    Abstract: A process for winding a filament around a winding support having a general cylindrical shape with dome-shaped longitudinal ends and having a roll axis, by which the winding support is held by a holding device fixed to a base. The following steps occur in synchronization: (i) feeding a filament, by at least one primary feeding device and at least one secondary feeding device, towards the winding support; (ii) translating the primary feeding device and the secondary feeding device with respect to the base in parallel to the roll axis of the winding support; and (iii) rotating the winding support around its roll axis with respect to the base, where the movement of the primary feeding device and the secondary feeding device are symmetric one of another.

    Abstract: A pressure vessel including an internal fluid storage chamber, and an outer composite structure enclosing or encasing the internal fluid storage chamber. The outer composite structure has a thickness containing both helical layers and hoop layers of reinforcing fibers, wherein at least 20% of a combined thickness of all of the helical layers are located within a 25% innermost thickness of the outer composite structure. The internal fluid storage chamber is defined by a liner including a generally cylindrical central portion having a first outer diameter at a first longitudinal end, and a first dome-shaped longitudinal end portion having a base portion and a first intermediate portion located between the generally cylindrical central portion and the base portion for connecting the first longitudinal end of the generally cylindrical central portion to the base portion of the first dome-shaped longitudinal end portion.
