摘要： The invention relates to a method for the manufacture of a leak-tight vessel comprising a cylindrical mantle and two dome-shaped ends for the storage of a gas and/or a liquid. The method comprises providing an inner barrier layer comprising a heat-sealable thermoplastic material and an outer shell layer comprising a fiber-reinforced heat-sealable thermoplastic material, as well as an end-fitting. Further, the method comprises providing an inner layer by winding a heat-sealable thermoplastic filament material and forming an outer layer in two steps: first providing around the mantle of the vessel a fabric of a fiber-reinforced heat-sealable material, whereby the width of the fabric diminishes with successive windings of the fabric around the mantle, followed by winding a fiber-reinforced heat-sealable plastic film over the fabric around the mantle and the dome-shaped endings.

摘要： The present invention describes a method for producing a leak-tight vessel for holding a gas and/or liquid, comprising the steps of winding a heat-sealable thermoplastic barrier strip around a removable mandrel 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, winding a fibrous material around the gas and/or liquid tight layer, thereby leaving an opening large enough for removing the mandrel. The invention also describes a leak-tight vessel produced in this way.

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.

摘要： The invention relates to a method (100) for producing a fibre composite tank (60) for containing at least a fluid (30) and an equipment (10), the method comprising:
a) a step (110) of assembling complementary portions (21, 22) of a liner (20) around the equipment (10) and/or maintaining support holding said equipment;
b) a step (120) of sealing the complementary portions (21, 22) together, so as to form the liner (20) with the equipment stable inside said liner;
c) a step (130) of introducing the fluid (30) into the liner (20) through openings (24) formed in said liner; and
d) a step (150) of forming a shell layer (50) by winding a composite tape around the liner (20), said composite tape being made of a thermoset or thermoplastic composite material.
The invention relates also to a fibre composite tank (60) for containing at least a fluid (30) and an equipment (10), produced by the method (100) and forming a unitary rigid structure able to withstand an overpressure of at least 2 bars.
