Abstract
A polar end ring mechanism for use with composite pressure vessels. The end ring is designed to support a pressure vessel during its formation via filament winding. The end ring helps define an opening at one of the polar ends of a tank. Spikes positioned along a portion of the end ring help prevent rotation or translation of the tank during formation and provide an improved mechanical lock with the tank body. A cap may then be secured to the polar end ring after formation in order to close the pressure vessel.
Claims9
An end ring for use in filament winding a pressure vessel, comprising:
- an outer flange defining a first end of the end ring;
- and
- a platform comprising a side surface and an end surface, the platform inward of the outer flange along an axis, wherein the end surface of the platform defines a second end of the end ring such that the platform and the outer flange define opposing ends of the end ring along the axis,
- wherein the end ring defines a central opening extending from the first end to the second end,
- wherein at least one spike extends outwards in a radial direction relative to the central opening from the side surface of the platform,
- wherein the at least one spike comprising a base dimension and a tapered portion, the tapered portion having a smaller dimension than the base dimension, and
- wherein at least one pocket is defined in the end surface of the platform, the at least one pocket comprising a pocket surface recessed into the platform.
