Abstract

Use of a composite article as spar component, the composite article comprising a panel (10) comprising a layer of a foamed plastic material (1), mounted between an upper (2) and a lower (3) layer of a fibrous reinforcing material, the panel (10) being impregnated with a resin material, characterised in that the foamed plastic material (1), the upper (2) and lower (3) layer of fibrous reinforcing material are fastened to each other by means of reinforcing fibrous material which extends in Z-direction of the panel (10).
