Abstract: A wind turbine blade bushing system for arrangement in a root end of a wind turbine blade is described. The wind turbine blade bushing system comprises a threaded element for retaining a mounting bolt for a wind turbine blade, the threaded element being formed from a first material; and an anchor element for arrangement at the root end of the wind turbine, wherein the anchor element acts to at least partly retain the threaded element in the wind turbine blade, the anchor element being formed from a second material. The first material has a higher strength and higher fracture toughness than the second material.

Abstract: A hybrid material mat for use in the manufacture of fibre-composite articles, in particular parts for wind turbine blades, is described. The mat comprises a plurality of glass fibre rovings provided on top of a relatively thin planar substrate of carbon fibres. Such a hybrid mat construction provides for an improvement in the structural properties of a component manufactured using the mat, as well as allowing for ease of handling and manufacturing of both the mat itself and the component.
