A facility for manufacturing a rotor blade of a wind turbine is provided. The facility includes an injection machine for injecting an injection material into a mold to form the rotor blade, a movable tank system for accommodating precursor material to be supplied to the injection machine for preparing the injection material, wherein the movable tank system has wheels for moving the tank system. Further, a method for setting up a facility and a method for manufacturing a rotor blade are described.

A mold assembly includes a first mold part with a first mold opening and a second mold part with a second mold opening. The first mold part and the second mold part are separate parts. A rotating device rotates the second mold part from a position in which the second mold opening faces upwards to a position in which the second mold opening faces downwards. A moving device moves the first mold part and/or the second mold part relative to each other such that the second mold part is located above the first mold part. A closing device moves the first mold part and the second mold part towards each other with the first and second mold openings facing each other until the first and second mold parts engage. Further, a method of closing a mold assembly is provided.

A method in which a fibre material is laid on a mould surface resembling a negative image of a fibre reinforced structure to be produced. Layering the fibre material on the mould surface includes laying rovings of the fibre material on the mould surface or on a fibre material already laid on the mould surface and applying an low pressure to a space between the rovings and the mould surface.
摘要:
A mould for building up a blade is described. The mould has an inner surface for supporting a plurality of layers forming the blade. The mould also has at least one inlet for injecting a matrix material which penetrates the layers to build up the blade. The at least one inlet is integrated into the inner surface of the mould.

A blade for a wind turbine includes at least one heating mat for generating heat, wherein the heating mat is mounted at an outer surface of the blade. The blade further includes at least one through-hole running from an inner space of the blade to the outer surface of the blade. The blade further has at least one conductive element, wherein the conductive element is electrically coupled to the heating mat. The conductive element is inserted in the through-hole for generating an electric connection between the inner space and the outer surface.

A mold assembly comprises a first (1) and a second mold part (2) said mold assembly further comprising a hinge mechanism optionally detachably connected to the two mold parts. The hinge mechanism has at least a first (5) and a second hinge axis (6) connected by means of at least one connectina arm and extending with a mutual distance substantially parallel to the two mold parts (1, 2) in the longitudinal direction of the mold so that the mold parts (1, 2) are pivotable with respect to each other between a first, open position, where the two mold parts (1, 2) are located adjacent each other with a mutual distance and with the openings of the two mold parts (1, 2) facing substantially upwards, and a second position, where the first mold part (1) is rotated around the first hinge axis (5) by means of a first drive means (7) so that the opening of said first mold part faces substantially to the side and towards the second mold part (2), and a third position, where the first mold part (1) is further rotated around the second hinge axis (6) by means of a second drive means (8) so that the opening of said first mold part faces substantially downward towards the opening of the second mold part (2).
摘要:
A method for controlling a resin flow in a closed mould cavity during a vacuum assisted resin transfer moulding process is disclosed. The used closed mould cavity includes at least one resin inlet and a number of resin outlets. Each resin outlet is operatively connected to an inlet of a container. Each container includes an outlet which is operatively connected to a vacuum pump. The method includes evacuating the closed mould cavity through the resin outlets by the vacuum pump, injecting liquid resin into the closed mould cavity, measuring the resin fill level in each container during the injection of liquid resin into the closed mould cavity and adjusting the applied pressure at each container outlet depending on the measured resin fill level in the particular container.
