Problems solved by technology

The grille structure is molded on the outside of the gas cylinder and then assembled, which may lead to poor overall performance of the gas cylinder
On the other hand, only the grille structure is strengthened on the body of the gas cylinder, but the two ends of the cylinder head are not protected.

Embodiment Construction

[0043] A technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0044] like Figure 1-Figure 2 As shown, the shape of the grid structure on the surface of the gas cylinder is shown in the figure, including the gas cylinder liner 3, the metal gas cylinder opening end 2 and the metal gas cylinder tail end 6, and the two ends of the gas cylinder liner 3 are respectively connected to the metal gas cylinder. The open end 2 of the metal gas cylinder and the tail end 6 of the metal gas cylinder also include fiber-reinforced resin-based composite material 4 that is prestressed and wound on the outer surface of the inner liner 3 of the gas cylinder, the open end 2 of the metal gas cylinder, and the outer surface of the tail end 6 of the metal gas cylinder. The outer surface of the reinforced resin-based composite material 4 continues to be wound with a grid structure reinforcement layer 1, a fiber protectio...

Abstract

The invention discloses a non-Newtonian fluid impregnated grid enhanced hydrogen storage pressure vessel structure and process. The pressure vessel structure comprises a fiber reinforced resin matrixcomposite material, a grid structure reinforcing layer, a fiber protective layer and anti-collision materials arranged at end sockets at the two ends which are sequentially arranged on the outer sidesurfaces of a gas cylinder lining, an open end and a tail end of a metal gas cylinder outwards in a prestress winding mode, wherein the whole gas cylinder container structure is reinforced through thegrid structure reinforcing layer, fibers used for forming the grid structure reinforcing layer are impregnated with non-Newtonian fluid, gum dipping winding forming is carried out after drying treatment, soft grid structure molds at a cylinder body and two ends of the end sockets are molded and manufactured by utilizing a casting molding method, then adhering the soft grid structure molds to theouter surface of a gas cylinder wound with a fiber reinforced resin matrix composite material in a common adhering manner, and then molding a grid structure reinforcing layer. The prepared hydrogen storage pressure vessel has the characteristics of high rigidity, impact resistance, light weight and low cost.

Description

technical field [0001] The invention belongs to a pressure vessel structure and a molding process in the field of composite material hydrogen storage pressure vessels, and in particular relates to a grid-enhanced hydrogen storage pressure vessel structure and a molding process. Background technique [0002] Today's world energy structure is undergoing a transition from fossil energy to renewable new energy, in which hydrogen energy is regarded as the final form of energy utilization in the automotive industry due to its high energy conversion efficiency and clean and non-polluting characteristics. Therefore, the on-board hydrogen storage pressure vessel for hydrogen has extensive research significance and application value. [0003] At present, the commonly used hydrogen storage pressure vessels can be mainly divided into the following four types according to the structure and composition. Type I bottles are completely composed of metal. Although type II bottles are also mad...
