Abstract

On réalise une couche polymère plane (38) à cristaux liquides qui est mécaniquement quasi-isotropique, en superposant deux couches biaxialement orientées. On obtient ainsi un stratifié doté de deux parties minces à surface externe orientées dans le même sens, ainsi qu'une partie interne relativement épaisse. Ladite couche est réalisée en faisant passer un polymère à travers une série de trois rotors tubulaires (30). Lesdits rotors sont concentriques et présentent des surfaces définissant des canaux d'écoulement de polymères annulaires internes et externes. Les rotors peuvent tourner soit dans le sens de l'écoulement, soit dans le sens opposé. Dans une autre réalisation, la couche est obtenue en utilisant une matrice du genre à rainures (90) à travers laquelle s'écoule le polymère, dans un des sens possibles, tandis qu'une bande mobile (91) passe continuellement dans un sens transversal. Lesdites couches polymères ordonnées sont utiles pour la fabrication de plaquettes à circuits imprimés.
