Abstract

Abstract Translated from French Selon le procédé on habille un mandrin creux 16 d'un boyau 17 en une matière souple et résistante, par exemple en cellophane, et on enroule autour du mandrin 16 ainsi habillé deux mèches de fibres juxtaposées 18,19 imprégnées de résine. Les mèches 18,19 sont enroulées sur une partie centrale du complexe et avec des angles de dépose différents. Venant se superposer à l'enroulement des mèches 18,19, une mèche 20 de fibres imprégnées de résine est enroulée tout le long de la gaine. L'enveloppe composite ainsi formée est séparée du mandrin 16 par introduction d'air sous pression. According to the method, a hollow mandrel 16 is coated with a hose 17 in a flexible and resistant material, for example in cellophane, and two strands of juxtaposed fibers 18,19 impregnated with resin are wound around the mandrel 16 thus dressed. The locks 18,19 are wound on a central part of the complex and with different laying angles. Coming superimposed on the winding of the wicks 18,19, a wick 20 of fibers impregnated with resin is wound along the sheath. The composite envelope thus formed is separated from the mandrel 16 by the introduction of air under pressure.
