Abstract
A shear web mould system for manufacturing a wind turbine component in form of an I-shaped shear web having a web body and a first web foot flange at a first end of the web body and a second web foot flange at a second end of the web body is described. The system comprises a central moulding portion for forming at least a part of the web body, a first moulding plate for forming at least a part of the first web foot flange, and a second moulding plate for forming at least a part of the second web foot flange. The angles of the first moulding plate and the second moulding plate relative to the central moulding portion are adjustable.
Claims8
A method for manufacturing a wind turbine blade component in form of an I-shaped shear web by use of a shear web mould system, wherein the shear web mould system comprises:
- a central moulding portion for forming at least a part of a web body;
- a first moulding plate for forming at least a part of a first web foot flange;
- and
- a second moulding plate for forming at least a part of a second web foot flange,
- wherein angles of the first moulding plate and the second moulding plate relative to the central moulding portion are adjustable, and
- wherein the method comprises the steps of:
- a) arranging a fibre-reinforcement material in a mould cavity formed by at least the central moulding portion, the first moulding plate, and the second moulding plate of the shear web mould system, wherein the angles of the first moulding plate and the second moulding plate relative to the central moulding portion are adjusted to respective desired angles prior to the arranging of the fibre-reinforcement material in the mould cavity;
- b) supplying resin to the mould cavity;
- and
- c) curing or hardening the resin in order to form said wind turbine blade component,
- wherein the desired angles of the first and second moulding plates are maintained throughout the steps of arranging the fibre-reinforcement material in the mould cavity, supplying the resin to the mould cavity, and curing or hardening the resin.
