Filament wound pressure vessel with on-line monitoring function and its manufacturing process

Abstract

The invention relates to a fiber winding pressure container with an on-line monitoring function and a manufacturing process thereof. The fiber winding pressure container comprises a liner, and the liner surface is provided with a fiber composite winding layer provided with a conductive sensing network for collecting electrical signals. The manufacturing process comprises the steps that a conductive nano material is added to a volatile solvent and stirred to prepare a conductive nanometer solution; a metal template is placed on the surface of the fiber composite winding layer to be wound on the outer layer of the liner; the conductive nanometer solution is sprayed on the fiber composite winding layer through the metal template; and the fiber composite winding layer is heated, so that the volatile solvent is completely evaporated, and the conductive sensing network is formed on the surface of the fiber composite winding layer. Compared with the prior art, the fiber winding pressure container has the advantages of being simple, reliable, capable of achieving on-line monitoring and the like.

Description

technical field [0001] The invention relates to a pressure vessel, in particular to a filament-wound pressure vessel with on-line monitoring function and its manufacturing process. Background technique [0002] Filament-wound pressure vessels with metal or plastic linings have the advantages of light weight, high strength, and superior performance ratio, and have been widely used in cutting-edge military fields such as aerospace and aviation, and civilian fields such as energy and chemical engineering. The design, manufacture, installation and operation of filament wound pressure vessels may cause abnormal failure and cause sudden damage accidents. During the failure process of the filament wound pressure vessel, damages such as fiber breakage and interlayer delamination in the fiber layer often occur before the complete failure of the pressure vessel, so the real-time perception and early warning of the fiber layer damage in the filament wound pressure vessel can be monitor...
