A JOINING METHOD FOR WIND TURBINE BLADE SHELLS

摘要

A method of manufacturing a wind turbine blade is described, the blade being formed from at least a pair of blade shells being joined together. For at least a portion of the wind turbine blade, the blade shells are joined by an overlamination applied between the edges of the blade shells, thereby substantially reducing or eliminating the need for a structural adhesive to join the blade shells, particularly in the area of the leading edge of the blade or the root region of the blade trailing edge. The overlamination can be formed from the same material as the blade shells themselves, thereby minimising the possibility of structural faults or cracks due to differences in materials or stiffness levels at the interface between the blade shells.

1. A method of manufacturing at least a portion of a wind turbine blade, wherein the method comprises the steps of:
providing a first blade shell having a first edge, providing a second blade shell having a second edge, and joining said first blade shell to said second blade shell along at least a portion of said first edge and said second edge by providing an overlamination extending between said first edge and said second edge, wherein said joining is performed substantially without a structural adhesive, and wherein said overlamination is applied to external surfaces of said first edge and said second edge.
