MANDREL FOR MANUFACTURE OF THE HIGH PRESSURE VESSELS MADE OUT OF THE COMPOSITE MATERIALS

FIELD: mechanical engineering industry; other industries; devices for production of the high pressure vessels by the method of coiling of the reinforcing materials. ^ SUBSTANCE: the invention is pertaining to production of the high pressure vessels by the method of coiling of the reinforcing material and may be used in mechanical engineering industry. The mandrel for manufacture of the high pressure vessels out of the composite materials contains the thin-wall sealing body with the holes. Inside the sealing body feed the binary mixture releasing in the process of the chemical reaction the gas creating the necessary internal pressure and ensuring the necessary rigidity of the sealing body in the process of the coiling and the composite material solidification. Usage of the invention will provide the reliable rigidity at the presence of the minimal polar holes in the sealing body and simplification of the process of manufacture of the high pressure vessels. ^ EFFECT: the invention ensures the reliable rigidity of the high pressure vessels at the presence of the minimal polar holes in the sealing body and simplification of the process of manufacture of the high pressure vessels. ^ 1 dwg
