Abstract

A pressure vessel includes an outer filament wound shell with one closed and one open end and an inner filament wound shell of lower hoop strength having a closed end adjacent the open end of the outer shell and an open end adjacent the closed end of the outer shell. The inner shell is a loose fit within the outer shell and under pressure expands to functionally grip the outer shell to prevent slippage. The winding of the shell is such that upon expansion of the inner shell they combine to form a composite shell of the desired strength. Where the shells are used to form propellant contg. rocket nozzles the winding is such that the composite shell has a hoop strength twice its axial strength. The filaments are pref. glass and the resin of the shells is pref. an epoxy resin.
