Abstract
A method of manufacturing a wind turbine rotor blade is provided. Anticipated primary load paths within the rotor blade are predicted. Fibres of reinforcing material are dispensed onto a mould, having an orientation pattern of the fibres which is selected in dependence on the predicting step. Resin is also dispensed into the mould. A wind turbine rotor blade is provided. The blade comprises fibres of reinforcing material which are embedded in resin. The fibres are short, say in the range of 5 to 200 mm, and are orientated in dependence on an anticipated structural loading pattern of the rotor blade.

Method of manufacturing a wind turbine rotor blade, the method comprising the steps of:
- predicting anticipated primary load paths within the rotor blade;
- dispensing fibres of reinforcing material onto a mould, an orientation pattern of the fibres being selected in dependence on the predicting step;
- dispensing resin into the mould;
- and
- curing the rotor blade in the mould.
A wind turbine rotor blade comprising fibres of reinforcing material embedded in resin, wherein the lengths of the fibres are in the range of 5 to 200 mm and are orientated in dependence on an anticipated structural loading pattern of the rotor blade.
