FIELD: automotive industry.
SUBSTANCE: high-pressure vessel comprises load-bearing shell made of a composition material, sealing shell, coaxial metallic connecting pipes with flanges embedded in the sealing shell, and nuts screwed on the connecting pipes. The sealing shell is made of two interconnected composition hemispherical molded shells. The method comprises winding composition layer on the preliminary prepared sealing shell and polymerizing the layer. The sealing shell is made of two half shells provided with openings for connecting pipes. Each shell is molded from the composition material with the use of punch and mold. The connecting pipes are glued. The half shells are interconnected. The outer load bearing shell is wound, and it is additionally secured to the connecting pipe through a nut.
EFFECT: enhanced permissible loading and decreased weight and cost.
