Abstract
A method of manufacturing a root ring for a wind turbine blade comprising winding metal sheet material onto a mandrel to form a metal section proximate a hub end of the root ring. Sheet fibre material is also wound onto the mandrel to form a fibre section of the root ring proximate a tipwards end of the root ring. The metal sheet material is interleaved with the sheet fibre material to form a transition section of the root ring between the metal section and the fibre section.

A method of manufacturing a root ring for a wind turbine blade, the root ring comprising a hub end and a tipwards end, the root ring extending in a spanwise direction from the hub end to the tipwards end, the method comprising:
- winding metal sheet material onto a mandrel to form a metal section proximate the hub end of the root ring;
- winding sheet fiber material onto the mandrel to form a fiber section proximate the tipwards end of the root ring;
- and
- interleaving the metal sheet material with the sheet fiber material to form a transition section of the root ring, wherein the transition section is located between the metal section and the fiber section.
