Title (EN) MULTIWALL SHEET AND METHODS OF USING THE SAME
(FR) FEUILLE À PAROIS MULTIPLES ET SES PROCÉDÉS D'UTILISATION
Abstract:
(EN) In one embodiment, a multiwall sheet can comprise: a first wall; a second wall; an intermediate wall disposed between the first wall and the second wall; a first set of ribs disposed between the first wall and the intermediate wall; a second set of ribs disposed between the second wall and the intermediate wall; a cavity disposed between adjacent ribs; wherein the multiwall sheet is configured to expand and/or collapse when a mechanical force (preferably shear force) is applied to the intermediate wall. Preferably the multiwall sheet has a flexural rigidity of greater than or equal to 10 N/mm.
(FR) Selon un mode de réalisation, cette invention concerne une feuille à parois multiples, comprenant : une première paroi ; une seconde paroi ; une paroi intermédiaire disposée entre la première paroi et la seconde paroi ; un premier ensemble de nervures disposées entre la première paroi et la paroi intermédiaire ; un second ensemble de nervures disposées entre la seconde paroi et la paroi intermédiaire ; une cavité disposée entre des nervures adjacentes. La feuille à parois multiples est configurée pour se déployer et/ou se replier lorsqu'une force mécanique (de préférence une force de cisaillement) est appliquée sur la paroi intermédiaire. De préférence, la feuille à parois multiples présente une rigidité à la flexion supérieure ou égale à 10 N/mm.
