A method of forming a composite structure comprising: forming a substantially rigid former (34) comprising a hollow region; arranging a spacer (37) over the hollow region to increase the outer circumference of the former in the hollow region; wrapping the former and the spacer with reinforcing fibre; withdrawing the spacer (37); and coating the surface of the hollow region with the wrapped fibre.
L'invention concerne un procédé de formation d'une structure composite comprenant les étapes consistant à : façonner un gabarit sensiblement rigide comportant une zone creuse; mettre en place un élément d'espacement sur la zone creuse afin d'augmenter la circonférence extérieure du gabarit dans la zone creuse; envelopper le gabarit et l'élément d'espacement de fibres de renforcement; retirer l'élément d'espacement; et enduire la surface de la zone creuse des fibres enveloppées.
