Abstract

L'invention concerne un article en forme de flexible présentant au moins la structure de couches suivante : - une couche interne (01) et une couche externe (05), qui sont chacune à base d'une matière polymère avec des propriétés élastiques, et — une première couche support de solidité (02) et une seconde couche support de solidité (03), qui sont noyés entre la couche interne (01) et la couche externe (05) et sont chacune à base d'un matériau textile, la première couche support de solidité (02) étant en liaison avec la couche interne (01) et la seconde couche support de solidité (03) étant en liaison avec la couche externe (05). L'article en forme de flexible selon l'invention se caractérise par le fait que l'allongement de la première couche support de solidité (02) est supérieur à l'allongement de la seconde couche support de solidité (03). Entre la première couche support de solidité (02) et la seconde couche support de solidité (03), qui sont conçues à chaque fois en particulier sous forme de treillis textile, est disposée de préférence une couche intermédiaire (04) à base d'une matière polymère avec des propriétés élastiques. L'article en forme de flexible est en particulier un flexible haute pression très résistant.
