Receptacle for the storage of fluid under pressure, to breaking without fragmentation.

摘要

-The subject of the invention is a vessel of the type including an internal casing the shape of a body of revolution about a longitudinal axis (5) exhibiting a cylindrical central part or hoop (2) and two end parts (3), at least one of the said end parts being domed outwards, a binding of strong fibres coated with a thermoplastic or heat-curable binder surrounding the said casing and exhibiting, facing the hoop (2), at least one layer of fibres deposited circumferentially, termed circumferential fibres (C), and at least one layer of fibres, termed longitudinal fibres (L), deposited in a planar manner with a winding angle which is as small as possible so as to leave free, at the domed end part (3), a cap (4) centred on the said longitudinal axis, characterised in that the said hoop (2) furthermore includes at least one layer of fibres (Ln) deposited in a planar or helical manner with a winding angle ( alpha n) lying between that ( alpha ) of the said longitudinal fibres, and 90 DEG . -Application particularly to bottles (cylinders) for storing gas.
