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.
