Title
(EN) METHOD FOR PRODUCING FIBROUS MATERIALS PRE-IMPREGNATED WITH A THERMOHARDENABLE POLYMER
(FR) PROCEDE DE FABRICATION DE MATERIAU FIBREUX PRE-IMPREGNE DE POLYMERE THERMODURCISSABLE
Abstract
(EN)
The invention relates to a method for producing a fibrous material comprising carbon fibres or glass fibres or plant fibres or polymer-based fibres, that are used alone or in a mixture, and are impregnated by a thermohardenable polymer using a mixture containing a hardener and carbon nanofillers, such as carbon nanotubes (CNT). According to the invention, a mixture containing said nanofillers, such as CNTs, and the hardener is used to introduce said nanofillers into the fibrous material. A continuous production line (L) for producing the material in the form of at least one calibrated and homogeneous strip (20) of reinforcing fibres impregnated with a thermohardenable polymer, comprises the device (100) for arranging two series of fibres (1, 2) used to form a strip in such a way as to arrange the two series of fibres such that they are brought into contact with each other by means of two calendering devices.

L'invention concerne un procédé de fabrication d'un matériau fibreux comportant des fibres de carbone ou de fibres de verre ou de fibres végétales ou de fibres à base de polymère, utilisées seules ou en mélange, imprégnées par un polymère thermodurcissable en utilisant un mélange contenant un durcisseur et des nanocharges carboniques, telles que les nanotubes de carbone (NTC). Selon l'invention, on utilise un mélange contenant lesdites nanocharges comme les NTC et le durcisseur pour introduire lesdites nanocharges, dans le matériau fibreux Une ligne (L) de formation continue du matériau sous forme d'au moins une bande (20) calibrée et homogène en fibres de renfort imprégnées de polymère thermodurcissable comprend le dispositif (100) de mise en place de deux séries de fibres (1,2) utilisées pour former une bande, de manière à disposer les deux séries de fibres au contact l'une de l'autre à l'aide de deux dispositifs de calandrage.
