NOVELTY - Manufacture of wind turbine rotor blade comprises predicting anticipated primary load paths within the rotor blade; dispensing fibers (40) of reinforcing material onto a mold (20), where orientation pattern of the fibers is selected in dependence on the predicting step; dispensing resin (60) into the mold; and curing the rotor blade in the mold.    USE - Method of manufacturing wind turbine rotor blade for wind turbine installation (claimed).    ADVANTAGE - By dispensing fibers directly into the mold in an orientated fashion, reflecting the anticipated loading of the finished component in use, an improved rotor blade can be manufactured. The method can be automated which, in turn, improves the accuracy, reliability, and speed of manufacture and quality of the final product. Automation enables complete control of the orientation of the fibers such that optimized structural design of the rotor blade component can be achieved. The blade itself comprises an optimal fiber to resin ratio, which enhances the structural integrity of the blade without increasing its weight. As fibers are placed directly in the mold, kinks and folds of the fibers are avoided such that imperfections or flaws in the blade are avoided. Very high material deposition rates can be achieved using the method, such that large components e.g. wind turbine rotor blades or its parts can be manufactured rapidly. By using a multitude of individual, short fibers in place of sheets of pre-formed, interwoven, prepreg, the likelihood of introducing structural defects due to the presence of folds and/or wrinkles is considerably reduced, if not eliminated.
