Abstract

Procédé de drapage géodésique L’invention concerne un procédé de drapage de structures fibreuses sur une forme de drapage conique ou tronconique développable, les structures fibreuses comprenant des fibres s’étendant suivant une direction déterminée (t1, t2, t3, t4, t11, t21), le procédé étant caractérisé en ce que les structures fibreuses sont déposées sur la forme de drapage de sorte que les fibres desdites structures fibreuses se superposent à des droites de la surface développée de la forme de drapage. Figure pour l’abrégé : Fig. 6
