Abstract

L'invention concerne un procédé de production d'un contenant composite présentant une forme et une résistance voulues. Un préimprégné de filaments est enroulé autour d'une doublure pour former une couche fibreuse (S4). La couche fibreuse est chauffée depuis l'intérieur de la doublure afin de réduire la viscosité de la résine infiltrée dans les fibres enroulées, à une valeur inférieure à la viscosité mesurée avant l'enroulement autour de la doublure (S5). La couche fibreuse est ensuite chauffée depuis l'intérieur de la doublure afin de traiter progressivement la résine de la couche fibreuse, depuis la surface de la doublure vers l'extérieur de celle-ci (S6). Dans un autre mode de réalisation, un préimprégné de filaments est enroulé autour d'une doublure afin de former une couche fibreuse, et la couche fibreuse est chauffée depuis l'intérieur de la doublure. La résine infiltrée dans les fibres enroulées est ainsi progressivement traitée depuis la surface de la doublure vers l'extérieur de celle-ci, et produit de la chaleur à mesure que le traitement est mis en oeuvre.
