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] Such as 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 protec...

Abstract

The invention discloses a non-Newtonian fluid impregnated grid reinforced hydrogen storage pressure vessel structure and technology. It includes fiber-reinforced resin-based composite materials that are prestressed and wound on the inner liner of the gas cylinder, the open end of the metal gas cylinder and the outer surface of the tail end, the reinforcement layer of the grid structure, the fiber protection layer and the anti-corrosion protection at the two ends of the head. The entire structure of the gas cylinder container is reinforced with a grid structure reinforcement layer, and the fibers used in the formation of the grid structure reinforcement layer are impregnated with non-Newtonian fluid, dried and then impregnated and wound; firstly, the casting method is used The soft grid structure molds for the cylinder body and the two ends of the head are molded separately, and then bonded to the outer surface of the gas cylinder after winding the fiber reinforced resin-based composite material by joint bonding, and then the grid structure reinforcement layer is formed. The hydrogen storage pressure vessel prepared by the invention 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...
