Abstract
A shear web flange (36) for a shear web (32) of a wind turbine blade (18) is described. The flange (36) extends longitudinally and comprises a bonding surface (50) for bonding to an inner surface of a wind turbine blade (18). One or more protruding features (52a, 52b) protrude from the bonding surface (50). A method of making such a shear web flange (36) is also described as are a shear web (32) for a wind turbine blade (18), a wind turbine blade (18) and a method of making a wind turbine blade (18).
Claims22
A wind turbine blade shear web comprising:
- a web panel having first and second edges;
- and
- first and second flange structures, each flange structure including:
- a flange extending longitudinally and including a bonding surface for bonding to an inner surface of a wind turbine blade, the bonding surface having one or more protruding features configured to extend toward the inner surface of the wind turbine blade;
- wherein the protruding features protrude from the bonding surface by approximately 0.5 to 5 mm;
- and
- an upstand extending from a surface of the flange opposite the bonding surface of the flange,
- wherein at least a portion of the upstand of the first and second flange structures is positioned inside the web panel at respective first and second edges.

A wind turbine blade shear web comprising:
- a flange extending longitudinally and including a bonding surface for bonding to an inner surface of a wind turbine blade, the bonding surface having one or more longitudinally extending peripheral ridges configured to extend toward the inner surface of the wind turbine blade,
- wherein the peripheral ridges protrude from the bonding surface by approximately 0.5 to 5 mm;
- wherein an upstand extends from a surface of the flange opposite the bonding surface of the flange,
- wherein a central ridge is located substantially centrally between first and second longitudinal edges of the flange, and
- wherein the central ridge and the upstand are aligned in a lateral direction.
