Cited inInternational search[XAI]WO2012004193  (HOLDING DEPESTELE SOC [FR], et al) [X] 1,7,10 * "Les deux nappes tissées (2, 3) sont constituées par des entrelacements de rubans de fibres de lin non coupées, alignées parallèlement entre elles, d'une largeur de quelques millimètres. Elles peuvent également associer d'autres fibres telles que des fibres de polypropylène, ou encore à base d'acide polylactique (PLA). Les fibres ne sont pas soumises à une torsion afin de conserver les qualités mécaniques des fibres longues. La liaison entre la nappe non-tissée (1 ) et les nappes tissées (2, 3) est réalisée par aiguilletage. La préforme peut être stockée et expédiée sous forme de rouleaux. Elle est utilisée pour fabriquer des plaques ou des pièces de forme quelconque. Il est possible de former des courbures avec des rayons faibles. Les fibres de lin glissent alors les unes par rapport aux autres, parallèlement entre elles. L'ensemble est ensuite mouillé avec une solution aqueuse, de l'eau ou de la vapeur d'eau afin de dissoudre la pectine entourant les fibres de lin. Le chauffage active la dissolution et provoque ensuite l'évaporation de l'eau, ce qui conduit la pectine à se reconfigurer pour lier les fibres constituant les nappes de tissé (2, 3) et de non tissé (1 ). L'ensemble est mis sous pression à des pressions comprises entre 1 et 15 bars, ce qui produit un compactage de l'ensemble." * [A] 2-4,8,9,11,12 [I] 5,6;

 [X]WO0187571  (IHC REHABILITATION PRODUCTS [US], et al) [X] 1 * "As shown in FIGS. 11 and 12, the conduit 212 is placed on the structure 210, where the lower surface 214 of a lower portion 216 of the conduit 212 is in contact with an outer surface 218 of the structure 210. The lower portion 216 of the conduit 212 is commonly referred to as the"bell portion" Referring to FIG. 13, the composite structure 210 includes an upper section 220 and a lower section 222. The upper section 220 has a fiber architecture 244 that is formed from a plurality of commingled conductive fibers 226 impregnated with a resin. Preferably, the conductive fibers 226 are carbon fibers because of their high strength. The resin should have high strength and high temperature characteristics to withstand the harsh operating environment that is consistent with conduit formation and construction. The resin can be thermoplastic, thermosetting, fluorocarbon, or fluorosilicone resin. A number of different mechanical consolidation techniques can be used loosely combine the conductive fibers 226 and form the fiber architecture 224. These consolidation techniques include weaving, braiding, knitting, needling (needle punching), or stitch-bonding. In addition to the mechanical consolidation, the fiber architecture 224 can be formed by chemically consolidating the fibers 226 under vacuum pressure. Regardless of the consolidation technique, the resulting fiber architecture 224 should be an open weave, or loose weave." *;
