METHOD OF MAKING A WIND TURBINE BLADE

摘要

A method of making a wind turbine blade (10) having a shell (14, 16) of varying thickness. The method comprises providing a blade mould (30), the mould defining first (32) and second zones (34); arranging layers of fibrous material (42) for forming a first part of the shell having a first thickness in the first zone (32) of the mould; arranging layers of fibrous material for forming a second part of the shell having a second thickness greater than the first thickness in the second zone (34) of the mould; and supplying resin (41) to the mould (30). The method further comprises pre-heating the mould in the first zone (32) to a first temperature, and pre-heating the mould in the second zone (34) to a second temperature greater than the first temperature before supplying the resin (41) to the mould (30).
