Title
(EN) A SYSTEM AND METHOD FOR REINFORCING COMPOSITE PIPES
(FR) SYSTÈME ET PROCÉDÉ POUR RENFORCER DES TUBES COMPOSITES
Abstract
(EN)
A process for manufacturing pipes using thermoplastic pipe and "tape" (continuous fiber, fully wetted in a similar thermoplastic as the pipe) that embeds the fibers into pipe surface. In one embodiment, an ambient temperature (72 degrees F) tape is tightly wrapped around the cold pipe in a dry environment (relative humidity below 30). An external heat source is used to heat up the entire length of the pipe causing the thermoplastic to melt and the pipe to expand due to thermal expansion. Since the fibers have less stretch than the thermal expansion of the pipe the fibers will be embedded into the molten layer of the pipe.
(FR)
L'invention porte sur un procédé pour fabriquer des tubes en utilisant un tube thermoplastique et un « ruban » (fibre continue, entièrement mouillée dans un thermoplastique analogue à celui du tube), qui implante les fibres dans la surface de tube. Dans un mode de réalisation, un ruban à température ambiante (72 degrés F) est enveloppé hermétiquement autour du tube froid dans un environnement sec (humidité relative inférieure à 30). Une source de chaleur externe est utilisée pour chauffer toute la longueur du tube en faisant fondre le thermoplastique et en amenant le tube à se dilater sous l'effet d'une dilatation thermique. Étant donné que les fibres ont une extensibilité inférieure à la dilatation thermique du tube, les fibres sont implantées dans la couche fondue du tube.
