Abstract
La présente invention a pour objet un procédé de fabrication par extrusion-traction d'un tube de résine renforcée de fibres, suivant lequel on dépose sur un mandrin 2 des fibres de renforcement longitudinales 4A et on enroule des éléments fibreux continus de renforcement sur les fibres longitudinales, de manière à constituer une matrice de fibres, on refoule de la résine liquide par des ouvertures 2B réparties sur le pourtour du mandrin de manière à revêtir la matrice, on entraîne cette matrice revêtue vers un poste de durcissement 7, et on exerce sur le tube rigide termine une traction dirigée vers le haut, par des moyens 8. L'invention a également pour objet un dispositif pour la mise en oeuvre de ce procédé et les tubes obtenus.
