Disclosed is a reinforced thermoplastic pipe, comprising a thermoplastic polymer inner tube, a thermoplastic polymer outer tube and a reinforcing fabric between the thermoplastic polymer inner tube and the thermoplastic polymer outer tube. The reinforcing fabric comprises thermosettable thermoplastic polymer weft yarns and unidirectionally woven warp yarns. The warp yarns are twisted into twisted cords. Disclosed is also a process of making the reinforced thermoplastic pipe.
L'invention porte sur un tuyau en matière thermoplastique renforcé, comprenant un tube interne en polymère thermoplastique, un tube externe en polymère thermoplastique et un tissu de renforcement entre le tube interne en polymère thermoplastique et le tube externe en polymère thermoplastique. Le tissu de renforcement comprend des fils de trame en polymère thermoplastique thermodurcissable et des fils de chaîne tissés de manière unidirectionnelle. Les fils de chaîne sont torsadés pour former des cordons torsadés. L'invention porte également sur un procédé de fabrication du tuyau en matière thermoplastique renforcé.
