| description | The invention relates to a method of assembling pre-impregnated plies by local isolated polymerization of the assembly region (30) under the action of a radiation to which the resin of the prepreg is sensitive. The assembly method makes it possible in particular to produce very large sized gossamer structures (7) in the form of a concertina-folded tube which is deployed by injecting pressurized gas once into the space then stiffened by polymerization under the effect of the same radiation. The pylon concerned (7) thus comprises two structural elements (10, 20) secured end to end while at the same time maintaining its flexibility and firmness qualities.
L'invention concerne un procédé d'assemblage de plis préimprégnés par polymérisation locale ponctuelle de la zone à assembler (30) sous l'action d'un rayonnement auquel la résine du préimprégné est sensible. Le procédé d'assemblage permet notamment la réalisation de structures Gossamer (7) de grande taille, qui se présentent sous la forme d'un tube plié en soufflet qui est déployé par injection de gaz sous pression une fois dans l'espace puis rigidifié par polymérisation sous l'effet du même rayonnement. Le mât concerné (7) comprend ainsi deux éléments structurels (10, 20) solidarisées bout à bout tout en conservant ses qualités de souplesse et de solidité. |
