A method of producing a composite structure consists of winding a resin impregnated filament tow onto a former or formers having surfaces which correspond with a portion of the finished article, removing the fibre sheets from the former or formers, and placing them in a mould which corresponds in shape to that of the complete article, and pressing the fibre within the mould to consolidate the finished article.

A method for making a composite structure, comprising: cutting into sections a pattern of an article having an annular shape and a compound curvature, securing two of said sections back-to-back to make at least one former having plural shaping surfaces, each of which surfaces corresponds to a portion of the surface of said composite structure, winding at least one filament onto the surface of at least one said former to produce at least one layer of filament to reinforce a curable resin matrix and thereby form at least one filament-reinforced resin layer, dividing said resin layer into at least two preforms and removing the reinforced resin preforms from the at least one former and placing plural such preforms upon the surface of a mold, which surface corresponds to the completed shape of the finished composite structure, covering the surface of the mold, and subsequently exerting pressure upon the reinforced resin layers to consolidate them prior to curing the resin, and curing said resin.
