Method of Making a Composite TankA composite tank for containing liquid oxygen and the method of making the same wherein a water-soluble mandrel having the desired tank configuration and a cylindrical A method of making a composite tank for containing liquid oxygen configuration of the mandrel and an outer boss conforming to the configuration of the inner boss, the bosses each having a tubular portion for receiving the protuberance on the mandrel and a spherical portion. The mandrel and the bosses are first coated with a nickel coating. The mandrel is then wrapped with graphite fibers wetted with an epoxy resin and this resin is cured. A layer of insulating foam is then applied to the tank and cured. The insulating foam is machined to a desired configuration and a layer of aramid fibers wetted with a second epoxy resin is wrapped around the tank. The second resin is cured and the water soluble mandrel is washed from inside the tank.
