A pressure vessel includes a composite wall and a boss. The composite wall includes an outer shell, an inner liner disposed within the outer shell, and a port in the wall through which fluid may be communicated between an exterior of the pressure vessel and an interior of the pressure vessel. The boss is disposed at the port. The boss includes a neck projecting interiorly into the pressure vessel and a flange extending radially outward from the neck. The liner contacts the flange and does not contact at least an interiorly extending portion of the neck.

Boss with inverted neck

An assembly is configured for use in a system for forming filament windings on a vessel having a circumference and a length. The assembly includes an endless belt and first and second rollers. The endless belt is configured to wrap partially around the circumference of the vessel to contact and impart pressure on a filament winding disposed on an outside surface of the vessel. The endless belt moves around the first and second rollers. A space is disposed between the first and second rollers to allow a filament wind eye of the system to move in a reciprocal motion along the length of the vessel. A method of using a machine for forming filament windings on a vessel having a circumference and a length is also described.

Device for stabilizing localized dome reinforcement

A vehicle is provided. The vehicle can include a cab, a plurality of wheels, one or more frame rails, an engine or power generation system, and a pressure vessel. The frame rails are configured to support the cab and the plurality of wheels. The engine or power generation system are configured to be powered by a fuel. The pressure vessel is configured to store the fuel to be used by the engine or power generation system. The pressure vessel can include a structural shell formed by filament winding upon a substantially cylindrical form.

Vehicles having composite interwoven gas containment assemblies

A pressure vessel is provided that has a structural shell formed by winding filaments upon a substantially cylindrical form. The structural shell has a first filament and a second filament. The first filament includes of a first material. The first filament is wound about the form in a primarily hoop direction. The second filament includes a second material. The second material is different from the first material. The second filament is wound about the form in a primarily helical direction. The first filament and second filament are interwoven in a layer upon the form.
