摘要:
The present invention relates to a method for the manufacture of pressure-resistant gas and/or liquid tight containers made from thermoplastic materials. To this end the method comprises the following steps : providing a removable external mandrel around a neckpiece, followed by providing at the inside of such mandrel a thermoplastic material for the manufacture of a thermoplastic internal wall. Hereupon the external mandrel is removed and the thermoplastic internal wall is filled with a cooling liquid. Hereupon additional thermoplastic material is provided to the external side of the thermoplastic wall and is consolidated either during the provision hereof, or thereafter or both. Hereupon the cooling liquid is removed and the container is ready for being used.

Disclosed is a partly reusable and removable hollow mandrel (1) for filament winding of a fibrous vessel (14), the mandrel comprising: - removable and reusable parts comprising a plurality of elongated segments (6) having first (2) and second (32) ends, and first engaging means engaged with the first ends for holding the elongated segments in position; - a first end fitting (8) provided to be left behind in the fibrous vessel after the filament winding, the first end fitting having an opening (4) large enough to allow passage of the removable and reusable parts. Also dislosed is a method for assembling such a mandrel, a method for producing a leak- tight vessel using this mandrel, and a leak- tight vessel (14) produced that way.

Disclosed is a method for producing a leak- tight vessel (14) for holding a gas and/or liquid, comprising the steps of winding a heat - sealable thermoplastic barrier strip (60) around a removable mandrel (1) in such a way that each strip fragment overlaps with a substantially parallel strip fragment over at least a lateral overlapping distance, consolidating the overlapping strip fragments so as to form a gas and/or liquid tight layer (49), winding a fibrous material (12) around the gas and/or liquid tight layer (49), thereby leaving an opening (4) large enough for removing the mandrel (1). Further disclosed is a leak- tight vessel (14) produced in this way.

The invention relates to a method for producing a leak-tight vessel comprising the steps of: - assembling an at least partly removable mandrel; - mounting an end fitting to the mandrel, the end fitting having an opening large enough to allow passage of the at least partly removable mandrel after disassembly; forming a shell layer by filament winding over the mandrel and over the end fitting; applying a gas and/or liquid tight layer to an inner surface of the shell layer; disassembling and removing at least part of the mandrel, while leaving the first end fitting in the shell layer. The invention also relates to such a leak-tight vessel.
