Abstract
A method of manufacture of large high pressure composite bottles. In accordance with the method, polar caps are placed on the ends of a reusable mandrel, which is then coated with an appropriate mold release and then coated or at least covered with a material which will become the internal protective coating for the finished bottle, and then coated with an impervious liner material. Thereafter, a few layers of windings of high strength resin impregnated filament are put on the mandrel and the resin is cured to make the internal protective coating and liner self-supporting. The resulting thin shell is then cut circumferentially near the middle thereof and the two halves are removed from the mandrel, then rebonded together so that the thin shell may act as a self-supporting mandrel over which the structural shell of the bottle is subsequently wound. This allows the original mandrel to be used over and over again as desired. Various details and variations of the method are disclosed.
