface of an open mould; following which different layers are arranged on top of the first layer, comprising layers of fiber material; and wherein resin is applied for joining the laid-out layers to each other. By use of a film for the outermost layer a moulding process results that provides a major improvement of the working conditions. A further advantage is also that, compared to the use of gelcoat, a surface is accomplished which is more resistant to physical influences in the form of eg cyclical stresses on the element. The invention also relates to a fiber-reinforced part for a wind power plant, eg a blade, wherein the part is structured from a first, outermost layer, and also to a blade for a wind power plant and comprising a fiber-reinforced part according to the invention.

Abstract: Apparatus and method of producing fiber composite moldings by means of vacuum infusion applying a mold with a mold cavity, a plurality of inlet channels (3, 21, 22) communicating with the mold cavity and a polymer source (7) with liquid polymer, a plurality of vacuum channels (2) communicating with the mold cavity and a vacuum source (10), where fiber material (14) is inserted into the mold cavity prior to the process of filling said mold, and where a negative pressure is generated in the vacuum channels (2) and thus in the mold cavity with the result that liquid polymer is drawn from the polymer source (7) via the inlet channels (3, 21, 22) into the mold cavity. One or more of the inlet channels (3, 21, 22) can also communicate with a vacuum source, and/or one or more of the vacuum channels (2) can also communicate with a polymer source (7).

Abstract: A mould assembly includes a first mould part (2) and a second mould part (4) for moulding a wind turbine blade of fibre-reinforced polymer. The assembly has a hinge mechanism (6) with a hinge line (7) extending parallel to the two mould parts in the longitudinal direction of the mould to allow turning of the mould parts in relation to each other between an open position and a closed position. It also has a displacement mechanism for a rectilinear translational movement of the second mould part (4) between a partially closed position and a completely closed position. The displacement mechanism has guide rods (8) including drives for displacing them and thus for moving the two mould parts between the partially closed and completely closed positions.

Abstract: Mould assembly including a first mould part (2) and a second mould part (4) for moulding a substantially elongated, closed profile member, in particular a wind turbine blade of fibre-reinforced polymer, said mould assembly including a hinge mechanism (6) with a hinge line (7) extending parallel to the two mould parts in the longitudinal direction of the mould to allow turning of the mould parts in relation to each other between an open position and a closed position. The mould assembly includes displacement means for a rectilinear translational movement of the second mould part (4) between a partially closed position and a completely closed position. The displacement means are formed of guide rods (8) including drive means for displacing the guide rods (8) and thus for moving the two mould parts between the partially closed and completely closed positions. The invention further relates to a method of using the mould assembly.
