US Patent 11852297 Containers and methods for protecting pressure vessels

A container includes one or more hollow shell assemblies, each assembly having a first hollow shell including a first inner surface to cover a portion of a pressure vessel (PV) and a second hollow shell including a second inner surface attachable to the first hollow shell. The first and/or second hollow shells may include a fiber layer that may be at least partially impregnated with resin, and an energy dissipating material that is substantially concentric with the inner surfaces of the respective shells. The first and second hollow shells are attachable to one another to define a volume for at least partially enclosing the PV, and may be overwrapped via filament winding.
