Abstract

Abstract Translated from French Selon le procédé de réalisation de parois en fibres de carbone, déformables élastiquement par rapport à une forme d'équilibre, on utilise une texture souple de fibres de carbone, on impose à cette texture la forme d'équilibre (1") en la maintenant contre la surface d'un outil correspondant à ladite forme et on fige la texture de cette forme d'équilibre par formation autour des fibres d'une gaine mince de carbone pyrolitique infiltré en profondeur en phase vapeur à haute température. On peut imposer à la texture une forme plane par utilisation de plateaux de maintien. On peut partir d'une gaine tressée qu'on comprime ou étire axialement autour d'un mandrin (2). On peut utiliser un ruban tissé qu'on enroule en pseudo-spirale conique applicable aux valves cardiaques. According to the process for producing carbon fiber walls, elastically deformable relative to an equilibrium shape, a flexible texture of carbon fibers is used, this equilibrium shape (1 ") is imposed on this texture by maintaining it against the surface of a tool corresponding to said shape and the texture of this equilibrium shape is frozen by formation around the fibers of a thin sheath of pyrolytic carbon deeply infiltrated in the vapor phase at high temperature. texture a flat shape by using retaining plates. You can start with a braided sheath that is compressed or stretched axially around a mandrel (2). You can use a woven ribbon that is wound in a conical pseudo-spiral applicable to heart valves.
