Abstract

Abstract Translated from French L'invention concerne la fabrication directe d'un fil ou ruban composite constitué de fibres de renforcement continues et d'une matière organique thermoplastique. L'invention consiste, dans une première phase, à étirer des fibres de renforcement à partir d'une matière à l'état fondu, telle que du verre, et simultanément, à entraîner ou à extruder une matière organique thermoplastique, les trajets suivis par les fibres de renforcement et la matière organique convergeant l'un vers l'autre ; dans une deuxième phase, à réunir ladite matière organique et lesdites fibres en au moins un fil ou ruban composite entraîné mécaniquement. Le fil ou ruban composite est utilisé directement pour fabriquer des pièces renforcées. The invention relates to the direct manufacture of a composite wire or ribbon made up of continuous reinforcing fibers and of an organic thermoplastic material. The invention consists, in a first phase, of drawing reinforcing fibers from a molten material, such as glass, and simultaneously, entraining or extruding a thermoplastic organic material, the paths followed by reinforcing fibers and organic matter converging towards each other; in a second phase, bringing together said organic material and said fibers into at least one mechanically driven composite wire or ribbon. The composite wire or tape is used directly to make reinforced parts.
