The invention can be used for the pressurised storage of gases. The aim of the invention is to provide a pressurised container consisting of fibre-reinforced plastic with flat or practically flat lids. To achieve this, wound axially aligned reinforcement structures run through the interior of the body and absorb the major part of the required forces on their plane of alignment. The invention is characterised in that fibre strands are distributed uniformly over the cross-sectional surface of the cylindrical pressurised container, are aligned axially and fixed to flat or practically flat lids. In one advantageous embodiment of the invention, a container is formed by the spiral winding of an essentially unidirectional fibre-layer, which is thicker at its edges. Reinforcement layers, which are arranged in a circumferential direction and exert a radial action, cover the reinforcement strands or the spirally wound unidirectional fibre-layer, said layers forming the casing of the pressurised container.

La présente invention peut s'appliquer au stockage sous pression de gaz et a pour objectif de mettre au point un récipient sous pression en matière plastique renforcée par des fibres qui présente des couvercles plans ou quasiment plans. A cette fin, des structures de renfort enroulées à alignement axial traversent l'espace intérieur du corps et absorbent la majeure partie des forces nécessaires dans leur plan d'alignement. Cette invention est caractérisée en ce que des brins de fibres sont répartis de manière uniforme sur la surface de section transversale du récipient sous pression cylindrique, alignés en direction axiale de manière précise et fixés sur des couvercles plans ou quasiment plans. Cette invention est également caractérisée en ce qu'un récipient est formé par enroulement en spirale d'une couche de fibres majoritairement unidirectionnelle qui est plus épaisse aux extrémités. Des couches de renfort à orientation périphérique, qui agissent en direction radiale et forment la fermeture du récipient sous pression, sont appliquées sur les brins de renfort ou sur la couche de fibres unidirectionnelle enroulée en spirale.
