Title
(EN) NANOTUBE-ENHANCED INTERLAYERS FOR COMPOSITE STRUCTURES
(FR) COUCHES INTERMÉDIAIRES AMÉLIORÉES PAR DES NANOTUBES POUR STRUCTURES COMPOSITES
Abstract
(EN)
Carbon nanotube interlayer assemblies, methods of manufacturing carbon nanotube interlayer assemblies, and methods of manufacturing composite parts with carbon nanotube interlayer assemblies are disclosed herein. In one embodiment, a method of manufacturing a composite structure in accordance with an embodiment of the invention includes producing a plurality of carbon nanotubes on one or both sides of a substrate, and attaching the substrate to a first fiber layer. The method can further include positioning a second fiber layer adjacent to the first fiber layer to position the plurality of carbon nanotubes between the first and second fiber layers. The method can additionally include infusing the first and second fiber layers with resin, and curing the resin. In one embodiment, the carbon nanotube substrate can be attached to the first fiber layer by melt-bonding. In another embodiment, the carbon nanotube substrate can be attached to the first fiber layer with stitches.

Cette invention se rapporte à des ensembles de couches intermédiaires à nanotubes de carbone, à des procédés de fabrication d'ensembles de couches intermédiaires à nanotubes de carbone, et à des procédés de fabrication de pièces composites ayant des ensembles de couches intermédiaires à nanotubes de carbone. Dans un mode de réalisation, un procédé de fabrication d'une structure composite, conformément à un mode de réalisation de l'invention, comprend la production d'une pluralité de nanotubes de carbone sur un ou les deux côtés d'un substrat, et la fixation du substrat à une première couche de fibres. Le procédé peut en outre comprendre le positionnement d'une deuxième couche de fibres de manière adjacente à la première couche de fibres afin de positionner la pluralité de nanotubes de carbone entre les première et deuxième couches de fibres. Le procédé peut de plus comprendre l'injection d'une résine dans les première et deuxième couches de fibres, et le durcissement de la résine. Dans un mode de réalisation, le substrat à nanotubes de carbone peut être fixé à la première couche de fibres par liaison par fusion. Dans un autre mode de réalisation, le substrat à nanotubes de carbone peut être fixé à la première couche de fibres par des points.
