Abstract

L'invention concerne une gaine qui présente une configuration tubulaire, avec une section transversale en spirale, cette gaine étant constituée d'un tissu (1) chaîne de métier de type Rachel, avec des fils (11, 12, 13, 14, 15) de fibre de verre, de fibre minérales et/ou métalliques avec un point de liage à deux barres à passettes avec le premier fil (11) de liage 2-0/0-2/2-0/0-2// et le deuxième fil (12) de liage 6-8/2-0/8-8/0-0// ou avec un point à trois barres à passettes avec le premier fil (13) de liage 2-0/0-2/2-0/0-2//, le deuxième fil (14) de liage 2-0/4-6/4-4/2-2// et le troisième fil (15) de liage 8-8/0-0/6-8/2-0//. Le tissu (1) comprend un recouvrement de résines (2). Le procédé de fabrication comprend trois phases: une phase de tissage du tissu (1) de la gaine, une phase d'enroulement transversal du tissu (1) en spirale, et une phase de mise en forme du tissu (1) de sorte qu'il conserve sa tructure tubulaire, par exemple au moyen d'une impregnation avec des résines (2).
