Abstract

Procédé de fabrication d'une structure comprenant au moins deux couches tubulaires. Il consiste à bobiner sur un gabarit une couche intérieure lisse 30 constituée de filaments imprégnés de résine, puis des bandes de matière souple, intercalées avec d'autres couches de filaments, de manière à donner à ces couches une forme ondulée. L'ensemble est ensuite recouvert d'une couche lisse extérieure 38. Domaine d'application : production de tubes légers et résistants.A method of manufacturing a structure comprising at least two tubular layers. It consists of winding on a template a smooth inner layer 30 consisting of resin-impregnated filaments, then strips of flexible material, interposed with other layers of filaments, so as to give these layers a wavy shape. The assembly is then covered with an outer smooth layer 38. Field of application: production of light and resistant tubes.
