Title
(EN) UNITIZED COMPOSITE FABRICS WITH CROSS MACHINE WAVE-LIKE SHAPING AND METHODS FOR MAKING SAME
(FR) tissu composite intégré à ondulations dans le sens transversal de la machine et procédés pour le réaliser
Abstract
(EN)
A manufacturing method for producing a unitized composite material has been discovered. An assembly of loose fibers or fiber and fabric combinations is formed where at least one of the layered elements contains a bondable material such as a thermally sensitive bonding fiber. The un-bonded layered assembly is shaped into a wavy form having a repeating wave-like pattern of the desired amplitude and wavelength. The amplitude and wavelength of the repeating waves can be altered such as by changing the relative speeds of a transfer device and an oven wire and the height of the transfer device relative to the height of the oven wire using simple machinery control settings. The shaped assembly is subsequently bonded in an oven or other activation step preserving the wave-like shaping when cooled or removed from the activation effect.

L'invention concerne un procédé de fabrication d'un matériau composite intégré. On forme un ensemble de fibres lâches ou un ensemble de combinaisons de fibres et de tissu dans lequel au moins un des éléments stratifiés contient un matériau qui peut être lié, par exemple une fibre de liaison sensible à la chaleur. Dans l'ensemble stratifié non lié, on forme une ondulation qui présente un motif répété d'amplitude et de longueur d'onde souhaitées. L'amplitude et la longueur d'onde des ondulations répétées peuvent être modifiées par exemple en changeant les vitesses relatives d'un dispositif de transfert et d'un fil de four et la hauteur du dispositif de transfert par rapport à la hauteur du fil de four en utilisant des réglages simples de contrôle de la machinerie. L'ensemble formé est ensuite lié dans un four ou par une autre étape d'activation qui conserve la forme ondulée lorsque le tissu est refroidi ou n'est plus exposé à l'effet d'activation.
