Shifting is a method for manipulating unidirectional non-crimp fabrics that allows for a curved fiber path along with compound surface geometry. The bases for shifting is understanding unidirectional (UD) non-crimp-fabrics (NCFs) as a semi-flexible prismatic linkage and planning manipulations such that the array of linkages can conform to the surface geometry and path plan within allowable manufacturing tolerances. This has applications in structural composite components such as the current trailing edge prefabricated unidirectional components for wind turbine blades, and for future wind turbine blade designs including a curve-linear spar cap.

The disclosed subject matter provides a system and method for facilitating bonding of various turbine blade components, including trailing edge inserts, or flatbacks, to the trailing edge of a wind turbine blade. The system disclosed herein ensures a consistent force is applied from root to top thereby preventing defects, e.g. paste voids, from forming. Additionally, a consistent bonding gap can be achieved due to the consistent application of force from the root to tip of the blade.

Shifting is a method for manipulating unidirectional non-crimp fabrics that allows for a curved fiber path along with compound surface geometry. The bases for shifting is understanding unidirectional (UD) non-crimp-fabrics (NCFs) as a semi-flexible prismatic linkage and planning manipulations such that the array of linkages can conform to the surface geometry and path plan within allowable manufacturing tolerances. This has applications in structural composite components such as the current trailing edge prefabricated unidirectional components for wind turbine blades, and for future wind turbine blade designs including a curve-linear spar cap.
