An inflator for a vehicle occupant restraint system comprising: a hollow rupturable plastic inner shell; a propellant in said inner shell capable of developing fluid pressure internally thereof sufficient to rupture said inner shell; an outer shell comprising a plurality of resin impregnated carbon fibers wound about a major portion of said inner shell; and means for controlling the location of rupture of said inner shell comprising an orifice plate juxtaposed against an exterior surface of said inner shell and having a gas discharge orifice therein, the orifice in said orifice plate exposing the exterior of said inner shell to ambient pressure whereby controlled rupture of said inner shell occurs at said orifice upon the occurrence of a predetermined pressure differential across the portion of said inner shell underlying the orifice in said orifice plate.
